ZNBG4003
Features
- Four stage FET bias controller Operating range of 5.0V to 8.0V FET drain voltages set at 2.0V FET drain current selectable from 0 to 15m A Allows first and second stage FETs to be run at different (optimum) drain currents FET drain voltages and currents stable over temperature FETs protected against overstress during power-up and power-down. Internal negative supply generator allowing single supply operation (available for external use) Low external ponent count
