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.
∗) R1114N Series are suitable for automotive applications too. Please refer to our "Car Electronics Products Catalog" or contact us.
