TS78L00 series 3-Terminal Low Current Positive Voltage Regulator Voltage Range 5V to 24V Output Current up to 100mA General Description The TS78L00 Series of positive 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 TS7800 and TS78M00 Series cousins, these regulators feature internal current limiting and thermal shutdown making them remarkably rugged. No external components are required with the TS78L00 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 Standard Application 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 Ordering Information A common ground is required between the input and the output voltages. The input voltage must remain typically Part No. Operating Temp. Package 2.0V above the output voltage even during the low point (Ambient) on the Input ripple voltage.
