LP2985
Micropower 150 mA Low-Noise Ultra Low-Dropout
Regulator
Designed for Use with Very Low ESR Output Capacitors
General Description
The LP2985 is a 150 mA, fixed-output voltage regulator de-
signed to provide ultra low-dropout and low noise in battery
powered applications.
Using an optimized VIP(Vertically Integrated PNP) pro-
cess, the LP2985 delivers unequalled performance in all
specifications critical to battery-powered designs:
Dropout Voltage: Typically 300 mV @ 150 mA load, and
7 mV @ 1 mA load.
Ground Pin Current: Typically 850 µA @ 150 mA load, and
75 µA @ 1 mA load.
Enhanced Stability: The LP2985 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 1 µA quiescent current when
ON/OFF pin is pulled low.
Smallest Possible Size: SOT-23 and micro SMD packages
use absolute minimum board space.
Precision Output: 1% tolerance output voltages available
(A grade).
Low Noise: By adding a 10 nF bypass capacitor, output
noise can be reduced to 30 µV (typical).
Multiple voltage options, from 2.5V to 5.0V, are available as
standard products. Consult factory for custom voltages.

Basic Application Circuit
DS100140-2
*ON/OFF input must be actively terminated. Tie to VIN if this function is not to be used.
**Minimum capacitance is shown to ensure stability (may be increased without limit). Ceramic capacitor required for output (see Application Hints).
***Reduces output noise (may be omitted if application is not noise critical). Use ceramic or film type with very low leakage current (see Application Hints).
