1 General Description The LSP78XX are 3 terminal bipolar linear regulators. They can deliver over 1A output current if the operation heat well dissipated through the heat sink. These regulators are available in TO220-3L and TO252-2L packages. The fixed output voltage of the LSP78XX are set at the factory and trimmed to meet ±2% (25 o C) tolerance. This family of regulators can provide either a stand-alone power supply solution or act as a post regulator for switch mode power supplies. Features Maximum Output Current of 1A Output Voltage Available in 5V, 6V, 8V, 9V, 12V, 15V, 18V Over Temperature Shutdown Short Circuit Protection ±2% VOUT Tolerance (25 o C). ±4% VOUT Tolerance (-40 ~125 o C). Package: TO220-3L and TO252-2L Applications LCD TV/ Monitors Networking Applications Communication Devices. PC Applications Post Regulator for SMPS Please be aware that an Important Notice concerning availability, disclaimers, and use in critical applications of LSC products is at the end of this document. 1 of 12

Maximum Junction Temperature is the temperature limit of this device. Over this limit, the IC may be damaged permanently. Operation Junction Temperature Range is the range the device intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, please refer to the Electrical Characteristics. Note 2. θ JA is highly dependent on the PCB layout and area. 5 of 12

The maximum steady state usable output current and input voltage are very dependent on the heat sinking and/or lead length of the package. The data above represent pulse test conditions with junction temperature as indicated at the initiation of tests. Note 5. Load and line regulation are specified at constant junction temperature. Changes in V OUT due to heating effects must be taken into account separately. Pulse testing with low duty is used. Note 6. Since products are not screened at high and low temperature, the specification for this temperature range is guaranteed by design, not tested in production. 7 of 12

Alternatively, if the known activation energy for moisture diffusion of the package materials is in the range of ev or ev, the accelerated equivalent may be used. Accelerated soak times may vary due to material properties (e.g.mold compound, encapsulant, etc.). JEDEC document JESD22-A120 provides a method for determining the diffusion coefficient. Note 2: The standard soak time includes a default value of 24 hours for semiconductor manufacturer s exposure time (MET) between bake and bag and includes the maximum time allowed out of the bag at the distributor s facility. If the actual MET is less than 24 hours the soak time may be reduced. For soak conditions of 30 C/60%, the soak time is reduced by 1 hour for each hour the MET is less than 24 hours. For soak conditions of 60 C/60%, the soak time is reduced by 1 hour for each 5 hours the MET is less than 24 hours. If the actual MET is greater than 24 hours the soak time must be increased. If soak conditions are 30 C/60%, the soak time is increased 1 hour for each hour that the actual MET exceeds 24 hours. If soak conditions are 60 C/60%, the soak time is increased 1 hour for each 5 hours that the actual MET exceeds 24 hours.
