300mA RF ULDO REGULATOR AP2210

Data Sheet

Jan. 2012 Rev. 1. 6 BCD Semiconductor Manufacturing Limited

General Description

The AP2210 is a 300mA ULDO regulator which pro-

vides very low noise, ultra low dropout voltage

(typically 250mV at 300mA), very low standby current

µA maximum) and excellent power supply ripple

rejection (PSRR 75dB at 100Hz) in battery powered

applications, such as handsets, PDAs and in noise sen-

sitive applications, such as RF electronics.

The AP2210 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 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.

Typical Application of AP2210 (Note 7) Note 7: Dropout voltage is 250mV when TA=25oC. In order to obtain a normal output voltage, VOUT+0.25V is the minimum input voltage which will results a low PSRR, imposing a bad influence on system. Therefore, the recommended input voltage is VOUT+1V to 13.

Data Sheet 300mA RF ULDO REGULATOR AP2210 Application Information Input Capacitor A 1µF minimum capacitor is recommended to be placed between VIN and GND. ture must be within the range specified under absolute maximum ratings to avoid thermal shutdown. To determine if the power dissipated in the regulator reaches the maximum power dissipation (see figure 16, 17), using: TJ = PD*θJA + TA PD=(VIN-VOUT)*IOUT+VIN*IGND Output Capacitor It is required to prevent oscillation. 1.
