The AP22800 is designed to operate from 1.5V to 5.5V making it ideal
for 1.8V, 2.5V, 3.3V, 5V voltage rails. The low quiescent supply
current specification of 21µA makes it ideal for use in battery powered
distribution systems where power consumption is a concern.
U-DFN2116-8
The AP22800 is available in a standard Green U-DFN2116-8
package with an exposed PAD for improved thermal performance and
is RoHS compliant.
