ULTRA - LOW DROPOUT POSITIVE VOLTAGE REGULATOR
Power Management
Features
Description
Maximum output current 250mA (within
The GM6250's combine high accuracy with very low power
maximum power dissipation)
consumption, providing high output current even when the
Output voltage: from 1.8 V to 6.0V in 0.1V
application requires extremely low input-output voltage dif-
increments
ferential.
Output voltage ±2%
The GM6250's include a precision voltage reference, an er-
CMOS low power consumption, typically
ror correction circuit, over-temperature protection, and a
1.0µA at VOUT = 5.0V
current limited output driver. Fast transient response to
Input stability typically 0.2%/ V
load variations provides excellent stability under dynamic
Ultra-low dropout voltage 0.38V @ IOUT =
load conditions.
200mA at VOUT = 5.0V
The GM6250's come in SOT-23 (150mW), SOT-89
(500mW) and TO-92 packages.
Small input/ output differential:
0.4V at 160mA (VOUT = 3.3V)

DIRECTIONS FOR USE
Notes on Use
1. Please use this IC within the stipulated absolute maximum ratings as the IC is liable to malfunction
outside of such parameters.
2. There is a possibility theat oscillation may occur as a result of the impedance present between the
power supply and the IC's input. Where impedance is 10W or more, please use a capacitor (CIN)
of at least 1µF.
With a large output current, operations can be stabilised by increasing capacitor size (CIN). If CIN is
small and capacitor size (CL) is increased, there is a possibility of oscillation due to input impedance.
In such cases, operations can be stabilised by either increasing the size of CIN of decreasing the size
of CL.
3. Please ensure that output current (IOUT) is less than Pd ÷ (VIN - VOUT) and does not exceed the
stipulated continuous total power dissipation value (Pd) for the package.
