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.

Definition of Terms
Dropout Voltage: The input-output voltage differential at which
the circuit ceases to regulate against further reduction
in input voltage. Measured when the output voltage
has dropped 100mV from the nominal value obtained
at 14V input, dropout voltage is dependent upon load
current and junction temperature.
Current Limit: Peak current that can be delivered to the output.
Input Voltage: The DC voltage applied to the input terminals
with respect to ground.
Input Output Differential: The voltage difference between the
unregulated input voltage and the regulated output
voltage for which the regulator will operate.
Line Regulation: The change in output voltage for a change in
the input voltage. The measurement is made under
conditions of low dissipation or by using pulse tech-
niques such that the average chip temperature is not
significantly affected.
Load Regulation: The change in output voltage for a change in
load current at constant chip temperature.
Long Term Stability: Output voltage stability under accelerated
life-test conditions after 1000 hours with maximum
rated voltage and junction temperature.
Output Noise Voltage: The rms AC voltage at the output, with
constant load and no input ripple, measured over a
specified frequency range.
Quiescent Current: The part of the positive input current that
does not contribute to the positive load current. The
regulator ground lead current.
Ripple Rejection: The ratio of the peak-to-peak input ripple
voltage to the peak-to-peak output ripple voltage.
Temperature Stability of VOUT: The percentage change in out-
put voltage for a thermal variation from room tempera-
ture to either temperature extreme.
