I want to use a cheap 3.3V regulator in my project that uses an LIR2450 3.6V lithium ion coin cell battery. I noticed there are many buck/boost +3.3V switching regulators specifically for lithium ion batteries. I would prefer using an LDO linear 3.3V regulator for the lower cost and not having to use many external components. Is there a problem with using this type of regulator with a lithium ion battery? There might be another issue in the dropout voltage being too high. I'm not sure how long it would take for the LIR2450 to get below 3.6V (I found a regulator with a 0.3V dropout). Just wondering if you can give advice about this before I order parts and do testing...thanks!
