Features
Description
The L78xxAB L78xxAC series of three terminal
positive regulators are available in TO-220,
TO-220FP, and D
fixed output voltages, making it useful in a wide
range of applications. 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.
Table 1.
Output current in excess of 1 A
Output voltages of 5; 6; 8; 9; 12; 15; 24 V
Thermal overload protection
Output transition SOA protection
2 % Output voltage tolerance
Guaranteed in extended temperature range
