The CS8161 is a 12V/5V dual output linear regulator. The 12V ± 5% output provides 400mA and the 5V ±2.0% output provides 200mA. The on-board ENABLE function controls the regulator's two outputs. When the ENABLE pin is low, the regulator is placed in SLEEP mode. Both outputs are disabled and the regulator draws only 200nA of quiescent current. The primary output, VOUT1, is protected against overvoltage conditions. Both outputs are protected against short circuit and thermal runaway conditions. The CS8161 is packaged in a 5 lead TOÐ220 with copper tab. The copper tab serves as the power supply pin.
