3-Terminal Regulators
Output Current Up to 1.5 A
No External Components
Internal Thermal Overload Protection
High Power Dissipation Protection
Internal Short-Circuit Current Limiting
Output Transistor Safe-Area Compensation
DESCRIPTION
www.DataSheet4UT.chomis series of fixed-voltage monolithic integrated-circuit voltage
regulators designed for a wide range of applications. These
applications include on-card regulation for elimination of noise and
distribution problems associated with single-point regulation. Each of
these regulators can deliver up to 1.5 amperes of output current. The
internal limiting and termal shutdown features of these regulators
make them essentially immune to overload.

*Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as
possible. Thermal effects must be taken into account separately.
** This specification applies only for dc power dissipation permitted by absolute maximum ratings.
