[SOLVED] 5v/2.5A regulated power supply with a single IC

[rafeeqmpm]

Hi,
In my circuits I am using LM 7805 as regulator IC. But the problem rises whenever my circuits will take more current. Will you please suggest any single IC that can provide up to 2.5A/5v regulated power supply?

Hi,

Why don't you go to a distributor or a voltage regulator manufacturer internet site and use the parametric search?
At least this is what I'd do.

But using linear regulators for high current usually means high power dissipation (heat), thus there are switch mode replacements.
Just do a search.

Hi,

I don't know which housing you are prefere but a suitable TO-220 regulator would be the LM1084IT-5.0 [1]. Keep in mind the dropout voltage at 2.5 A is in the range of 1.1 A, which leads to a minimum power dissipation of 2.75 W. Depending on your input voltage (and chosen package) the temperature and losses are quite high. To keep the losses and temperature low, a switched regulator will be more favourable as @KlausST suggested.
