R1154x Datasheet | RICOH

features of high output voltage accuracy and ultra-low supply current. A peak current limit circuit, a short current limit circuit, and a thermal shutdown circuit are built in the R1154x series. The regulator output voltage is fixed in the R1154xxxx B, while adjustable type is the R1154x001C. Output voltage accuracy is ±2.0%. Since the packages for these ICs are DFN1616-6, SOT-23-5, and SOT-89-5, high density mounting of the ICs on boards is possible. FEATURES - Supply Current Typ. 5.0μA - Standby Current Typ. 0.1μA - Output Voltage Accuracy ±2.0% - Wide Output Voltage Range 2.5V to 12.0V (0.1V steps) (xxx B) adjustable in the range of 2.5V to VIN or 24.0V (001C) (For other voltages, please refer to MARK INFORMATIONS.) - Input Voltage Max. 24.0V - Output Current Min. 140m A (VIN=VOUT+2.0V, 2.5V Output type) Min. 150m A (VIN=VOUT+2.0V, 3.0V Output type) - Package DFN1616-6, SOT-23-5, SOT-89-5 - Built-in Peak Current Limit Circuit - Built-in Short Current Limit Circuit - Built-in Thermal Shutdown Circuit APPLICATIONS - Power source for home appliances such as refrigerators, rice cookers, Electronic water warmers, etc. - Power source for car audio equipment, car navigation system, and ETC system. - Power source for notebook PCs, digital TVs, cordless phones, and LAN system. - Power source for copiers, printers, facsimiles, and scanners.
