regulator with enable function, the regulator delivers
a guaranteed 600mA (Min) continuous load current.
•
•
•
•
•
The AP2111 provides 1.2V, 1.5V, 1.8V, 2.5V, 3.3V,
4.8V regulated output and 0.8V to 5V adjustable
output, and provides excellent output accuracy 1.5%,
it is also provides a excellent load regulation, line
regulation and excellent load transient performance
due to very fast loop response. The AP2111 has
built-in auto discharge function.
•
•
•
•
•
•
•
•
The AP2111 features low power consumption.
The AP2111 is available in SOIC-8, PSOP-8
SOT-223 and SOT-23-5 packages.
