Features
Description
• Wide selection of available fixed output voltages
• Available in space saving SOT-89 package
• Low cost
The MC78L00 series of positive voltage regulators are
designed to provide a range of regulated power supply
voltages for low current applications of up to 100mA.
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 MC78M00 and MC7800 family..
• Internal short circuit current limiting
• Internal thermal overload protection
• No external components required
• Complementary negative voltage regulators also available
(MC79L00)
No external components are required with the MC78L00
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.
