5v Voltage regulator circuits question

[lloydi12345]

Hi, I would like to power my circuit board. My voltage source is 6v Sealed Lead Acid Battery. There's no problem powering microcontroller and RF Transceiver module but the problem is in powering the camera. The camera needs 5v and 2A to operate. My 7805 can only power it for 1A. Can anyone suggest with what to do with this one? Any answers will be gladly appreciated

How about this:

LM323T
LM323T STMicroelectronics Linear Regulators - Standard

its a 5v@3A Regulator. So it will output as upto 3A of current for you.

Thank you for that AtomSoft, though I have some question. What if I connected the camera here with 2A rating. Will it only get 2A or the whole 3A?

It will take what it needs upto 3A... so if your camera takes like 500mA in standby then it will only draw that much.

3A is the max the circuit can pull.

Woaw just noticed you cant use it tho. It has a input minimum of 7.5v.. ill find you another one

Hi I looked at the stores available in the country but they're not offering this kind of regulator IC. Any more suggestion?

LM2576T-005G looks nice also:
LM2576T-005G ON Semiconductor Switching Converters, Regulators & Controllers
