R1154x Series 150 mA Voltage Regulator (Wide Input Voltage Range) No. EA-100-171024 OUTLINE The R1154x is a voltage regulator (VR) featuring 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. The regulator output voltage is fixed in the R1154xxxxB, while adjustable type is the R1154x001C. The 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.
