The CS8156 is a low dropout 12 V/5.0 V dual output linear regulator.The 12 V ±5.0% output sources 750 mA and the 5.0 V ±2.0% output sources 100 mA.
The on board ENABLE function controls the regulator's two outputs. When the ENABLE lead is low, the regulator is placed in SLEEP mode. Both outputs are disabled and the regulator draws only 200 nA of quiescent current.
The regulator is protected against overvoltage conditions. Both outputs are protected against short circuit and thermal runaway conditions.
The CS8156 is packaged in a 5 lead TO220 with copper tab. The copper tab can be connected to a heat sink if necessary.
