  • 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. 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.

Features

  • 3-Terminal Regulators
  • Available in fixed 5-V/8-V/10-V/12-V/
    15-V/24-V options
  • Output Current up to 1.5 A
  • Internal Thermal-Overload Protection
  • High Power-Dissipation Capability
  • Internal Short-Circuit Current Limiting
  • Output Transistor Safe-Area Compensation
  • Output Capacitor Not Needed for Stability
