ADP1111AR-12-REEL             DESCRIPTION

The ADP1111 is part of a familyofstep-up/step-down switch- ing regulators that operates from an input voltage supply of2V to 12 V in step-up mode and up to 30 Vin step-down mode. The ADP1111 can be programmed to operate in step-up/step- down or inverting applications with only 3 external components. The fixed outputs are 3.3 V5 Vand 12 Vand an adjustable version is also available.The ADP1111 can deliver 100 mA at5 V from a 3 V input in step-up modeor it can deliver200mA at 5 V from a 12 Vinput in step-down mode.
