Product Description

0.6uA "No CL Cap" Ultra Low Quiescent Current LDO

Not only does the XC6504 have the lowest quiescent current figure of any of our LDOs, it also has the added benefit of providing stable output voltages within a range of 1.1V ~ 5.0V (100mV steps) even without a load capacitor (CL)!

This is possible because phase compensation is carried out internally unlike other LDOs where it is done externally.

The operating voltage range is from 1.4V ~ 6.0V and the LDO can also be switched off via the CE pin thereby reducing current consumption even further in stand-by to just 0.01μA.

The XC6504 also features a current limiter, short circuit protection and an automatic CL discharge function (should you choose to use a CL capacitor).

Available in SOT-25, SSOT-24, USPQ-4B04 and a tiny USPN-4B02 package measuring just 0.75mm x 0.95mm x 0.4mm!
