MC33761 - ON Semiconductor

MC33761 Ultra Low-Noise Low Dropout Voltage Regulator

Pin # Pin Name Function 1 Vin Powers the IC 2 GND The IC’s ground 3 ON/OFF Shuts or wakes−up the IC 4 NC None 5 Vout Delivers the output voltage Description A positive voltage up to 12 V can be applied upon this pin. A 900 mV level on this pin is sufficient to start the IC. A 150 mV shuts it down. It makes no arm to connect the pin to a kn.
