XC6402

XC6402 Series High Current, High Speed LDO Regulators, Voltage Detector Function ETR1001_006 ■GENERAL DESCRIPTION The XC6402 series are precise, low noise, high current, positive voltage low dropout regulators with built-in voltage detector. They are fabricated using Torex’s CMOS process. The series features a voltage reference, an error amplifier, a current limiter, a voltage detector, and a phase compensation circuit plus a driver transistor. The output voltage of the LDO and detect voltage of the detector is selectable in 50mV increments within the range of 0.8V to 5.0V. With a low ON resistance driver transistor built-in, batteries can be used until input-output voltage differential is minimal and can accordingly be used for a longer time. The series is also compatible with low ESR ceramic capacitors which give added output stability. The series provides options to the user to select from a variety of circuit features, such as detector monitoring, detector output logic, EN pin input logic, and internal pull-up / down resistance (semi-custom). The IC's internal regulator circuit can be placed in stand-by mode via the EN function (XC6402C series). In the stand-by mode, power consumption is greatly reduced. The XC6402F series offers the option of a delay on the detector output: the delay time can be controlled by the use of an external capacitor. ■APPLICATIONS ●Optical disk drive ●Magnetic disk drive ●Digital still cameras / Camcorders ●Digital audio equipments ●Multi-fun...
