AP2210 Datasheet | BCD Semiconductor

300m A RF ULDO REGULATOR General Description Features Data Sheet AP2210 The AP2210 is a 300m A ULDO regulator which provides very low noise, ultra low dropout voltage (typically 250m V at 300m A), very low standby current (1µA maximum) and excellent power supply ripple rejection (PSRR 75d B at 100Hz) in battery powered applications, such as handsets, PDAs and in noise sensitive applications, such as RF electronics. The AP2210 also Features individual logic patible 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 AP2210 has 2.5V, 2.8V, 3.0V, 3.3V, 3.6V, 4.0V, 5.0V and ADJ versions. The AP2210 is available in space saving SOT-23-3 and SOT-23-5 packages. - Up to 300m A Output Current - Excellent ESR Stability - Low Standby Current - Low Dropout Voltage: VDROP=250m V at 300m A - High Output Accuracy: ± 1% - Good Ripple Rejection Ability: 75d B 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 - Wireless municators - PDAs/Palmtops - PC Mother Board - Consumer Electronics Jan. 2012 Rev. 1. 6 SOT-23-3 SOT-23-5 Figure 1.
