LE33CZ-AP

LE33CZ-AP is a very low-dropout voltage regulator with inhibit function. The very low dropout voltage (0.2V) and low quiescent current make it particularly suitable for low-noise, low-power applications and battery-powered systems. This device is pin-to-pin compatible with the L78L series. Furthermore, the 8-pin configuration (SO-8), 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 on standby, decreasing the total power consumption. In the three-terminal configuration (TO-92), the device is always in on-state. It requires a 2.2µF capacitor for stability, reducing the component size and cost.
