description
This series of fixed-voltage integrated-circuit
voltage regulators is designed for a wide range of
applications. These applications include on-card
regulation for elimination of noise and distribution
problems associated with single-point regulation.
In addition, they can be used with power-pass
elements to make high-current voltage regulators.
One of these regulators can deliver up to 100 mA
of output current. The internal limiting and
thermal-shutdown features of these regulators
make them essentially immune to overload. When
used as a replacement for a zener diode-resistor
combination, an effective improvement in output
impedance can be obtained, together 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 78L05 is T J = 0°C to 70°C
