| Solved by SP317 TM 3-Terminal 1 Amp Adjustable Voltage Regulator Features Typical 1% Output Voltage Tolerance Typical 0.01%/V Line Regulation Typical 0.2% Load Regulation Very Low Dropout Voltage: 1.2V at 1A Output Current Trimmed Current Limit On-chip Thermal Protection Operation Junction Temperature: 0 to 125oC Available in RoHS Compliant, Lead Free Packaging TO-220 Package 3 VOUT 2 1 INPUT OUTPUT ADJ Applications PC Motherboard LCD Monitor Graphics Card DVD Player Network Interface Card/Switch Telecom Equipment Printer and other Peripheral Equipment general Description The SP317 is an adjustable three-terminal positive voltage regulator with a very low dropout of 1.2V at 1A output current. Using 2 external resistors, the SP317 can provide an adjustable output voltage down to 1.25V. The SP317 includes a circuit of trimmed bandgap reference to assure output voltage accuracy to be within 1%. It also provides current limiting and thermal shutdown. The current limit is trimmed to ensure specified output current and controlled short-circuit current. The On-chip thermal limiting provides protection against any combination of overload and ambient temperature that would create excessive junction temperature. The SP317 is available in the standard SOT-223, TO-220, TO-252 and TO-263 power packages. SOT-223 TO-220 TO-22 TO-263 Figure .

Typical Application of SP 3 7 * = CIN is required if the regulator is located near power supply filter. **= CO is needed for stability and it improves transient response. VOUT = VREF x (+R2/R) + IADJ x R2 Since IADJ is controlled to less than 00 A, the error associated with this term is negligible in most applications.
