52149/52174 79HG REPLACEMENT NEGATIVE ADJUSTABLE 5-AMP VOLTAGE REGULATOR Mii HYBRID MICROELECTRONICS PRODUCTS DIVISION Features: • • • • • • • • Replacement for 79HG 5.0A Output Current Internal Current And Thermal Overload Protection Internal Short Circuit Current Limit Low Drop-Out Voltage (Typically -2.2 V @ 5.0 A) 50W Power Dissipation Electrically Isolated Case Steel TO-3 Case Applications: • • Designed for use in general purpose applications where adjustability is advantageous. Military and Hi Rel Industrial applications where hermeticity is required. ORDER INFORMATION 52149 Standard 52174 MIL-STD-883 Screened 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.
