105°C Operation, 66 V Input, 200 mA Voltage Regulator S-1231 Series

Product Overview Standard Circuit Example: VOUT internally set Standard Circuit Example: VOUT externally set TO-252-5S(A) (VA005-A) HSOP-8A (FH008-A) HTMSOP-8 (FP008-A)

This IC developed by using high-withstand voltage CMOS process technology, is a positive voltage regulator with a high-withstand voltage, low current consumption and high-accuracy output voltage.
It has a high operation voltage of 66 V, making it compatible with 12 V, 24 V, and 48 V battery systems, and it can be operated at a low consumption current of 2.0 μA typ. It also features a built-in overcurrent protection circuit to limit overcurrent of the output transistor, a built-in thermal shutdown circuit to limit heat, and a built-in open-loop protection circuit to control output voltage overvoltage.
