1 / 24 page R1180x SERIES 150mA LDO REGULATOR NO.EA-105-0606 1 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 ..................................................1.2V to 3.6V • Built-in Fold Back Protection Circuit .................Typ. 40mA (Current at short mode) • Ceramic capacitors are recommended to be used with this IC 0.1 µF APPLICATIONS • Stable voltage reference. • Power source for electrical appliances such as cameras, VCRs and camcorders. • Power source for battery-powered equipment. |
