    General Description
    TX78XX is threeterminal positive regulators One
    of these regulators can deliver up to 15A of
    output current The internal limiting and thermal
    shutdown features of the regulator make them
    essentially immune to overload When used as a
    replacement for a zener dioderesistor
    Combination an effective improvement in output
    impedance can be obtained together with lower
    quiescent current

    Operation Description
    HE78XX is designed with Thermal Overload Protection that shuts down the circuit when subjected to
    an excessive power overload condition Internal Short Circuit Protection that limits the maximum current
    the circuit will pass and Output Transistor SafeArea Compensation that reduces the output short
    circuit current as the voltage across the pass transistor is increased
    In many low current applications compensation capacitors are not required However it is recommended
    that the regulator input be bypassed with a capacitor if the regulator is connected to the power supply
    filter with long wire lengths or if the output load capacitance is large An input bypass capacitor should be
    selected to provide good high frequency characteristics to insure stable operation under all load
    conditions A 033μFor larger tantalum mylar or other capacitor having low internal impedance at high
    frequencies should be chosen The bypass capacitor should be mounted with the shortest possible leads
    directly across the regulator’s input terminals Normally good construction techniques should be used to
    minimize ground loops and lead resistance drops since the regulator has no external sense lead
    Typical Application
    HE78XX
    A common ground is required between the input and the output voltages The input voltage must remain
    typically 20 V above the output voltage even during the low point on the input ripple voltage
    ●Cin is required if regulator is located an appreciable distance from power supply filter
    ●Co is not needed for stability however it does improve transient response
    HE78XX
    The HE78XX regulator can also be used as a current source when connected as Fig2 In order to
    minimize dissipation the HE78XX is chosen in this application Resistor R determines the current
    as
