3 Description
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.
