AiT Semiconductor Inc. www.ait-ic.com A6516 LOW DROPOUT VOL TAGE REGULATOR 16V , 500mA, LOW IQ, CMOS LDO REV1.1 - MAR 2017 RELEASED, JUL 2020 UPDATED - - 1 - DESCRIPTION FEATURES A6516 series are high precise, low power consumption, high voltage input, positive voltage regulators manufactured using CMOS and laser trimming technologies. The A6 516 consists of a current limiter circuit, a driver transistor, a pr ecision 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. The A6516 is available in SOT-25 package.

Its application circuit is very simple, which only needs two outside capacitors. It is composed of these modules: high accuracy voltage reference, current limit circuit, error amplifier, output driver and power transistor. Current Limit module can keep chip and power system away from danger when load current is more than 500mA. A6516 uses trimming technique to assure the accuracy of output value within±2%, at the same time, temperature compensation is elaborately considered in this chip, which makes A6516’s temperature coefficient within ±100ppm/℃。
