TS79L00 Series 3-Terminal 100mA Negative Voltage Regulator TO-92 SOT-89 Pin Definition: 1. Ground 2. Input 3. Output General Description The TS79L00 Series of negative voltage regulators are inexpensive, easy-to-use devices suitable for a multitude of applications that require a regulated supply of up to 100mA. Like their higher power TS7900 and TS79M00 Series cousins, these regulators feature internal current limiting and thermal shutdown making them remarkably rugged. No external components are required with the TS79L00 devices in many applications. These devices offer a substantial performance advantage over the traditional zener diode-resistor combination, as output impedance and quiescent current are substantially reduced. Features Standard Application Circuit Output Voltage Range -5V, -9V Output current up to 100mA 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 output voltages. The input voltage must remain typically Part No. Package Packing 2.0V above the output voltage even during the low point on the Input ripple voltage.
