Description
The R1112N/R1122N Series are CMOS-based LDO regulators featuring 150mA output. High ripple rejection and excellent load transient response make the product ideally suited for use in power sources for handheld communication equipment. The polarity of the CE pin can be selected, and two different pin layouts are available. Ceramic capacitors can be used.
