µA78Mxx Positive-Voltage Regulators
1 Features
1 3-Terminal Regulators
• Output Current up to 500 mA
• No External Components
• Internal Thermal-Overload Protection
• High Power-Dissipation Capability
• Internal Short-Circuit Current Limiting
• Output Transistor Safe-Area Compensation
2 Applications
• On-Card Regulation
• Portable Devices
• Computing & Servers
• Telecommunications
3 Description
This series of fixed-voltage integrated-circuit voltage
regulators is designed for a wide range of
applications. The 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 500 mA 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 as the power-pass element in precision
regulators.
