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
, 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.
