  • TLV760  -  TLV760 is a wide input (30V) Low current (100mA) linear regulator

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.

Features

  • 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
  • APPLICATIONS
    • On-Card Regulation
    • Portable Devices
    • Computing & Servers
    • Telecommunications
