AP2205
WIDE INPUT VOLTAGE RANGE, 200mA ULDO REGULATOR
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.
