Overview
ISSUED DATE :2003/08/02 REVISED DATE :2006/06/05C G M 111 7 A Description 1A Low Dropout Positive Adjustable or Fixed-Mode Regulator The GM1117A is a low dropout at positive adjustable or fixed-mode regulator with minimum of 1A output current capability.
The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 3.
3V logic supply.
GM1117A is also well suited for other applications such as VGA cards.
GM1117A is guaranteed to have lower than 1.
4V dropout at full load current making it ideal to provide well-regulated outputs of 1.
25 to 5.
0 with 6.
4V to 12V input supply.

Typical Circuit GM1117A Page: 1/4 ISSUED DATE :2003/08/02 REVISED DATE :2006/06/05C Block Diagram Pin Descriptions Name Adj (GND) Vout Vin O I I/O Pin# 1 2 3 Function A resistor divider from this pin to the Vout pin and ground sets the output voltage (Ground only for fixed mode) The output of the regulator.
A minimum of 10uF capacitor must be connected from this pin to ground to insure stability.
The input pin of regulator.
Typically a large storage capacitor is connected from this pin to ground to insure that the input voltage does not sag below the minimum dropout voltage during the load transient response.
This pin must always be 1.
3V higher than Vout in order for the device to regulate properly.
