SNVS095F –MAY 2004–REVISED MARCH 2015

LP295x Adjustable Micropower Low-Dropout Voltage Regulators

1 Features

3 Description

The LP2952 and LP2953 are micropower voltage

•

2.3-V to 30-V Input Voltage Range

Output Voltage Adjusts from 1.23 V to 29 V

250-mA Output Current

regulators with very low quiescent current (130 μA

typical at 1-mA load) and very low dropout voltage

(typically 60 mV at light load and 470 mV at 250-mA

load current). They are ideally suited for battery-

powered systems. Furthermore, the quiescent current

increases only slightly at dropout, which prolongs

battery life.

Extremely Low Quiescent Current

Low Dropout Voltage

Extremely Tight Line and Load Regulation

Very Low Temperature Coefficient

Current and Thermal Limiting

The LP2952 and LP2953 retain all the desirable

characteristics of the LP2951, but offer increased

output current, additional features, and an improved

shutdown function.

Reverse Battery-Input Protection

50-mA (Typical) Automatic Output Discharge

LP2953 Versions Only

The automatic output discharge pulls the output down

quickly when the shutdown is activated.

–

Auxiliary Comparator Included With CMOS-

and TTL-Compatible Output Levels. Can Be

Used for Fault Detection, Low-Input Line

Detection, and so on.

The error flag goes low if the output voltage drops out

of regulation.

Reverse battery-input protection is provided.

The internal voltage reference is made available for

external use, providing a low temperature coefficient

(20 ppm/°C) reference with very good line (0.03%)

and load (0.04%) regulation.

2 Applications

•

High-Efficiency Linear Regulator

Regulator With Undervoltage Shutdown

Low-Dropout Battery-Powered Regulator

Snap-ON/Snap-OFF Regulator
