TX78XX is three-terminal positive regulators. One of these regulators can deliver up to 1A of output cu r rent.
    The inte rnal limiting and therm al-shutdown features of the regulator make them essentially immune to overload.
    When used as a replacement for a zener diode-resistor Combination, an effective improvement in output impedance can be obtained, together with lower quiescent current.

Output Current of 1A

Thermal Overload Protection

Short Circuit Protection

Output transistor safe area protection

No external components
