L4931CZ33-AP

STMICROELECTRONICS  L4931CZ33-AP  LDO Voltage Regulator - Fixed, 20V input, 3.3Vnom/250 mA out, TO-92-3 新

The is a very low drop Voltage Regulator with inhibit function. The very low drop voltage 0.4V and the very low quiescent current make it particularly suitable for low noise, low power applications and especially in battery-powered systems. A TTL compatible shutdown logic control function is available in PPAK and SO-8 packages. This means that when the device is used as a local regulator, a part of the board can be put in standby mode, decreasing the total power consumption. It requires only a 2.2µF capacitor for stability allowing space.
