Product Description

The CM3002 family of regulators are very low dropout

regulators that deliver up to 1.0A of load current at a

fixed voltage output. Input and output voltage options

for the CM3002 family devices are presented in

Table

Operating from a single input supply, these devices are

ideally suited for powering low voltage “core” proces-

sors, especially where a 3.3V source is already avail-

able.

These regulators feature a dedicated control input (EN,

Active High) for power-up sequencing flexibility. When

this input is taken low, the regulator output is disabled.

In this state, the supply current will drop to a low level

to ensure all the internal control circuitry still remains

active. This provides excellent start-up response when-

ever the device comes out of shutdown.

The CM3002 family of regulators is fully protected,

offering both overload current limiting and high temper-

ature thermal shutdown. Housed in space saving ther-

mally-enhanced SOIC-8 and MSOP-8 (CM3002-33MA/

MF) packages, these devices ensure maximum junc-

tion-to-ambient power dissipation.

The CM3002 is available with optional lead-free finish-

ing.
