TS79M00 Series 3-Terminal 500mA Negative Voltage Regulator TO-220 TO-252 Pin Definition: (DPAK) 1. Ground 2. Input (tab) 3. Output General Description The TS79M00 series of fixed output negative voltage regulators are intended as complements to the popular TS78M00 series device. These negative regulators are available in the same seven-voltage options as the TS7900 devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative TS79M00 Series. Available in fixed output voltage options from -5.0 to -24 volts, these regulators employ current limiting, thermal shutdown, and safe-area compensation--making them remarkably rugged under most operating conditions. With adequate heat sinking they can deliver output currents in excess of 0.5 ampere. Features Standard Application Circuit Output Voltage: -5 & -12V 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 Part No. Package Packing the Input ripple voltage.
