UA7808 描述

This series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. Each of these regulators can deliver up to 1.5 A of output current. The internal current-limiting and thermal-shutdown features of these regulators essentially make them immune to overload. In addition to use as fixed-voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents, and also can be used as the power-pass element in precision regulators.

UA7808 特性

• 3-Terminal Regulators
• Output Current up to 1.5 A
• Internal Thermal-Overload Protection
• High Power-Dissipation Capability
• Internal Short-Circuit Current Limiting
