Overview
UNISONIC TECHNOLOGIES CO.
, LTD LR2126 1A FAST ULTRA LOW DROPOUT LINEAR REGULATOR „ DESCRIPTION The UTC LR2126 operate from a +2.
5V ~ +6.
0V input supply as fast ultra low-dropout linear regulators.
Wide output voltage range options are available.
The fast response characteristic to make UTC LR2126 suitable for low voltage microprocessor application.
The low quiescent current operation and low dropout quality caused by the CMOS process.
The UTC LR2126 has ultra low dropout voltage 300mV at 1A load current typically.
The ground pin current is typically 60uA at 1mA load current.
Output Voltage Precision: Multiple output voltage options are available and ranging from 1.
2V ~ 5.
0V at room temperature with a guaranteed accuracy of ±1.
5%, and ±3.
0% when varying line, load and temperature.
„ FEATURES * Ultra Low Dropout Voltage * Low Ground Pin Current * 0.
04% Load Regulation * The Guaranteed Output Current is 1A DC * Output Voltage Accuracy ± 1.
5% * Low Output Capacitor Required * Over temperature Protection And Over current Protection „ ORDERING INFORMATION Ordering Number Lead Free Halogen Free LR2126L-xx-AB5-R LR2126G-xx-AB5-R Package SOT-89-5 CMOS IC Packing Tape Reel www.

2 GND Ground.
3 ADJ Adjustable voltage version only – a resistor divider from this pin to the OUT pin and ground sets the output voltage.
4 IN Input voltage.
5 OUT Output voltage.
Note: The NC pin is electrically open.
The NC pin can be connected to VIN or GND.
