250-mA, 16-V, low-dropout voltage regulator with enable

The LP2992 is a fixed-output,

wide-input, low-noise, low-dropout voltage regulator supporting an input voltage

range from 2.5V to 16V and up to 250mA of load current. The LP2992 supports an

output range of 1.2V to 5.0V (new chip).

Additionally, the LP2992 (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 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 LP2992 is available in a 5-pin

2.9mm × 2.8mm SOT-23 (DBV) package.
