LP2951JAN Series of Adjustable Micropower Voltage Regulators

Check for Samples: LP2951JAN

FEATURES

DESCRIPTION

The LP2951 is a micropower voltage regulator with

very low quiescent current (75μA typ.) and very low

dropout voltage (typ. 40mV at light loads and 380mV

at 100mA). It is ideally suited for use in battery-

powered systems. Furthermore, the quiescent current

increases only slightly in dropout, prolonging battery

life.

High Accuracy Output Voltage

Ensured 100mA Output Current

Extremely Low Quiescent Current

Low Dropout Voltage

Extremely Tight Load and Line Regulation

Very Low Temperature Coefficient

Use as Regulator or Reference

Needs Minimum Capacitance for Stability

Current and Thermal Limiting

An additional feature is an error flag output which

warns of a low output voltage, often due to falling

batteries on the input. It may be used for a power-on

reset. A second feature is the logic-compatible

shutdown input which enables the regulator to be

switched on and off. Also, the part may be pin-

strapped for a 5V, 3V, or 3.3V output (depending on

the version), or programmed from 1.24V to 29V with

an external pair of resistors.

Stable with Low-ESR Output Capacitors (10mΩ

to 6Ω)

•

Error Flag Warns of Output Dropout

Logic-Controlled Electronic Shutdown

Output Programmable from 1.24 to 29V

Careful design of the LP2951 has minimized all

contributions to the error budget. This includes a tight

initial tolerance (0.5% typ.), extremely good load and

line regulation (0.05% typ.) and a very low output

voltage temperature coefficient, making the part

useful as a low-power voltage reference.
