AMS6209
■GENERAL DESCRIPTION
The AMS6209 series are highly precise, low power 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 AMS6209 consists of a current limiter circuit, a driver transistor, a precision reference voltage and an error correction circuit.
The series is compatible with low ESR ceramic capacitors. The currrent 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 3.0V to
5.0V.
SOT-23, SOT-89, TO-92 are available.
