LP2980-N - Texas Instruments

LP2980-N Micropower 50-mA Ultra-Low-Dropout Regulator

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-vol.
