KF55 Datasheet | STMicroelectronics

DESCRIPTION The KF00 series are very Low Drop regulators available in 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. SCHEMATIC DIAGRAM A Shutdown Logic Control function is available (pin 5, TTL patible). 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.
