This document introduces the features and characteristics of the SLVS521B regulator, including the use of the NanoStar chip scale package, fixed/adjustable versions, output tolerance of 0.75% (A grade)/1.25% (standard grade), ultra-low dropout, wide VIN range, low IQ, shutdown current, fast transient response, overcurrent and thermal protection, and high peak current capability
The LP2981 family of regulators offers exceptional performance for portable and nonportable applications. It is available in both fixed-output voltages (ranging from 1.25V to 5V) and an adjustable version. The device features a typical dropout voltage of 200 mV at full load, low quiescent current, and includes shutdown functionality that reduces consumption to 0.01 µA.
| Load Current | 100 mA |
|---|---|
| Output Tolerance (A Grade) | 0.75% |
| Output Tolerance (Standard Grade) | 1.25% |
| Dropout Voltage (Full Load) | 200 mV |
The LP2981 is capable of delivering a continuous load current of 100 mA.
The regulator has a typical dropout of 200 mV when operating at a 100-mA load.
When the ON/OFF pin is pulled low, the regulator consumes only 0.01 µA.
