RICOH R1114x User Manual

R1114x Series

150mA LDO

The R1114x 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). Ceramic capacitors can be used.
