CS-5201 1Amp Low Dropout Positive Voltage Regulator
Pin Functions (5-Lead)
Sense (Pin 1): This pin is the positive side of the
reference voltage. With this pin it is possible to Kelvin
Sense the output voltage at the load.0000000000000000
Adjust (Pin 2): This pin is the negative side of the
reference voltage. Adding a small bypass capacitor from
the Adjust pin to ground improves the transient response.
For fixed voltage devices the Adjust pin is also brought
out to allow the user to add a bypass capacitor.00000000
GND (Pin 2): For fixed voltage device this is the bottom
of the resistor divider that sets the output voltage.000000
V_POWER (Pin 5): This pin is the collector of the power
transistor. The output load current is supplied through this
pin. The voltage at this pin must be 0.7V greater than the
output voltage for the device to regulate.0000000000000000
V_CONTROL (Pin 4): This pin is the supply pin for the control
circuitry. The current flow into this pin will be about 1% of
the output current. The voltage at this pin must be 1.3V
greater than the output voltage for the device to regulate.
Output (Pin 3): This is the power output of the device.000
