Very low voltage drop regulator with suppression function

Technology Cover
Data di Pubblicazione: 2023-01-01, STMicroelectronics

The LEXX is a very low voltage drop regulator available in SO-8, TO-92 packages and a wide range of output voltages. The extremely low step-down (0.2V) and low static current make it particularly suitable for low-noise, low-power applications and battery-powered systems. The device is compatible with the L78L series. Also, in the 8-pin configuration (SO-8), it uses shutdown logic control (pin 5,TTL compatible).

This means that when the device is used as a local voltage regulator, a portion of the board can be placed on standby, thus reducing the total power consumption. In a three-terminal configuration (TO-92), the device is always on. It requires stability of 2.2μF capacitance, reducing component size and cost
