TS78M00 Series 3-Terminal 500mA Positive Voltage Regulator TO-252 Pin Definition: (DPAK) 1. Input 2. Ground (tab) 3. Output General Description The TS78M00 Series positive voltage regulators are identical to the popular TS7800 Series devices, except that they are specified for only half the output current. Like the TS7800 devices, the TS78M00 Series 3-Terminal regulators are intended for local, on-card voltage regulation. Internal current limiting, thermal shutdown circuitry and safe-area compensation for the internal pass transistor combine to make these devices remarkably rugged under most operating conditions. Maximum output current with adequate heatsink is 500mA Features Standard Application Circuit Output Voltage Range 5 to 24V Output current up to 500mA No external components required Internal thermal overload protection Internal short-circuit current limiting Output transistor safe-area compensation Output voltage offered in 4% tolerance Ordering Information A common ground is required between the input and the Part No. Package Packing output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low point TS78MxxCP ROG TO-252 2.5Kpcs / 13 Reel on the Input ripple voltage. Note: G denotes for Halogen Free XX = these two digits of the type number indicate voltage. Note: Where xx denote voltage option, available are: * = Cin is required if regulator is located an appreciable 05=5V, 08=9V, 09=9V, 12=12V, 15=15V, distance from power supply filter. ** = Co is not needed for stability however, it does 18=18V, 24=24V improve transient response.
