KF33BD Datasheet PDF - ST Microelectronics

●DESCRIPTION

●The KF00 series are very Low Drop regulators availablein SO-8 package and in a wide range of output voltages.

●The very Low Drop voltage (0.4V) and the very low quiescent current make them particularly suitable for Low Noise, Low Power applications and specially in battery powered systems.

●A Shutdown Logic Control function is available (pin 5, TTL compatible). This means that when the device is used as a local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. It requires only a 2.2 µF capacitor for stability allowing space and cost saving.
