10 V, 5.0 V Low Dropout (LDO) Dual Voltage Regulator with ENABLEbar

The CS8147 is a 10 V/5.0 V dual out- put linear regulator. The 10 V +/- 5.0 V% output sources 500mA and the 5.0 V +/-3% output sources 70mA. The secondary output is inherently stable and does not require an external capacitor.

The on board ENABLEbar function controls the regulator's two outputs. When ENABLEbar is high, the regulator is placed in SLEEP mode. Both outputs are disabled and the regulator draws only 70µA of quiescent current.

The regulator is protected against overvoltage conditions. Both out- puts are protected against short circuit and thermal runaway conditions.

The CS8147 is packaged in a 5 lead TO-220 with copper tab. The cop- per tab can be connected to a heat sink if necessary.
