100mA Low -Dropou t Vol tag e Regu l ato r
Description
The GSCLP2951 is a low power voltage regulator. This device excellent choice for use in battery powered
application such as cordless telephone, radio control systems, and portable computers. The device features
very low quiescent current (75uA Typ.) and very low drop output voltage (Typ. 40mV at light load and 380mV at
100mA). This includes a tight initial tolerance of 0.5% typ., extremely good load and line regulation of 0.05%
typ., and very low output temperature coefficient, marking the part useful as a low-power voltage reference.
The error flag output feature is used as power-on reset for warns of a low output voltage, due to following
batteries on input. Other feature is the logic-compatible shutdown input which enable the regulator to be
switched on and off. The regulator output voltage may be pin-strapped for fixed output voltage or programmed
from 1.24V to 29V with external pair of resistors.
