1 / 33 page 150mA RF ULDO REGULATOR AP2202 Data Sheet 1 Mar. 2007 Rev. 1. 7 BCD Semiconductor Manufacturing Limited General Description The AP2202 is a 150mA ULDO regulator which pro- vides very low noise, ultra low dropout voltage (typically 165mV at 150mA), very low standby 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 AP2202 also features 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 pro- tection. The AP2202 has adjustable, 2.5V, 2.6V, 2.7V, 2.8V, 2.9V, 3.0V, 3.3V and 4.0V versions. The AP2202 is available in space saving SOT-23-5 and SOT-89-3 packages. Features · Up to 150mA Output Current · Low Standby Current · Low Dropout Voltage: VDROP=165mV at 150mA · High Output Accuracy: ±1% · Good Ripple Rejection Ability: 75dB at 100Hz and IOUT=100µA · Tight Load and Line Regulation · Low Temperature Coefficient · Over Current Protection · Thermal Protection · Reverse-battery Protection · Logic-controlled Enable Applications · Cellular Phones · Cordless Phones · Digital Still Cameras · Wireless Communicators · PDAs / Palmtops · PC Mother Board · Consumer Electronics SOT-23-5 Figure 1.
