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

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.

Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as
possible, and thermal effects must be taken into account separately.
