LE33CD-TR (STMICROELECTRONICS)

The LE33CD-TR is a Low Drop-out Voltage Regulator with inhibits function and 3.3V output voltage. 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 3-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.
