Features

Description

• Wide selection of available fixed output voltages

• Low cost

The MC79L00 series of negative voltage regulators are

designed to provide a range of regulated power supply

voltages for low current applications of up to 100mA.

• Internal short circuit current limiting

• Internal thermal overload protection

• No external components required

They are low cost, rugged, easy to use, three terminal

devices with internal current limiting and thermal shut-

down protection and are the low current members of the

popular MC79M00 and MC7900 family.

• Complementary positive voltage regulators also available

(MC78L00)

No external components are required with the MC79L00

in most applications.

• Accurate, ± 2% output voltage tolerance

These products offer an improved replacement for the

traditional zener-resistor combination, providing better

output impedance, lower internal power dissipation and

lower quiescent current.

• To maintain the specified junction temperature, low duty cycle pulse testing is required for most parameters. All characteristics are measured with a 0.33µF

capacitor across the input and a 0.1µF capacitor across the output.
