G950
Global Mixed-mode Technology Inc.
2.5V 1A Regulator
Features
General Description
„Output current in excess of 1A
„Output voltage accuracy +3%/-1%
„Quiescent current, typically 600µA
„Internal short circuit current limit
„Internal over temperature protection
The G950 positive 2.5V voltage regulator features
the ability to source 1A of output current. The typical
quiescent current is 0.6mA.
Familiar regulator features such as over temperature and over current protection circuits are provided to prevent it from being damaged by abnormal operating conditions.

Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating
Conditions are conditions under which the device functions but the specifications might not be guaranteed. For
guaranteed specifications and test conditions see the Electrical Characteristics.
Note2: The maximum power dissipation is a function of the maximum junction temperature, TJmax ; total thermal resistance, θJA, and ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is Tjmax-TA / θJA. If this dissipation is exceeded, the die temperature will rise above 150°C and IC
will go into thermal shutdown. For the G950 in SOT 223 package, θJA is 156°C/W; in TO 263 package, θJA
is 75°C/W, and in the TO 252 package, θJA is 125°C/W (See recommend minimum footprint). The safe
operation in SOT 223,TO 252 & TO 263 package, it can see “Typical Performance Characteristics” (Safe
Operating Area).
Note3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
Note4: The type of output capacitor should be tantalum or aluminum.
Definitions
Load Regulation
The change in output voltage for a change in load
current at constant chip temperature. The measurement is made under conditions of low dissipation or by
using pulse techniques such that average chip temperature is not significantly affected.
Dropout Voltage
The input/output Voltage differential at which the
regulator output no longer maintains regulation against
further reductions in input voltage. Measured when the
output drops 100mV below its nominal value. Dropout
voltage is affected by junction temperature, load current and minimum input supply requirements.
Maximum Power Dissipation
The maximum total device dissipation for which the
regulator will operate within specifications.
Line Regulation
The change in output voltage for a change in input
voltage. The measurement is made under conditions
of low dissipation or by using pulse techniques such
that average chip temperature is not significantly affected.
Quiescent Bias Current
Current which is used to operate the regulator chip
and is not delivered to the load.
