DESCRIPTION
Active-Low Shutdown Input. A logic low reduces the supply current to less than 1µA.
Connect to IN for normal operation.
Ground. This pin also functions as a heatsink. Solder to large pads or the circuit board
ground plane to maximize thermal dissipation.
Regulator Input. Supply voltage can range from +2.5V to +5.5V. Bypass with 1µF to GND
Regulator Output. Fixed or adjustable from 1.25V to +5.5V. Sources up to 150mA.
Bypass with a 1µF, ï¼0.2⦠typical ESR capacitor to GND.
Feedback Input for Setting the Output Voltage. Connect to GND to set the output voltage
to the preset voltage. Connect to an external resistor divider for adjustable-output
operation.
