NCP3011 Product details

Description

Pin Pin Name Description 1 VREF The VREF pin is the output for a 1.25 V reference (1 mA max).A 100 kW resistor in parallel with a 1 mF ceramic capacitor must be connected from this pin to GND to ensure external reference stability.2 EN The EN pin is the enable/disable input.A logic high on this pin enables the device.This pin has also an internal current source pull up.A 10 kW resistor should be connected in series with this pin if VEN is externally biased from a separate supply.3 NC
