Description

The ACE5023T is a high accuracy, low noise, high speed, low dropout CMOS Linear regulator with

high ripple rejection and fast discharge function. The device offers a new level of cost effective

performance in cellular phones, surveillance system, Bluetooth, wireless and other portable electronic

devices.

ACE5023T can provide product selections of output value in the range of 1.0V~3.6V by every 0.1V step.

The current limiter's fold-back circuit also operates as a short circuit protection and an output current

limiter at the output pin.

The ACE5023T regulators are available in standard SOT23-5 and DFN1x1-4 packages. Standard

products are Pb-free and Halogen-free.
