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.

Standard Application

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.
