LF47CV [STMicroelectronics]

LF47CV Description

The LF47CV is a very low drop regulator available in TO-220, TO-220FP, DPAK, and PPAK packages and in a wide range of output voltages. The low drop voltage (0.45 V) and low quiescent current make it particularly suitable for low-noise, low-power applications and especially in battery-powered systems. In the 5-pin configuration (PPAK) a shutdown logic control function is available (pin 2, 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.
