The LP2980-N is a fixed-output, wide-input, low-dropout (LDO) voltage regulator supporting an input voltage range from 2.5 V to 16 V and up to 50 mA of load current. The LP2980-N supports an output range of 1.2 V to 5.0 V (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 75 dB at 1 kHz and 45 dB at 1 MHz 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, 2.9-mm × 1.6-mm SOT-23 (DBV) package.
