● Input voltage range: 2.7V to 18V ● Available in fixed voltage option: 5V ● Output voltage tolerances of ±2% ● Rated output current: 300mA ● Ultra Low Quiescent current: typical 1.5µA ● Typical 400mV dropout voltage (IOUT=100mA, 5V output) ● Internal short-circuit current limit ● Internal thermal overload protection ● SOT23-3L package

AWP37200B500 is a ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. With less than 1.5μA quiescent current at no load, the AWP37200B500 is ideally suited for standby micro-control-unit systems, especially for always-on applications like E-meters, fire alarms, smoke detectors and other battery operated systems. With adequate heat sinking, the AWP37200B500 can deliver 300mA output current. Current limiting is included to limit the peak output current to a safe value. The AWP37200B500 retains all of the features that are common to low dropout regulators including a low dropout PMOS pass device, short circuit protection, and thermal shutdown.. The AWP37200B500 is available in SOT23-3L package, which is useful for cost-effective board manufacturing.
