CS8161

CS8161 CS8161 12V, 5V Low Dropout Dual Regulator with ENABLE Description The CS8161 is a 12V/5V dual output linear regulator. The 12V ± 5% output sources 400mA and the 5V ±2.0% output sources 200mA. The on board ENABLE function controls the regulatorÕs 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 can be connected to a heat sink if necessary. It is also available in a 16 lead SO wide package.
