SPX1582 3A Ultra Low Dropout Voltage Regulator
DESCRIPTION
Allows Kelvin sense of V
reference voltage of the device).
Negative side of the reference voltage for the device. Adding a small
bypass capacitor from the ADJ pin to ground will improve the transient
response.
Power output of the device.
Supply pin for the control circuitry of the device. The current flow into this
pin will be about 1% of the output current. V
and 1.3V greater than the output voltage for the device to regulate.
Output load current is supplied through this pin. V
and 0.8V greater than the output voltage for this device to regulate.
