R1114x/R1124N Series  
150mA LDO  
The R1114x/R1124N Series are CMOS-based LDO regulators featuring 150mA output. High ripple rejection and excellent load  
transient response of the series make the product ideally suited for use in power source for hand-held communication equipment.  
The polarity of the CE pin can be selected. The auto-discharge function is also available (see Selection Guide). Two different pin  
layout as R1114N and R1124N are available. Ceramic capacitors can be used.
