1A Positive Voltage Regulator
Product Description
Features
These voltage regulators are monolithic integrated Output Current in Excess of 1.0 A
circuits designed as Fixed-voltage regulators for a
wide variety of applications including local, on-card
regulation.
No External Components Required
Internal Thermal Overload Protection
Internal Short Circuit Current Limiting
These regulators employ internal current limiting,
thermal shutdown, and safe-area compensation. With
adequate heat sinking they can deliver output
currents in excess of 1.0 A. Although designed
primarily as a fixed voltage regulator, these devices
can be used with external components to obtain
adjustable voltages and currents.
Output Transistor Safe-Area Compensation
Output Voltage Offered in 1% and 2% Tolerance
Available in Surface Mount D2PAK and Standard
3-Lead Transistor Packages
Previous Commercial Temperature Range has
been Extended to a Junction Temperature Range
of 0℃ to +150℃

3Pages Applications Information (Design Considerations)
Globaltech Semiconductor
The GS78xx Series of fixed voltage regulators are 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 Safe-Area
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 0.33 µF or 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 regulators 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.
