The AP7201 is a dual low-dropout (LDO) CMOS linear regulator.

The device operates from 1.9V to 5.5V input and delivers up to

150mA per output channel.

The AP7201 includes a pass element, voltage reference, error

amplifier, current limit and built-in phase compensation. Key

features include individual logic-compatible enable/shutdown

control inputs, fold-back current limit and thermal shutdown

protections.

The AP7201 is fully compatible with low ESR ceramic capacitors,

reducing cost and improving output stability. The fixed output

voltage for each channel is set independently. Voltages are

100mV per step within a range of 1.0V to 3.3V.

The EN function allows the output of each channel to be turned

off

independently,

resulting

in

greatly

reduced

power

consumption. The AP7201 is available in the DFN2018-6

(USP-6B) package.
