description
This series of fixed negative-voltage integrated-circuit
voltage regulators is designed for a wide range of
applications. These include on-card regulation for

elimination of noise and distribution problems
associatedwith single-point regulation. In addition,
they can be used to control series pass elements to make high-current voltage-regulator circuits. One of these
regulators can deliver up to 100 mA of output current. The internal current-limiting and thermal-shutdown features
make them essentially immune to overload. When used as a replacement for a zener-diode and resistor combination,
these devices can provide effective improvement in output iimpedance of two orders of magnitude, with lower bias
current.

‡ Pulse-testing techniques maintain TJ as close to TA as possible. Thermal effects must be taken into account separately. All characteristics are
measured with a 0.33-µF capacitor across the input and a 0.1-µF capacitor across the output. Full range for the 79L08 is T J = 0°C to 70°C
