ULTRA-LOW DROPOUT CMOS VOLTAGE REGULATORS
Revision 1, May 2002 www.gammamicro.com
PRELIMINARY
Maximum output current 150mA (V
OUT
= 3.0V)
Output voltage 1.8V to 6.0V in 0.1V increments
Output voltage
2%
CMOS Low power consumption
Input stability typ. 0.2%/V
Ultra-low dropout voltage (typ. 0.20V at 80mA, 0.38V at 160mA)
Stand-by current 0.1
A (V
OUT
= 3.0V)
SOT-25 (150mW) and SOT-89 (500mW) packages
The GM6150's combine high accuracy with very low power consumption, providing high output current even when
the application requires very low dropout voltage. The Chip Enable (CE) input allows the output to be turned off to
prolong battery life. The GM6150's include a precision voltage reference, error correction circuitry, and a current-
limited output driver. Fast transient response to load variations provides excellent stability under dynamic load
conditions. The CE function in the GM6150's is positive logic; also available are the GM6152's with negative logic.
The GM6150 is available in fixed output voltages from 1.8V to 6.0V in 0.1V increments, and in SOT-25 (150mW)
and SOT-89 (500mW) packages.
