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 1
.
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.
