XC6602 Series ETR03045-006 1A, 0.5V Low Input Voltage, High Speed LDO Regulator GENERAL DESCRIPTION The XC6602 series is a low voltage input (0.5V) operation and provides high accuracy 15mV/20mV and can supply large current efficiently due to its ultra low on-resistance even at low output voltages. The series is ideally suited to the applications which require high current in low input/output voltages and consists of a Nch driver transistor, a voltage reference, an error amplifier, a current limiter, a fold-back circuit, a thermal shutdown (TSD) circuit, an under voltage lock out (UVLO) circuit, a soft-start circuit and a phase compensation circuit. Output voltage is selectable in 0.1V increments within a range of 0.5V to 1.8V using laser trimming technology and ceramic capacitors can be used for the output stabilization capacitor (C ). The inrush current (I ) from V to V for charging C at L RUSH IN OUT L start-up can be reduced and makes the V stable. The soft-start time is optimized internally. IN The CE function enables the output to be turned off and the series to be put in stand-by mode resulting in greatly reduced power consumption. At the time of entering the stand-by mode, the series enables the electric charge at the output capacitor (C ) L to be discharged via the internal switch. As a result the V pin quickly returns to the V level. OUT SS The CE pull-down function keeps the IC to be in stand-by mode even if the CE pin is left open.
