DESCRIPTION
The 52149/52174, 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 consists of a monolithic chip
driving a discrete series-pass element and short circuit detection transistors.
