AP2210 - 300mA RF ULDO REGULATOR

General Description

The AP2210 is a 300mA ULDO regulator which provides 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).

Key Features

  • individual logic compatible enable/shutdown control inputs, a low power shutdown mode for extended battery life, overcurrent protection, overtemperature protection, and reversed current 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 the space saving SOT-23-3 and SOT-23-5 packages. Pin Assignments (Top View) VIN 3 1 2 GND VOUT SOT-23-3 (Top View) VIN 1 GND 2 EN 3 5 VOUT 4 BYP/ADJ SOT-23-5 Features.
  • Up to 300mA.

AP2210 300mA RF ULDO REGULATOR Description The AP2210 is a 300mA ULDO regulator which provides 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). This device is used in battery powered applications, such as handsets and 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 extended battery life, overcurrent protection, overtemperature protection, and reversed current 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 the space saving SOT-23-3 and SOT-23-5 packages.
