AP2210 300mA RF ULDO REGULATOR Description Pin Assignments The AP2210 is a 300mA ULDO regulator which provides very low noise, ultra low dropout voltage (typically 250mV at 300mA), very low (Top View) standby current (1A maximum) and excellent power supply ripple VIN rejection (PSRR 75dB at 100Hz) in battery powered applications, 3 such as handsets, PDAs and in noise sensitive applications, such as RF electronics. The AP2210 also features individual logic compatible enable/shutdown control inputs, a low power shutdown mode for 1 2 extended battery life, over current protection, over temperature GND VOUT protection, as well as reversed-battery protection. SOT-23-3 The AP2210 has 2.5V, 2.8V, 3.0V, 3.3V, 3.6V, 4.0V, 5.0V and ADJ versions. (Top View) The AP2210 is available in space saving SOT-23-3 and SOT-23-5 5 VOUT VIN 1 packages.

In order to obtain a normal output voltage, V +0.25V is the minimum input voltage which will result a low A OUT PSRR, imposing a bad influence on system. Therefore, the recommended input voltage is V +1V to 13.2V. For AP2210-3.0 version, its input voltage can OUT be set from 4V (V +1V) to 13.2V.
