Description
ACE504A
Wide Input Voltage Range, 150mA ULDO Regulator
ACE504A series are positive voltage regulator IC fabricated by high voltage EPNP process.
The ACE504A has features of wide input voltage range and high accuracy, high ripple rejection, low
dropout voltage, low noise, current limit and ultra-low quiescent current which make them ideal for use in
various USB and portable device.
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.
ACE504A has adjustable, 1.8V,3.3V,5.0V fixed voltage versions.
The ACE504A is available in space saving SOT-23-5 an SOT-89-3 packages.

Note 1: Stressed greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under “ Recommended Operating Conditions” is not implied. Exposure to “Absolute Maximum Ratings” for extended periods may
affect device reliability.
