TS78M05A 3-Terminal 500mA Positive Voltage Regulator TO-252 (DPAK) Pin Definition: 1. Input 2. Ground (tab) 3. Output General Description The TS78M05A Series positive voltage regulators are identical to the popular TS7805 Series devices, except that they are specified for only half the output current. Like the TS7805 devices, the TS78M05A 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 5V Output current up to 500mA Internal thermal overload protection Internal short-circuit current limiting Output transistor safe-area compensation Output voltage offered in 2% tolerance Ordering Information Part No. Package Packing TS78M05ACP RO TO-252 2.5Kpcs / 13" Reel A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low point on the Input ripple voltage. XX = these two digits of the type number indicate voltage. * = Cin is required if regulator is located an appreciable distance from power supply filter. ** = Co is not needed for stability; however, it does improve transient response.
