SNVS764N –JANUARY 2000–REVISED MAY 2013

LP2950-N/LP2951-N Series of Adjustable Micropower Voltage Regulators

Check for Samples: LP2950-N, LP2951-N

FEATURES

DESCRIPTION

The LP2950-N and LP2951-N are micropower

•

5V, 3V, and 3.3V Versions Available

High Accuracy Output Voltage

Ensured 100 mA Output Current

Extremely Low Quiescent Current

Low Dropout Voltage

voltage regulators with very low quiescent current (75

μA typ.) and very low dropout voltage (typ. 40 mV at

light loads and 380 mV at 100 mA). They are ideally

suited for use in battery-powered systems.

Furthermore, the quiescent current of the LP2950-

N/LP2951-N increases only slightly in dropout,

prolonging battery life.

Extremely Tight Load and Line Regulation

Very Low Temperature Coefficient

Use as Regulator or Reference

Needs Minimum Capacitance for Stability

Current and Thermal Limiting

The LP2950-N-5.0 is available in the surface-mount

PFM package, and in the popular 3-pin TO-92

package for pin-compatibility with older 5V regulators.

The 8-lead LP2951-N is available in plastic, ceramic

dual-in-line, WSON, or metal can packages and

offers additional system functions.

Stable With Low-ESR Output Capacitors (10

mΩ to 6Ω)

One such 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.

LP2951-N VERSIONS ONLY

•

Error Flag Warns of Output Dropout

Logic-Controlled Electronic Shutdown

Output Programmable From 1.24 to 29V

Careful design of the LP2950-N/LP2951-N has

minimized all contributions to the error budget. This

includes a tight initial tolerance (.5% typ.), extremely

good load and line regulation (.05% typ.) and a very

low output voltage temperature coefficient, making

the part useful as a low-power voltage reference.
