AP2205中文资料WIDE INPUT VOLTAGE RANGE, 200mA ULDO REGULATOR数据手册Diodes规格书

描述 Description

The AP2205 series is a positive voltage regulator IC fabricated by high-voltage EPNP process.

The AP2205 has features of wide input voltage range, high accuracy, high ripple rejection, low dropout voltage, low noise, current limit and ultra-low quiescent current which make it ideal for use in various USB and portable devices.

The IC consists of a voltage reference, an error amplifier, a resistor network for setting output voltage, a current limit circuit for current protection, and a chip enable circuit, a low power shutdown mode for extended battery life, over current protection, over temperature protection, as well as reversed-battery protection.

The AP2205 has 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 5.0V fixed voltage versions and adjustable voltage version.

The AP2205 is available in space-saving SOT25 and SOT89 packages.
