DESCRIPTION
The L7900 series of three-terminal negative
regulators is available in TO-220, TO-220FP,
TO-3 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 L7800 positive standard series, they are
particularly suited for split power supplies. In
addition, the -5.2V is also available for ECL
system. If adequate heat sinking is provided, they
can deliver over 1.5A output current.
Although designed primarily as fixed voltage
regulators, these devices can be used with
external components to obtain adjustable voltages
and currents.

APPLICATIONS INFORMATION
Figure 1 : Fixed Output Regulator
NOTE:
1. To specify an output voltage, substitute voltage value for "XX".
2. Required for stability. For value given, capacitor must be solid tantalum. If aluminium electrolytics are used, at least ten times value should
be selected. C1 is required if regulator is located an appreciable distance from power supply filter.
3. 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.
