TS79L00

TS79L00 series 3-Terminal Low Current Negative Voltage Regulator Voltage Range - 5V to - 24V Output Current up to 100mA 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. This series is offered in 3-pin TO-92, SOT-89 and 8-pin SOP-8 package. Features Output current up to 100mA No external components required Internal thermal overload protection Internal short-circuit current limiting Output transistor safe-area compensation Output voltage offered in 4% tolerance Standard Application Ordering Information Part No. TS79LxxCT TS79LxxCY TS79LxxCS Note: Where xx denotes voltage option. -20 ~ +85 C o Operating Temp. (Ambient) Package TO-92 SOT-89 SOP-8 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.
