CS8147 Datasheet, PDF (1/8 Pages) Cherry Semiconductor Corporation – 10V/5V Low Dropout Dual Regulator with ENABLE

CS8147
10V/5V Low Dropout Dual Regulator
with ENABLE
Description
Features
The CS8147 is a 10V/5V dual out-
put linear regulator. The 10V ±.5%
output sources 500mA and the 5V
±3% output sources 70mA. The
secondary output is inherently sta-
ble and does not require an external
capacitor.
The on board ENABLE function
controls the regulatorÕs two out-
puts. When ENABLE is high, the
regulator is placed in SLEEP mode.
Both outputs are disabled and the
regulator draws only 70µA of qui-
escent 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.
