LP2980-ADJ

LP2980-ADJ Micropower SOT, 50 mA Ultra Low-Dropout Adjustable Voltage Regulator April 2000 LP2980-ADJ Micropower SOT, 50 mA Ultra Low-Dropout Adjustable Voltage Regulator General Description The LP2980-ADJ is a 50 mA adjustable voltage regulator designed to provide ultra low dropout in battery powered applications. Using an optimized VIP™ (vertically Integrated PNP) process, the LP2980-ADJ delivers unequalled performance in all specifications critical to battery-powered designs: Adjustable Output: output voltage can be set from 1.23V to 15V. Precision Reference: 0.75% tolerance. Dropout Voltage: typically 120 mV @ 50 mA load, and 7 mV @ 1 mA load. Ground Pin Current: typically 320 µA @ 50 mA load, and 80 µA @ 1 mA load. Sleep Mode: less than 1 µA quiescent current when on/off pin is pulled low. Smallest Possible Size: SOT-23 package uses minimum board space.
