CS8361
5.0 V Dual Micropower
Low Dropout Regulator
with ENABLE and RESET
The CS8361 is a precision Micropower dual voltage regulator with
ENABLE and RESET.
http://onsemi.com
The 5.0 V standby output is accurate within 2% while supplying
loads of 100 mA and has a typical dropout voltage of 400 mV.
Quiescent current is low, typically 140 mA with a 300 mA load. The
active RESET output monitors the 5.0 V standby output and is low
during power−up and regulator dropout conditions. The RESET
circuit includes hysteresis and is guaranteed to operate correctly with
1.0 V on the standby output.
The second output tracks the 5.0 V standby output through an
external adjust lead, and can supply loads of 250 mA with a typical
dropout voltage of 400 mV. The logic level ENABLE lead is used to
control this tracking regulator output.
Both outputs are protected against overvoltage, short circuit, reverse
battery and overtemperature conditions. The robustness and low
quiescent current of the CS8361 makes it not only well suited for
automotive microprocessor applications, but for any battery powered
microprocessor applications.

tracking regulator of the standby output. By using the
standby output as a voltage reference, giving the user an
external programming lead (Adj lead), output voltages from

OUT1(max)
Output capacitors for the CS8361 are required for
stability. Without them, the regulator outputs will oscillate.
Actual size and type may vary depending upon the
application load and temperature range. Capacitor effective
series resistance (ESR) is also a factor in the IC stability.
Worst−case is determined at the minimum ambient
temperature and maximum load expected.
Output capacitors can be increased in size to any desired
value above the minimum. One possible purpose of this
would be to maintain the output voltages during brief
conditions of negative input transients that might be
characteristic of a particular system.
Capacitors must also be rated at all ambient temperatures
expected in the system. To maintain regulator stability down
to −40°C, capacitors rated at that temperature must be used.
