LP2954 Product details

Description

The LP2954 is a 5V micropower voltage regulator 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)..

Features

n 5V output within 1.2% over temperature (A grade) n Adjustable 1.23 to 29V output voltage available (LP2954IM and LP2954AIM) n Guaranteed 250 mA output current n Extremely low quiescent current n Low dropout voltage n Reverse battery protection n Extremely tight line and load regulation n Very low temperature coefficient n Current and thermal limiting n Pin compatible with LM2940 and LM340 (5V version only) n Adjustable version adds error flag to warn of output drop and a logic-controlled shutd.
