LDI1117-3.3H Low Dropout (LDO) Regulator in a SOT-223 Case Outline

Diotec's +3.3 V regulator offers a high output current of 1.35 A, thermal overload, and short-circuit protection

Image of Diotec's LDI1117-3,3H Low Dropout RegulatorDiotec's LDI1117-3.3H is a fixed LDO voltage regulator that provides +3.3 V with ±1% tolerance and an output current of up to 1.35 A. The regulator is assembled in a powerful SOT-223 case outline, offering a backside cooling area for easy heat removal at higher ambient temperatures.

The LDI1117-3.3H features thermal overload and short-circuit protection avoiding damage to the part itself and the circuit supplied from it. These regulators are suitable for applications including control boards for dish washers, washing machines, and microwave ovens, as well as industrial controls, power supplies, and motor drives.
