OUTLINE

The R1510S is a voltage regulator (LDO) IC with a voltage detector (VD) featuring 300mA output current that

is developed with CMOS process technology. Each IC is equipped with a voltage detector and a regulator that

can provide the maximum 36V of operating voltage. This device has ECO function, which achieves low-power

consumption and high-speed transient response by switching the IC to low-power consumption mode at light load

condition and switching to high-speed mode at heavy load condition.

The switching point is internally fixed inside the IC. The IC switches from low-power consumption mode to high-

Each IC is composed of a reference voltage unit, an error amplifier, a resistor network for setting output voltage,

an output current limit circuit for preventing overcurrent destruction, and a thermal shutdown circuit. The output

voltage and the detector threshold are internally fixed inside the IC.

The output voltage accuracy is ±1.6% and the detector threshold accuracy is ±1.7%. The output voltage type
