Abstract

The regulator comprises an external JFET transistor (2) which is governed by a control unit (10) to produce a regulated voltage (Vreg1) from a supply (Vhv). The control unit consists of a differential amplifier (4) which is supplied from a voltage divider (5) connected to the regulated voltage and a reference cell (6) and controls the external regulator through a MOSFET transistor (3)
