AP2111 Datasheet, PDF (1/2 Pages) BCD Semiconductor Manufacturing Limited – 600mA CMOS LDO REGULATOR WITH ENABLE

Product Brief
600mA CMOS LDO REGULATOR WITH ENABLE
AP2111
Description
The AP2111 is CMOS process low dropout linear
regulator with enable function, the regulator
delivers a guaranteed 600mA (min.) continuous
load current
The AP2111 provides 1.2V and 3.3V regulated
output, and provides excellent output accuracy
1.5%, 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.
