3 Description
The LP2980-N is a fixed-output, wide-input, lowdropout (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 kH...
