General Description
The MIC5233 is a 100 mA, highly accurate, low dropout
regulator with high input voltage and ultra-low ground
current. This combination of high voltage and low
ground current makes the MIC5233 ideal for multicell
Li-Ion battery systems.
A µCap LDO design, the MIC5233 is stable with either
ceramic or tantalum output capacitors. It only requires
a 2.2 µF output capacitor for stability.
Features of the MIC5233 include enable input, thermal
shutdown, current limit and reverse battery protection,
and reverse leakage protection.
Available in fixed and adjustable output voltage ver-
sions, the MIC5233 is offered in the 5-lead SOT23 and
3-lead SOT223 packages with a junction temperature
range of –40°C to +125°C.

Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the
maximum allowable power dissipation will cause the device operating junction temperature to exceed the
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.

4.0 APPLICATION INFORMATION
4.1 Enable/Shutdown
The MIC5233 comes with an active-high enable pin
that allows the regulator to be disabled. Forcing the
enable pin low disables the regulator and sends it into
a “Zero” Off mode current state, consuming a typical
0.1 µA. Forcing the enable pin high enables the output
voltage.
4.2 Input Capacitor
The MIC5233 has a high input voltage capability, up to
36V. The input capacitor must be rated to sustain volt-
ages that may be used on the input. An input capacitor
may be required when the device is not near the source
power supply or when supplied by a battery. Small
surface mount, ceramic capacitors can be used for
bypassing. A larger value may be required if the source
supply has high ripple.
4.3 Output Capacitor
The MIC5233 requires an output capacitor for stability.
The design requires 2.2 µF or greater on the output to
maintain stability. The design is optimized for use with
low-ESR ceramic chip capacitors. High-ESR capacitors
may cause high-frequency oscillation. The maximum
recommended ESR is 3Ω. The output capacitor can be
increased without limit. Larger valued capacitors help to
improve transient response.
X7R/X5R dielectric-type ceramic capacitors are recom-
mended because of their temperature performance.
X7R-type capacitors change capacitance by 15% over
their operating temperature range and are the most
stable type of ceramic capacitors. Z5U and Y5V dielectric
capacitors change value by as much as 50% and 60%,
respectively, over their operating temperature ranges. To
use a ceramic chip capacitor with Y5V dielectric, the
value must be much higher than an X7R ceramic capac-
itor to ensure the same minimum capacitance over the
equivalent operating temperature range.
4.4 No-Load Stability
The MIC5233 will remain stable and in regulation with
no load unlike many other voltage regulators. This is
especially important in CMOS RAM keep-alive
applications.
4.5 Thermal Consideration
The MIC5233 is designed to provide 100 mA of contin-
uous current in a very small package. Maximum power
dissipation can be calculated based on the output
current and the voltage drop across the part.
To determine the maximum power dissipation of the
package, use the junction-to-ambient thermal
resistance of the device and Equation 4-1:
EQUATION 4-1:
Table 4-1 shows examples of the junction-to-ambient
thermal resistance for the MIC5233:
TABLE 4-1: 5-LEAD SOT23 AND SOT-223
THERMAL RESISTANCE
The actual power dissipation of the regulator circuit can
be determined using Equation 4-2:
EQUATION 4-2:
Substituting PD(MAX) for PD and solving for the operating
conditions that are critical to the application will give the
maximum operating conditions for the regulator circuit.
For example, when operating the MIC5233-3.0YM5 at
+50°C, with a minimum footprint layout, the maximum
input voltage for a set output current can be determined
as follows:
EQUATION 4-3:
The junction-to-ambient (θJA) thermal resistance for
the minimum footprint is +235°C/W from Tab le 4-1. It is
important that the maximum power dissipation not be
exceeded to ensure proper operation. Because the
MIC5233 was designed to operate with high input
voltages, careful consideration must be given so as not
to overheat the device. With very high input-to-output
voltage differentials, the output current is limited by the
total power dissipation.

MIC5233
Total power dissipation is calculated using the following
equation:
EQUATION 4-4:
Due to the potential for input voltages up to 36V, ground
current must be taken into consideration.
If we know the maximum load current, we can solve for
the maximum input voltage using the maximum power
dissipation calculated for a +50°C ambient, 319 mW.
EQUATION 4-5:
Ground pin current is estimated using the typical
characteristics of the device.
EQUATION 4-6:
For higher current outputs, only a lower input voltage
will work for higher ambient temperatures.
Assuming a lower output current of 10 mA, the
maximum input voltage can be recalculated:
EQUATION 4-7:
Maximum input voltage for a 10 mA load current at
50°C ambient temperature is 34.55V, utilizing virtually
the entire operating voltage range of the device.
4.6 Adjustable Regulator Application
The MIC5233M5 can be adjusted from 1.24V to 20V by
using two external resistors (Figure 4-1). The resistors
set the output voltage based on the following equation:
EQUATION 4-8:
Feedback resistor R2 should be no larger than 300 kΩ.

Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
