The R1154x series are CMOS-based voltage regulator (VR) ICs. The R1154x has 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 R1154xxxxB, 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.
