LE50AB VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT

The LExxAB and LExxC are very low dropout voltage regulators available in SO-8 and TO-92 packages and over a wide range of output voltages.

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

These devices are pin-to-pin compatible with the older L78Lxx series. Furthermore, in the 8-pin configuration (SO-8) they employ 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 even more total power consumption. In the three-terminal configuration (TO-92) the device is always in the ON state, maintaining the same electrical performance. It requires only a 2.2 μF capacitor for stability, reducing component size and cost
