TS79L00 series

3-Terminal Low Current Negative Voltage Regulator

Voltage Range - 5V to - 24V Output Current up to 100m A

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 100m A. 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 Standard Application Output current up to 100m A No external components required Internal thermal overload protection Internal short-circuit current limiting Output transistor safe-area compensation Output voltage offered in 4% tolerance
