1 / 22 page 300mA RF ULDO REGULATOR AP2210 Data Sheet 1 Mar. 2007 Rev. 1. 2 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 (1µA 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 and 3.3V versions. The AP2210 is available in space saving SOT-23-3 and SOT-23-5 packages.
