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

elementstomakehigh-currentvoltageregulators.

One of these regulators can deliver up to 100 mA

of output current. The internal limiting and

thermal-shutdown features of these regulators

makethemessentiallyimmunetooverload. 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 T as close to T 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 = 0°C to 70°C
