www.DataSheet4U.com Description The GM7800 series are classic regulators, which are useful in a wide range of applications. For example, you can use them for local on-card regulation to eliminate the distribution and problems associated with single point regulation. The wide range of output voltages (5V 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. Curren.

www.DataSheet4U.com Description The GM7800 series are classic regulators, which are useful in a wide range of applications. For example, you can use them for local on-card regulation to eliminate the distribution and problems associated with single point regulation. The wide range of output voltages (5V 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 of 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 bypass is needed only if you place the regulator far from the filter capacitor of the power supply. The GM7800 series is available in TO-220, TO-252 and TO-263 packages. Features Output current up to 1.5A Output Voltages 5V, 6V, 8V, 8.5V, 9V, 10V, 12V, 15V, 18V, 20V, 24V and 27V 3- Terminal Regulators Internal Thermal Overload Protection Internal Short-Circuit Current Limiting Output Transistor Safe-Area Protection TO-220, TO-252 and TO-263 Packages High Power Dissipation Capability Direct replacements for LM78xx Application Post-Regulator Switching DC/DC Converters Bias Supply for Analog Circuits Instrumentation and Audio Systems Logic Systems Others too numerous to mention TYPIC APPLICATION CIRCUITS VIN GM7800 VOUT 1.5A 0.33µF 0.1µF GND For a positive regulator, a 0.33µF bypass capacitor should be used on the input terminals. While not necessary for stability, an output capacitor of 0.1µF may be used to improve the transient response of the regulator. These capacitors should be on or as near as possible to the regulator terminals . www.gammamicro.com GM7800 SERIES V0.1 1 MARKING INFORMATION & PIN CONFIGURATIONS (TOP VIEW) TO-263-2 (D PAK) 2 TO-220 TO-252-3 (DPAK) GM78VV AYWW GM78VV AYWW GM78VV AYWW VV A Y WW =Output Voltage(05: 5.0V, 12: 12V) =Assembly Location =Year =Weekly INPUT GND OUTPUT INPUT GND OUTPUT VIN VOUT TAB is GND ORDERING INFORMATION Pro Number GM7805 GM7806 GM7808 GM7885 GM7809 GM7810 GM7812 GM7815 GM7818 GM7820 GM7824 GM7827 VOUT 5.0V 6.0V 8.0V 8.5V 9.0V 10V 12V 15V 18V 20V 24V 27V Package TO-263, TO-220, TO-252 TO-263, TO-220, TO-252 TO-263, TO-220, TO-252 TO-263, TO-220, TO-252 TO-263, TO-220, TO-252 TO-263, TO-220, TO-252 TO-263, TO-220, TO-252 TO-263, TO-220, TO-252 TO-263, TO-220, TO-252 TO-263, TO-220, TO-252 TO-263, TO-220, TO-252 TO-263, TO-220, TO-252 * For detail Ordering Number identification, please see last page.
