Comparison List

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).

Supply Current Typ. 1µA (Except the current through CE pull-down circuit)
Standby Mode Typ. 0.1µA
Dropout Voltage Typ. 0.25V (Iout=150mA ,Vout=3.0V)
Temperature-Drift Coefficient of Output Voltage Typ. ±100ppm/°C
Line Regulation Typ. 0.05%/V
Output Voltage Accuracy ±1.2%
Output Voltage Range 1.2V to 3.6V (0.1V steps)
(For other voltages, please refer to MARK INFORMATIONS.)
Input Voltage Range 1.7V to 6.0V
Packages WLCSP-4-P2
Built-in Fold Back Protection Circuit Typ. 40mA
Built-in Auto Discharge Function D Version
Ceramic capacitors are recommended to be used with this IC 0.1µF or more
