NCV8570B Linear Voltage Regulator - LDO, Ultra Low Noise, High PSRR 200 mA NCV8570B R DIS R PD Figure 2. Simplified Block Diagram PIN FUNCTION DESCRIPTION Pin No. Pin No. DFN6 TSOP5 Pin Name Description 1 3 EN Enable pin: 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 M Pull Down resistor is connected between EN and GND. 2, 5, EPAD 2 GND Power Supply Ground (Pins are fused for the DFN6 package). Pins 2, 5 and EPAD are connected together through the lead frame in the DFN6 package. 3 1 IN Power Supply Input Voltage 4 5 OUT Regulated Output Voltage 6 4 BYP Noise reduction pin.
