Product overview

Description

The L78S series of three-terminal positive regulators is available in TO-220 package and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 2 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

  • All features

    • Output current up to 2 A
    • Output voltages of 5; 7.5; 9; 10; 12; 15; 18; 24 V
    • Thermal protection
    • Short circuit protection
    • Output transition SOA protection
