[QUOTE="bicter, post: 469580, member: 1240"] hmm the LM317 wont do your job as it has a 3v I/O differential. therefore the absolute maximum regulated O/P would be 5.5V. Have a look at the MIC29302BT available here [url]https://au.rs-online.com/web/p/low-dropout-voltage-regulators/9101395/[/url] It should meet your requirements with a bit further investigation. Data sheet available here [url]https://docs-apac.rs-online.com/webdocs/1385/0900766b813853ad.pdf[/url] Have a good read of the application information starting at page 19 to see if it can be adapted to meet your needs The Dropout Voltage for MIC29300 VOUT = 1% (6) IOUT = 1.5A Typical 250mV (6) Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its normal value with VOUT + 1V applied to VIN. Footnote: I should have asked, are the voltages you require preset or fully adjustable across the range of O/P voltages? If switch selectable voltages are required, then using a pre-selected switched resistor for each voltage may be a better solution than a potentiometer [/QUOTE]
