Description
The R1122N401A-TR is a CMOS-based LDO regulator in the R1112N/R1122N Series. It is designed with a 150mA output, high ripple rejection, and excellent load transient response. This makes it an ideal choice for power source applications in hand-held communication equipment. The regulator offers selectable polarity of the CE pin and comes in two different pin layouts: R1112N and R1122N. It is compatible with ceramic capacitors.
