Features

Description

GM6155 is an efficient linear voltage regulator with ultralow

- noise output, very low dropout voltage (typically 17mV at

light loads and 165mV at 50mA), and very low ground cur-

rent (600µA at 100mA output). GM6155 provides better

than 1% initial accuracy.

Ultra low noise output

High output voltage accuracy

Extremely accurate output voltage

Guaranteed 150mA output

Low quiescent current

Designed especially for hand-held, battery-powered de-

vices, GM6155 includes a CMOS or TTL compatible en-

able/ shutdown control input. When shutdown, power con-

sumption drops nearly to zero. Regulator ground current in-

creases only slightly in dropout, further prolonging battery

life. Key features of GM6155 include a reference bypass

pin to improve its excellent low-noise performance, re-

versed-battery protection, current limiting, and over-

temperature shutdown.

Low dropout voltage

Extremely tight load and line regulation

Very low temperature coefficient

Current and thermal limiting

Reverse-battery protection

"Zero" off-mode current

Logic-controlled electronic enable

The GM6155 is available in SOT-25 package.

Application

Cellular telephones

Consumer/ personal electronics

Laptop, notebook, and palmtop computers

Battery-powered equipment

SMPS post-regulator/ dc-to-dc modules

High-efficiency linear power supplies

PCMCIA V and V regulation/ switching

CC PP
