Description

The 52149, which is a replacement for the 79HG, is an adjustable 4-terminal voltage regulator capable of supplying in excess of 5 A over a 24 V to -2.55 V output range. This Hybrid Voltage Regulator has been designed with all the inherent characteristics of the monolithic 4-terminal regulator; i.e., full thermal overload and short circuit protection.  It is packaged in a hermetically sealed 4-pin, TO-3 package providing 50W power dissipation.  The regulator 52149 consists of a monolithic chip driving a discrete series-pass element and short circuit detection transistors.
