4 DESCRIPTION
The 78HO5A positive 3 terminal fixed linear voltage regulator is capable of deliver- ing a continous load current in excess of 5 amperes at a nominal regulated output voltage of 5 volts. The 78HO5A has built-in protection features such as output . short circuit current limiting, thermal overload and safe operating area protection. If external conditions exceed the 78H05A’s capabilities (see absolute maximums), : the device temporarily shuts down protecting itself and the load circuit until the fault is removed. This feature eliminates costly additional protection circuitry as well as overly conservative heat sinks typical of discrete high current vollage ~ regulator designs. The 2 lead hermetic T0-204MA (formerly called T0-3) package . provides up to 50 watts of internal power dissipation. 4B FEATURES @5.0A Output Current @ Internal Current and Thermal Overload Protection @ Internal Short Circuit Protection ) @ Low Dropout Voltage (typically 2.3V @ 5.0A) @ 50 W Power Dissipation Forges ype Peokege (Top View) @ Metal 2 lead TO-204MA type package trout AB PRODUCT FAMILY PART NUMBER OUTPUT VOLTAGE DESCRIPTION T8HOSASC 5.0 Volts Commercial Temp 78HOSASM 5.0 Volts Military Temp 78HOSASP 5.0 Volts Military Process
