Description
GM6156 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 (600A at 100mA output). GM6156 provides better
than 1% initial accuracy.
Designed especially for hand-held, battery-powered de-
vices, GM6156 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 GM6156 include a reference bypass
pin to improve its excellent low-noise performance, re-
versed-battery protection, current limiting, and over-
temperature shutdown.
The GM6156 is available in SOT-25 package.
