LP2954 SMD 8pin Adjustable Micropower LDO Regulator

Description

The LP2954 is an adjustable micropower LDO with very low quiescent current (90 μA typical at 1-mA load) and very low dropout voltage (typically 60 mV at light loads and 470 mV at 250-mA load current). The quiescent current increases only slightly at dropout (120 μA typical), which prolongs battery life. LP2954 is provided in an 8-pin, small outline SOIC package. The adjustable version also provides a resistor network which can be pin strapped to set the output to any voltage from to 1.23 V to 29 V.
