PRELIMINARY

CM3018

Micropower, 150mA Low Noise CMOS Regulator

with Fast Response

Features

Product Description

•

Available with 1.5V, 1.8V, 2.5V, 2.6V, 2.8V, 2.85V,

2.9V, 3.0V, 3.1V or 3.3V outputs

Fast (60µs) V response when enabled

The CM3018 is a very low dropout, low noise regulator

that delivers up to 150mA of load current at a fixed out-

put voltage.

•

OUT

Ultra low noise (35µV rms typ.)

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.

Delivers up to 150mA output current

Very low dropout (150mV at 150mA)

Low quiescent operating current (110µA)

Stable with low-ESR ceramic capacitors

“Zero” disable mode current consumption

Thermal overload protection

Foldback overload current protection

-40°C to +85°C temperature operation

Available in a 5-pin SOT23 and 5-bump Chip Scale

Packages (CSP)

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.

•

Lead-free versions available

Applications

•

Wireless handsets, PDAs, MP3 players, digital

cameras

PCs and notebooks

Graphics cards, set-top boxes

Compact Flash memory cards

Battery-powered devices

PC cards

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 OptiGuard^TMtechnology to provide increased reli-

ability at assembly.

•

All versions of the CM3018 are now available with

optional lead-free finishing.
