R1111N/R1121N Series  
150mA LDO  
<
<
The R1111N/R1121N Series are CMOS-based LDO regulators featuring 150mA output. (Under 1.5V VOUT 1.7V conditions, 100mA)  
=
=
R1111N/R1121N has a high maximum input voltage rating of 8V, which makes the product ideally suitable for use in power source for  
various equipment, including hand-held communication equipment. The polarity of the CE pin can be selected. Two different pin  
layout as R1111N and R1121N are available.
