Description
General part information
LP2982 Series
The LP2982 is a fixed-output, wide-input, low-noise, low-dropout voltage regulator supporting an input voltage range from 2.5 V to 16 V (for new chip) and up to 50 mA of load current. The LP2982 supports an output range of 1.2 V to 5.0 V (for new chip).
Additionally, the LP2982 (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 µV RMS (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.
