R1180x SERIES
OUTLINE
The R1180x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low
supply current, and low ON-resistance. Each of these ICs consists of a voltage reference unit, an error amplifier,
resistor-net for voltage setting, a current limit circuit which prevents the destruction by excess current, and so on.
The output voltage of these ICs is fixed with high accuracy. B version has a chip enable pin, therefore ultra-low
consumption current standby mode can be realized with the pin.
Since the packages for these ICs are SOT-23-5 (R1180N Series), SC-82AB (R1180Q Series), and SON1612-6
(R1180D Series), therefore high density mounting of the ICs on boards is possible.
FEATURES
• Low Supply Current ..........................................Typ. 1µA(Except the current through CE pull-down circuit)
• Standby Mode...................................................Typ. 0.1µA
• Low Dropout Voltage.........................................Typ. 0.25V (IOUT=150mA 3.0V Output type)
• Low Temperature-Drift Coefficient of Output Voltage Typ. ±100ppm/°C
• Good Line Regulation .......................................Typ. 0.05%/V
• High Output Voltage Accuracy ..........................±2.0%
• Small Packages ..............................................SOT-23-5(R1180N)/SC-82AB(R1180Q)/
SON1612-6 (R1180D)
• Output Voltage ..................................................Stepwise setting with a step of 0.1V in the range of 1.2V to
3.6V is possible
• Built-in Fold Back Protection Circuit .................Typ. 40mA (Current at short mode)
• Ceramic capacitors are recommended to be used with this IC 0.1µF
APPLICATIONS
• Stable voltage reference.
• Power source for electrical appliances such as cameras, VCRs and camcorders.
• Power source for battery-powered equipment.

The relations between IOUT (Output Current) and ESR of an output capacitor are shown above. The conditions
when the white noise level is under 40µV (Avg.) are marked as the hatched area in the graph.
