3A Low Dropout Voltage Regulator
DEC. 2009
Product Description
The GS1085L is a lo w drop voltage regulator able
to provid e up to 3A output current. T he dropo ut
voltage of the device is gu aranteed at a m aximum
1.3V at the maximum output current, decreasing at
lower loads.
The GS1085L is pin co mpatible with older
3-terminal adj ustable regul ators, but has better
performances in term of drop and output tolerance.
Features
Three Terminal Adjustable or Fixed Output
Voltages 1.5V, 1.8V, 2.5V, 3.3V and 5V
Guaranteed Output Current up to 3A
Typical Dropout 1.3V (at 3A)
Output Tolerance: ±2% at 25 ºC
W ind Operating Temperature Range: -40 ºC
to 125 ºC
Package Available: TO-220, TO-263,
T O-252, and SOT-223
Applications
Post Regulators for Switching Supply
Batter y-Powered Circuitry
Low Voltage Logic Supplies
High efficiency linear regulators
Adjustable power supply
