LP2951

100 mA Low-Dropout Voltage Regulator

Features

General Description

• High Accuracy 5V, Guaranteed 100 mA Output

• Extremely Low Quiescent Current

• Low-Dropout Voltage

The LP2951 is micropower voltage regulators with very

low dropout voltage (typically 40 mV at light loads and

380 mV at 100 mA), and very low quiescent current

(75 μA typical). The quiescent current of the LP2951

increases only slightly in dropout, thus prolonging

battery life. This feature, among others, makes the

LP2951 ideally suited for use in battery-powered

systems.

• Extremely Tight Load and Line Regulation

• Very Low Temperature Coefficient

• Use as Regulator or Reference

• Needs Only 1 μF for Stability

• Current and Thermal Limiting

Available system functions, such as programmable

output voltage and logic-controlled shutdown, are

available as well.

• Error Flag Warns of Output Dropout

• Logic-Controlled Electronic Shutdown

• Output Programmable from 1.24V to 29V

Additional features available with the LP2951 also

include an error flag output that warns of a low output

voltage, which is often due to failing batteries on the

input. This may also be used as a power-on reset. A

logic-compatible shutdown input is also available which

enables the regulator to be switched on and off. This

part may also be pin-strapped for a 5V output, or

programmed from 1.24V to 29V with the use of two

external resistors.

Applications

• Automotive Electronics

• Voltage Reference

• Avionics

The LP2951 is available as either a -02 or -03 version.

The -02 and -03 versions are guaranteed for junction

temperatures from -40°C to +125°C; the -02 version

has a tighter output and reference voltage specification

range over temperature.

The LP2951 have a tight initial tolerance (0.5% typical),

a very low output voltage temperature coefficient which

allows use as a low-power voltage reference, and

extremely good load and line regulation (0.05%

typical). This greatly reduces the error in the overall

circuit, and is the result of careful design techniques

and process control.
