XC6601 Series ETR0335_003 Low Voltage Input LDO Voltage Regulators ■GENERAL DESCRIPTION The XC6601 series is a low voltage input CMOS LDO regulator which provides highly accurate (±20mV) outputs and can supply current efficiently due to its ultra low on-resistance even at low output voltages. The series is ideally suited to the applications which require very low dropout voltage operation and consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a fold back circuit, a thermal shutdown (TSD) circuit, an under voltage lock out (UVLO) circuit and a phase compensation circuit. Output voltage is selectable in 0.05V increments within a range of 0.7V to 1.8V using laser trimming technology and ceramic capacitors can be used for the o
