R1183Z SERIES
150mA LDO REGULATOR
NO.EA-147-070315
OUTLINE
The R1183Z Series are CMOS-based voltage regulator ICs with extremely low supply current, and low
dropout voltage realized with the built-in low ON-resistance Tr.
150mA output current is guaranteed, and the supply current of IC itself is Typ. 1µA at no load.
The R1183Z series have almost same characteristics as R1180x Series. Only difference is ultra small chip
size package (WLCSP4-P2: 0.79mm×0.79mm) and built-in auto discharge function is available with D version,
and output voltage accuracy improved to ±1.2%.
Since the package for these ICs is WLCSP-4-P2, the mount area size is less than 1/4 of R1180D Series
(SON1612-6).
