Description
GM6250 combine high accuracy with very low power con-
Maximum output current 250mA (within
sumption, and provides high output current even when the
application requires extremely low input-output voltage dif-
ferential.
maximum power dissipation)
Output voltage: from 1.8 V to 5.0V in 0.1V
increments
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.
Output voltage ±2%

DIRECTIONS FOR USAGE
Notes on Usage
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 (C )
IN
of at least 1µF.
With a large output current, operations can be stabilised by increasing capacitor size (C ). If C is
IN IN
small and capacitor size (C ) is increased, there is a possibility of oscillation due to input impedance.
L
In such cases, operations can be stabilised by either increasing the size of C or decreasing the size of C .

CALCULATING POWER DISSIPATION
The GM6250 series precision linear regulators include thermal shutdown and current limit circuitry to
protect the devices. However, high power regulators normally operate at high junction temperatures so it
is important to calculate the power dissipation and junction temperatures accurately to be sure that you
use and adequate heat sink.
The thermal characteristics of an IC depend four factors:
1. Maximum Ambient Temperature T (°C)
A
2. Power Dissipation P (Watts)
D
3. Maximum Junction Temperature T (°C)
J
4. Thermal Resistance Junction to ambient R
(°C/W)
JA
Q
These relationship of these four factors is expressed by equation (1): T = T + P X R
J A D
QJA
Maximum ambient temperature and power dissipation are determined by the design while the maximum
junction temperature and thermal resistance depend on the manufacturer and the package type.
