BCD Semiconductor Manufacturing Limited AP2201
The AP2201 is a 150mA output current fixed voltage regulator designed to provide 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. The AP2201 also features individual logic compatible enable/shutdown control inputs, a low power shutdown mode for extended battery life, over current protection, over temperature protection, as well as reversed-battery protection. The Applications output capacitor should have 5Ω or less ESR, tantalum or aluminium electrolytic capacitors are adequate.
