L78S
2 A positive voltage regulator IC
Datasheet - production data
Description
TO-220
Features
• Output current up to 2 A
• Output voltages of 5; 7.5; 9; 10; 12; 15; 18; 24 V
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.
• Thermal protection
• Short circuit protection
• Output transition SOA protection
