LP2981 Overview
The LP2981 is a fixed-output, low-dropout (LDO) voltage regulator supporting an input voltage range from 2.5 V to 16 V (for new chip only) and up to 100 mA of load current. The LP2981 supports an output range of 1.2 V to 5.0 V (new chip). Additionally, the LP2981 (new chip) has a 1% output accuracy across load and temperature that can meet the needs of low-voltage microcontrollers (MCUs) and processors.
