HSMC Product Specification
Description
The H78XX series can provide local on-card regulation, eliminating the
distribution problems associated with single point regulation. Each
employs internal current limiting, thermal shut-down and safe operating
area protection, making it essentially indestructible. If adequate heat
sinking is provided, they can deliver over 1A output current. Although
designed primarily as fixed voltage regulators, these devices can be used
with external components to obtain adjustable voltages and currents.
