Description
GM6250 combine high accuracy with very low power con-
sumption, and provides high output current even when the
application requires extremely low input-output voltage dif-
ferential.
GM6250 includes a precision voltage reference, an error
correction circuit, over-temperature protection, and a cur-
rent limited output driver. Fast transient response to load
variations provides excellent stability under dynamic load
conditions.
GM6250 comes in SOT-23 (150mW), SOT-89 (500mW)
and TO-92 packages.
Features
Maximum output current 250mA (within
maximum power dissipation)
Output voltage: from 1.8 V to 5.0V in 0.1V
increments
Output voltage ±2%
CMOS low power consumption, typically
1.0µA at V
OUT
= 5.0V
Input stability typically 0.2%/ V
Ultra-low dropout voltage 0.38V @ I
OUT
=
200mA at V
OUT
= 5.0V
Small input/ output differential:
0.4V at 160mA (V
OUT
= 3.3V)
