description

This series of fixed-voltage integrated-circuitvoltage regulators is designed for a wide range ofapplications. These applications include on-cardregulation for elimination of noise and distribution

problems associated with single-point regulation.In addition, they can be used with power-passelements to make high-current voltage regulators.One of these regulators can deliver up to 100 mA

of output current. The internal limiting andthermal-shutdown features of these regulatorsmake them essentially immune to overload. When

used as a replacement for a zener diode-resistorcombination, an effective improvement in outputimpedance can be obtained, together with lowerbias 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-F capacitor across the input and a 0.1-F capacitor across the output. Full range for the 78L05 is T J = 0C to 70C
