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.

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.
