The KFxx series KF15B are very low drop regulators available in SO-8 package and in a wide range of output voltages.
The very low drop voltage (0.4 V) 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, KF15B is possible to put a part of the board in standby, decreasing the total power consumption. KF15B requires only a 2.2 F capacitor for stability allowing space and cost saving.
