Which IC can make 5v power transform to 2.5v?

[ic02]

I need CURRENT 1A.

regulator

Microchip TC57 supplies 2.5, 3.0, 3.3 @4A with an external pnp
transistor.

National Semiconductors

National Semiconductors:

LM2651 (see Datasheet):
1.8V, 2.5V, 3.3V, or ADJ output voltage
4V to 14V input voltage range
High efficiency over a 1.5A to milliamperes load range
Ultra high efficiency up to 97%

This IC costs not very much!

Do you want a switch mode power supply or a linear regulator?

 

[LONG]

there are many Regulator ics to do

AMS1117-2.5,AS1117-2.5!!!!

input 3.3v~5v, output 2.5v derectly!!!

Thank you very much!

It is not easy that AS1117 output 1A current.
