Nisshinbo Micro Devices Inc. R1510S008D-E2-FE

The R1510S is a voltage regulator (LDO) IC with a voltage detector (VD) featuring 300 mA 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 highspeed mode when IOU = 12 mA (Typ.), and switch from high-speed mode to low-power consumption mode when IOU = 3 mA (Typ.). 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 is Nch open drain. The versions for the IC are selectable from A version (CE, VIN Detector), B version (SENSE Detector), C version (Release Delay Circuit, VIN Detector), and D version (Release Delay Circuit, VOUT Detector).
