The KFxxB series is a very low dropout regulator from STMicroelectronics, available in SO-8 and DPAK packages. It has a wide range of output voltages from 1.5V to 8V and can output up to 500mA. It has very low static current and switching losses, making it suitable for low noise, low power applications. It can also be used in battery powered systems.
The KFxxB series are very low dropout voltage regulators available in SO-8 and DPAK packages. They feature a very low dropout voltage of 0.4 V and very low quiescent current, making them suitable for low noise, low power, and battery-powered applications. The series includes output voltages of 1.5 V, 2.5 V, 3.3 V, 4 V, 5 V, and 8 V.
