The LP2980-N is a fixed-output, wide-input, low-dropout (LDO) voltage regulator supporting an input voltage range from 2.5V to 16V and up to 50mA of load current. The LP2980-N supports an output range of 1.2V to 5.0V (new chip).

Additionally, the LP2980-N (new chip) has a 1% output accuracy across load and temperature that can meet the needs of low-voltage microcontrollers (MCUs) and processors.

In the new chip, wide bandwidth PSRR performance is 75dB at 1kHz and 45dB at 1MHz to 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 LP2980-N is available in a 5-pin, 2.9mm × 1.6mm SOT-23 (DBV) package.
