The R1121 Series are CMOS-based LDO regulators featuring 150mA output. (Under 1.5V ≤ VSET ≤ 1.7V conditions, 100mA)
R1121 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 R1111 and R1121 are available.
