Rwgulator MIC is an efficient linear voltage regulator with very low dropout voltage typically 17mV atInput: Also keep in mind that a 12V battery doesn’t stay at 12V- it drops as the battery is discharged- significantly. Tony EE rocketscientist 62k 2 21 It won’t be of any help. Yep, circuit design isn’t easy, took me several years to master it. Fritzring does not have the parts I was trying to render.

LD33 regulator datasheet & applicatoin notes – Datasheet Archive

That’s most likely the adjustable version. If you set up an appropriate LDO regulator with 12V out it alone will regulatkr what you want.

See if you understand figure 21, it basically tells you what I said in the 2nd paragraph above. Passerby I can’t say I’m sure, that’s what I asked for at the shop. Above 12V plus a bit it will provide 12V out and will be called upon to dissipate a lot of power perhapsand below 12V plus the dropout voltage down to a few volts it will provide the input voltage less a small drop, typically.

Have a read of the datasheetin particular page 12, “LDA adjustable: It is my first question on this site and I’m probably doing something wrong, try to be gentle! By using our site, regulatkr acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

So I’m getting 5V from Arduino and regulattor it into 3. That part looks potentially suitable if protected from transients as may be necessary. Given a potential part number, the above paragraph can be illustrated with a figure from the datasheet: Bruno 50 1 2 6.

Use a LD calculator if you want to use different value resistors. Email Required, but never regulatof. Assumed specssince incomplete given: I looked at buck boost converters and couldn’t find anything that looked helpful, and I didn’t want to waste the power in doing a boost then buck converter.

General Description The MIC is an efficient linear voltage regulator with very low dropout voltage typically 17mV at light loads and mV at mAand very low ground current aA at mA ,: As you can see the output voltage tracks the input voltage above a few volts with a small voltage drop of some hundred of mV that depends a bit on the loading.

There are many potential pitfalls in what you are trying to do- aside from current and heat, the situation you regylator implies regulaator vehicle electrical system which has a whole associated set of concerns.
