2 / 10 page NCP3985 http://onsemi.com 2 Figure 2. Simplified Block Diagram Current Limit Bandgap Reference Voltage CE GND Active Discharge Vout Vin Cnoise PIN FUNCTION DESCRIPTION Pin No. Pin Name Description 1 Vin Power Supply Input Voltage 2 GND Power Supply Ground 3 CE Chip Enable: This pin allows on/off control of the regulator. To disable the device, connect to GND. If this function is not in use, connect to Vin. Internal 5 MW Pull Down resistor is connected between CE and GND. 4 Cnoise Noise reduction pin. (Connect 100 nF or 10 nF capacitor to GND) 5 Vout Regulated Output Voltage MAXIMUM RATINGS Rating Symbol Value Unit Input Voltage (Note 1) Vin -0.3 V to 6 V V Chip Enable Voltage VCE -0.3 V to Vin +0.3 V V Noise Reduction Voltage VCnoise -0.3 V to Vin +0.3 V V Output Voltage Vout -0.3 V to Vin +0.3 V V Maximum Junction Temperature (Note 1) TJ(max) 150 °C Storage Temperature Range TSTG -55 to 150 °C Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. NOTE: This device series contains ESD protection and exceeds the following tests: Human Body Model 2000 V per MIL-STD-883, Method 3015 Machine Model Method 200 V THERMAL CHARACTERISTICS Rating Symbol Value Unit Package Thermal Resistance: (Note 1) Junction-to-Lead (pin 5) Junction-to-Ambient RθJA 109 220 °C/W 1.
