R1510 Series
36V Input Automatic ECO Mode Shift 300mA Voltage Regulator with VD
The R1510 Series are CMOS-based auto mode switching voltage regulators featuring 300mA output current with voltage detector. The R1510 has a 36V maximum input voltage VR and VD on a single chip. As the voltage regulator is an automatic mode shift type, the operation can switch automatically to a fast response mode or a low power mode of the ECO function according to output current. (Automatic switching to fast response mode under IOUT > 12mA conditions or to low power mode under IOUT < 3mA conditions.)
R1510 with a built-in voltage detector is available in four versions. The differences between these versions are in CE pin, points to be detected, and delay function.
