150ma Rf Uldo Regulator

The AP2201 is a 150mA output current fixed voltage Regulator designed to provide very low noise (45Vrms at 80Hz-100KHz), ultra low dropout voltage (typically 165mV at 150mA), very low quiescent current (1A maximum) and excellent power supply ripple rejection (PSRR 75dB at 100Hz) in battery powered applica- tions, 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-bat- tery protection. The output capacitor of 1.0F minimum and 2.2F minimum near its pin are recommended when CBYP is not used and when CBYP is 470pF respectively. The output capacitor should have 5 or less ESR, tantalum or aluminium electrolytic capacitors are adequate. Bypass capacitor is connected to the internal voltage reference to quiet noise. Its recommended value is from 470pF to 1nF. If output noise is not a major con- cern and rapid turn-on is necessary, omit CBYP and leave BYP open. The AP2201 has 2.6V, 2.8V and 3.0V versions now. The AP2201 is available in space saving 5-pin SOT- 23-5 package. By BCD Semiconductor Manufacturing Limited
