This document describes the LExxAB and LExxC series of very low dropout voltage regulators available in SO-8 and TO-92 packages. These devices are designed for low-noise, low-power applications, particularly in battery-powered systems, offering output voltages of 3V, 3.3V, 4.5V, 5V, and 8V.
| Dropout voltage | 0.2 V typ. |
|---|---|
| Output current | up to 100 mA |
| Output voltages | 3V, 3.3V, 4.5V, 5V, 8V |
| Quiescent current (ON mode) | 0.5 mA |
| Quiescent current (OFF mode) | 50 µA |
| Supply voltage rejection | 80 dB typ. |

The typical dropout voltage is 0.2 V.
Yes, the 8-pin SO-8 configuration employs a shutdown logic control on pin 5.
A small 2.2 µF capacitor is required for stability.
