Product Summary

The LP2954AIT is a 5V and Adjustable Micropower Low-Dropout 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). The quiescent current increases only slightly at dropout (120 µA typical), which prolongs battery life. The applications of the LP2954AIT are High-efficiency linear regulator, Low dropout battery-powered regulator.

Parametrics

LP2954AIT absolute maximum ratings: (1)Operating Junction Temperature: −40˚C to +125˚C; (2)Storage Temperature Range: −65˚C to +150˚C; (3)Lead Temperature(Soldering, 5 seconds): 260˚C; (4)Power Dissipation: Internally Limited; (5)Input Supply Voltage: −20V to +30V; (6)ESD Rating: 2 kV.

Features

LP2954AIT features: (1)5V output within 1.2% over temperature (A grade); (2)Adjustable 1.23 to 29V output voltage available; (3)Guaranteed 250 mA output current; (4)Extremely low quiescent current; (5)Low dropout voltage; (6)Reverse battery protection; (7)Extremely tight line and load regulation; (8)Very low temperature coefficient; (9)Current and thermal limiting; (10)Pin compatible with LM2940 and LM340 (5V version only); (11)Adjustable version adds error flag to warn of output drop and a logic-controlled shutdown.
