All rights reserved. These regulators can provide local on-card regulation, eliminating the distribution problem associated with single point regulation.
Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current, although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.
