KF8177 series are a highly precise， lower consumption, 3 terminal,positive voltage regulators manufactured using CMOS and laser trimming technologies. The series provides large currents with a significantly small dropout voltage .
The KF8177 consists of a current limiter circuit, a driver transistor, a precision reference voltage and an error correction circuilt. The series is compatible with low ESR ceramic capacitors. The current limiter's foldback circuit operates as a short circuit protection as well as the output current limiter for the output pin. Output voltages are internally by laser trimming technologies. It is selectable in 0.1V increments within a range of 1.2V to 5.0V. KF8177 series are available in SOT-23、SOT23- 3and SOT89 packages.
