Output current 1.5A 3-Terminal Regulators Internal Thermal Overload Protection Internal Short-Circuit Current Limiting Output Transistor Safe-Area Protection Wide Range of Output Voltages TO-220, TO-252 and TO-263 Packages High Power Dissipation Capability Direct replacements for LM78xx The GM7800 series are classic regulators useful in a wide range of applications. For example, you can use them for local on-card regulation to eliminate the distribution problems associated with single point regulation. The wide range of output voltages to 27V) make them useful in an endless list of applications. Although designed as fixed voltage regulators, you can add a few external components to make adjustable voltages and currents. Current limiting prevents the peak output current to a safe value. Safe-area protection for the output transistor limits internal power dissipation. If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown circuit activates to prevent the regulator from overheating. These versatile workhorses are easy to use. You do not need to bypass the output, although this does improve transient response. Input bypassing is needed only if you place the regulator far from the filter capacitor of the power supply. The GM7800 series is available TO-220, TO-252 and TO-263 packages.
