SLVS058F - JUNE 1976 - REVISED FEBRUARY 2005 KCS (TO-220) PACKAGE (TOP VIEW) 3-Terminal Regulators Output Current Up To 1.5 A No External Components Internal Thermal Overload Protection High-Power Dissipation Capability Internal Short-Circuit Current Limiting Output Transistor Safe-Area Compensation INPUT D D D D D D D OUTPUT INPUT COMMON KTE PACKAGE (TOP VIEW) description/ordering information INPUT OUTPUT This series of fixed-negative-voltage INPUT integrated-circuit voltage regulators is designed COMMON to complement Series A7800 in 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 A of output current. The internal current limiting and thermal shutdown features of these regulators essentially make them immune to overload. In addition to use as fixed-voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents and also as the power-pass element in precision regulators.

None: Not yet available Lead (Pb-Free). Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens, including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
