Description

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

low-dropout voltage regulator supporting an input

voltage range from 2.5V to 16V (for new chip) and

up to 150mA of load current. The LP2985 supports an

output range of 1.2V to 5.0V (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 30µVRMS (with 10nF bypass

capacitors) and wide bandwidth PSRR performance

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

help attenuate the switching frequency of an upstream

DC/DC converter and minimize post regulator filtering.

The new chip provides internal soft-start mechanism

to reduce inrush current during start up, thus

minimizing input capacitance. Standard protection

features, such as overcurrent and overtemperature

protection, are also included.

The LP2985 is available in a 5-pin 2.9mm × 2.8mm

SOT-23 (DBV) package
