AP2202集成电路（IC）的线性+开关稳压器规格书PDF中文资料

General Description

The AP2202 is a 150mA ULDO regulator which provides very low noise (45µVrms at 80Hz-100KHz), ultra low dropout voltage (typically 165mV at 150mA), very low quiescent current (1µA maximum) and excellent power supply ripple rejection (PSRR 75dB at 100Hz) in battery powered applications, such as handsets and PDAs and in noise sensitive applications, such as RF electronics.
