Dobry den,<br>riesim nasledujucu vec. Potrebujem napajat chip od STmicroelectronics STE100P(datasheet - <a href="http://www.st.com/stonline/products/literature/ds/6806.pdf">http://www.st.com/stonline/products/literature/ds/6806.pdf
</a> ) napatim 3,3V. Kedze vysledne zariadenie bude prenosne, potrebujem zabezpecit aby toto napatie pochadzalo z napr. AAA tuzkovych baterii. <br>V tzv. application note ( <a href="http://www.st.com/stonline/products/literature/an/7353.pdf">
http://www.st.com/stonline/products/literature/an/7353.pdf</a> ) k chipu STE100P je napr pouzity low drop regulator od STcka LE33C ( <a href="http://www.st.com/stonline/products/literature/ds/2573.pdf">http://www.st.com/stonline/products/literature/ds/2573.pdf
</a> ), ktory by mal byt k dostaniu v ERA components( <a href="http://www.eracomponents.cz">http://www.eracomponents.cz</a> ).<br>No a teraz prichadza moja otazka. Napajanie tohto regulatoru je v katalogovom liste uvedene ako max. 18V, ale minimalna hodnota uvedena nieje. Je teda jedno kolko tuzkovych baterii pouzijem? Aky je podla Vas optimalny pocet baterii a ako to zapojit k tomu regulatoru aby to fungovalo korektne. Privital by som aj konkretne schema.
<br><span>Nebranim sa pouzitiu ani inych okamzite dostupnych regulatorov.<br><br>Uvitam vsetky podnety, napady a dobre rady.<br>Dakujem.<br><br>Tomas Lehotsky </span><br><br><br>
