Data Sheet
WIDE INPUT VOLTAGE RANGE, 150mA ULDO REGULATOR
General Description
The AP2204 series is a positive voltage regulator IC
fabricated by high voltage EPNP process.
The AP2204 has features of wide input voltage range,
high accurcay, 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.
The AP2204 has 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V,
5.0V fixed voltage versions and adjustable voltage
version.
The AP2204 is available in space-saving SOT-23-5,
SOT-89 and PSOP-8 packages.
