TS78M00 series 3-Terminal Medium Current Positive Voltage Regulator Pin assignment: Voltage Range 5V to 24V 1. Input Output Current up to 0.5A 2. Ground 3. Output (Heatsink surface connected to Pin 2) 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 This series is offered in 3-pin TO-220, TO-252 package. Features Standard Application Output current up to 0.5A No external components required Internal thermal overload protection Internal short-circuit current limiting Output transistor safe-area compensation Output voltage offered in 4% tolerance A common ground is required between the input and the Ordering Information output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low point on the Part No. Operating Temp. Package Input ripple voltage.
