700mA High Speed LDO Regulators, Voltage Detector Function
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 0.05V increments with in 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 can delay the detector output: the delay time can be controlled by the use of an external capacitor.
