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.
