Description
General part information
LP2981 Series
The LP2981 and LP2981A (LP2981x) are fixed-output, low-dropout (LDO) voltage regulators supporting an input voltage range from 2.5V to 16V (for new chip only) and up to 100mA of load current. The LP2981x support an output range of 1.2V to 5.0V (new chip).
Additionally, the LP2981x (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.
