DESCRIPTION
The LX8585/85A Series ICs are low dropout three-terminal regulators with a minimum of 4.6A output current. Pentium® Processor and Power PCTM applications requiring fast transient response are ideally suited for this product family. The LX8585A is guaranteed to have < 1.2V at 4.6A, while the LX8585 are specified for 1.4V, making them ideal to provide well regulated outputs of 2.5V to 3.6V using a 5V input supply. Fixed versions are also available and specified in the Available Options table below. Current limit is trimmed above 4.6A to ensure adequate output current and controlled short-circuit current. On-chip thermal limiting provides protection against any possible overload that would create excessive junction temperatures. The LX8585/85A family is available in both through-hole and surface-mount versions of the industry standard 3-pin TO-220 / TO-263 power packages.
The LX1431 Programmable Reference and LX8585A Series products offer precision output voltage and are ideal for use in VRE applications (see application below). For higher current applications, see the LX8584 data sheet.

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
