Frequently Asked Questions
What kind of capacitor must I use with this regulator?
You can use a ceramic capacitor that is 1μF or more.
How do I select the specific output voltage for the device?
The desired VOUT (between 0.8V and 3.6V) is specified by selecting the .xx. code in 0.1V steps.
What is the typical dropout voltage (VDIF)?
The typical Dropout Voltage (VDIF) is 0.25V, based on IOUT=300mA and VOUT=2.8V.
Does this product comply with environmental standards?
Yes, according to the guidelines, products shipped after April 1, 2006, comply with the RoHS Directive because they are lead-free.
