Product overview

Description

The LEXX is a very low-dropout voltage regulator available in SO-8, TO-92 packages and over a wide range of output voltages.

The very low-dropout voltage (0.2 V) and low quiescent current make it particularly suitable for low-noise, low-power applications and in battery-powered systems.

This device is pin-to-pin compatible with the L78L series. Furthermore, in the 8-pin configuration (SO-8), it uses a shutdown logic control (pin 5, TTL compatible). This means that when the device is used as a local regulator, a part of the board can be put in standby, decreasing the total power consumption. In the three-terminal configuration (TO-92), the device is always in on-state. It requires a 2.2 µF capacitor for stability, reducing the component size and cost.

  • All features

    • Very low-dropout voltage (0.2 V typ.)
    • Very low quiescent current (typ. 50 µA in OFF mode, 0.5 mA in ON mode, no load)
    • Output current up to 100 mA
    • Output voltages: 3 V, 3.3 V, 4.5 V, 5 V, 8 V
    • Internal current and thermal limit
    • Small 2.2 µF capacitor for stability
    • Available in ±1% (A) or ±2% (C) selection at 25 °C
    • Supply voltage rejection: 80 dB (typ.)
    • Temperature range: -40 to 125 °C
