LDL40 LDO Linear Regulators
STMicroelectronics' high-accuracy voltage regulators connect to batteries in automotive or industrial applications
STMicroelectronics' LDL40 is a high-accuracy voltage regulator designed to be directly connected to a car battery in automotive applications or a generic battery used in industrial applications. Extended input voltage up to 40 V makes the device able to support a load dump transient, which is typical in automotive systems. Ultra-low quiescent current at light load increases the battery operation lifetime in always-on standby systems. The device is stabilized with a small ceramic capacitor on the input and output.
An enable logic control function puts the LDL40 in shutdown mode, allowing a total current consumption lower than 0.3 μA. Thermal protection is also included. The device is available in automotive grade in a very small footprint DFN package with a wettable flank, allowing the maximum space saving in the PCB (printed circuit board) design and AOI (automated optical inspection).
