STMicroelectronics LDL40 200mA Low-Dropout (LDO) Voltage Regulator
STMicroelectronics LDL40 200mA Low-Dropout (LDO) Voltage Regulator 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 40V 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 STMicroelectronics LDL40 in shutdown mode, allowing a total current consumption lower than 0.3µA. Thermal protection is also included. The device is available in automotive grade in a very small footprint DFN package with wettable flanks, allowing the maximum space saving in the PCB (printed circuit board) design and AOI (automated optical inspection).
