LP2967

Dual Micropower 150 mA Low-Dropout Regulator in

micro SMD Package

General Description

The LP2967 is a 150 mA, dual fixed-output voltage regulator

designed to provide ultra low-dropout and low noise in bat-

tery powered applications.

Using an optimized VIP (Vertically Integrated PNP) process,

the LP2967 delivers unequalled performance in all specifi-

cations critical to battery powered designs:

Dropout Voltage: Typically 240 mV at 150 mA load, and

6 mV at 1 mA load for each output.

Ground Pin Current: Typically 1 mA at 150 mA load, and

200 µA at 1 mA load for each output.

Enhanced Stability: The LP2967 is stable with output ca-

pacitor ESR as low as 5 m

Ω, which allows the use of ceramic

capacitors on the output.

Sleep Mode: Less than 2 µA quiescent current when SD

pins are pulled low.

Smallest Possible Size: micro SMD package uses absolute

minimum board space.

Precision Output: 1.25% tolerance.

Low Noise: By adding a 100 nF bypass capacitor, output

noise can be reduced to 30 µV (typical).

Multiple voltage options, from 1.8V to 5.0V, are available.

Consult factory for custom voltages.
