3 Description

The LP2985 is a fixed-output, wide-input, low-noise,

low-dropout voltage regulator supporting an input

voltage range from 2.5 V to 16 V and up to 150 mA of

load current. The LP2985 supports an output range of

1.2 V to 5.0 V (for new chip).

Additionally, the LP2985 (new chip) has a 1 output

accuracy across load, and temperature that can meet

the needs of low-voltage microcontrollers (MCUs) and

processors.

Low output noise of 30 μVRMS (with 10-nF bypass

capacitors) and wide bandwidth PSRR performance

of greater than 70 dB at 1 kHz and 40 dB at 1 MHz

help attenuate the switching frequency of an upstream

DC/DC converter and minimize post regulator filtering.

The internal soft-start time and current limit protection

reduce inrush current during start up, thus minimizing

input capacitance. Standard protection features, such

as overcurrent and overtemperature protection, are

included.

The LP2985 is available in a 5-pin 2.9-mm × 1.6-mm

SOT-23 (DBV) package.
