ADP166AUJZ-1.8-R7

ADP166AUJZ-1.8-R7 is a very low quiescent current, low dropout (LDO), linear regulator that operates from 2.2V to 5.5V and provides up to 150mA of output current. The low 120mV dropout voltage at a 150mA load improves efficiency and allows operation over a wide input voltage range. The ADP166 are specifically designed for stable operation with tiny 1µF ±30% ceramic input and output capacitors to meet the requirements of high-performance, space-constrained applications. Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. Applications include portable and battery-powered equipment, post dc-to-dc regulation, portable medical devices, wireless sensor network (WSN) devices.
