R1183Z

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).

ABSOLUTE MAXIMUM RATINGS Absolute Maximum ratings are threshold limit values that must not be exceeded ever for an instant under any conditions. Moreover, such values for any two items must not be reached simultaneously. Operation above these absolute maximum ratings may cause degradation or permanent damage to the device. These are stress ratings only and do not necessarily imply functional operation below these limits. 4 R1183Z ELECTRICAL CHARACTERISTICS • R1183Zxx1B/D Topt=25°C Symbol VOUT Item Output Voltage*1 Conditions VIN=Set VOUT+1V IOUT=1mA VIN−VOUT=1.0V (VOUT > 1.5V) = If VOUT 1.5V) = If VOUT 1.5V) = If VOUT 1.5V) = If VOUT
