Description
The L79 series of three-terminal negative
regulators is available in TO-220, TO-220FP and
D²PAK packages and several fixed output
voltages, making it useful in a wide range of
applications.
These regulators can provide local on-card
regulation, eliminating the distribution problems
associated with single point regulation;
furthermore, having the same voltage option as
the L78 positive standard series, they are
particularly suited for split power supplies. If
adequate heat sinking is provided, they can
deliver over 1.5 A output current.
Although designed primarily as fixed voltage
regulators, these devices can be used with
external components to obtain adjustable
voltages and currents.

Figure 4: Fixed output regulator
CI is required for stability. For value given, capacitor must be solid tantalum. If
aluminium electrolytic are used, at least ten times value should be selected. CO is
required if regulator is located an appreciable distance from power supply filter. To
improve transient response. If large capacitors are used, a high current diode from
input to output (1N4001 or similar) should be introduced to protect the device from
momentary input short circuit.
