APE8843
DESCRIPTION
The APE8843 is an efficient, precise dual-channel CMOS
LDO regulator optimized for ultra-low-quiescent applications.
Regulators output1 and output2 are capable of sourcing
600mA of output current. The regulators are stable with output
capacitors as low as 1uF, including current limit, thermal
shutdown protection, fast transient response, low dropout
voltage, high output accuracy, current limiting protection, and
high ripple rejection ratio. The APE8843 regulators are able to
support individual On/Off function. The APE8843 regulators are
available in used ESOP-8 package.

-V
OUT
, which is measured when V

drop about 100mV.
Note 2：Regulation is measured at a constant junction temperature by using 30ms current pulse and load regulation in the load range from
0mA to 600mA.
