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.

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 LP2982 is available in a 5-pin 2.9-mm × 2.8-mm SOT-23 (DBV) package.
