CS8147
10 V/5.0 V Low Dropout
Dual Regulator with ENABLE
The CS8147 is a 10 V/5.0 V dual output linear regulator. The 10V
±5.0% output sources 500 mA and the 5.0 V ±3% output sources 70
mA. The secondary output is inherently stable and does not require an
external capacitor.
The on board ENABLE function controls the regulator’s two
outputs. When ENABLE
is high, the regulator is placed in SLEEP
mode. Both outputs are disabled and the regulator draws only 70 µA of
quiescent current.
The regulator is protected against overvoltage conditions. Both
outputs are protected against short circuit and thermal runaway
conditions.
The CS8147 is packaged in a 5 lead TO–220 with copper tab. The
copper tab can be connected to a heat sink if necessary.
Features
