TOREX XC6602B111MR-G

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 (CL). The inrush current (IRUSH) from VIN to VOUT for charging CL at start-up can be reduced and makes the VIN stable. The soft-start time is optimized internally. 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 (CL) to be discharged via the internal switch. As a result the VOUT pin quickly returns to the VSS level. The CE pull-down function keeps the IC to be in stand-by mode even if the CE pin is left open.
