A6516 series are high precise, low power consumption, high voltage input, positive voltage regulators manufactured using CMOS and laser trimming technologies. The A6516 consists of a current limiter circuit, a driver transistor, a precision reference voltage and a correction circuit. Output voltage is selectable in 0.1V steps from 1.2V to 5.0V. The series are also compatible with low ESR ceramic capacitors which give added output stability .Since the current limiter circuit is built-in, the IC is protected against overshoot currents at such times of output shorts etc.
