Product Description
The CM3018 is a very low dropout, low noise regulator
that delivers up to 150mA of load current at a fixed out-
put voltage.
A dedicated control input (EN, Active High) provides
power-up sequencing flexibility. When this input is
taken low, the regulator is disabled. In this state, the
supply current will drop to near zero. An internal dis-
charge MOSFET resistance (300Ω) will force the out-
put to ground whenever the device is disabled.
An optional bypass pin is provided for further improve-
ment of noise performance and to maximize the power
supply ripple rejection.
The CM3018 is fully protected, offering both overload
current limiting and high temperature thermal shut-
down.
The CM3018 is available in a tiny 5 lead SOT-23 pack-
age or a 5-bump CSP and is ideal for space critical
applications. The CSP version of the CM3018 incorpo-
rates OptiGuardTM technology to provide increased reli-
ability at assembly.
All versions of the CM3018 are now available with
optional lead-free finishing.
