The XC6413 series are highly precise, low noise, positive voltage LDO regulators with voltage detector manufactured using CMOS processes. More the series achieves high ripple rejection and low dropout and consists of a voltage reference, an error amplifier, a current limiter and a phase compensation circuit plus a driver transistor. Detect voltage is selectable in 0.1V increments within a range of 0.9V ~ 6.0V and VR output voltage is selectable within a range of 0.9V~5.5V. The series is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the series. The current limiter's foldback circuit also operates as a short protect for the output current limiter and the output pin. The series provides options to choose suited functions to each systems such as detector monitoring, detector output logic, CE and EN pin input logic, internal pull-up / down resistance, power ready (PR) function. The IC's internal regulator circuitry can be in stand-by mode by the EN function with the XC6413 A to C series. The whole IC's circuitry can be in stand-by mode via CE function with the XC6413D series (semi-custom). In the stand by mode, power consumption can be greatly reduced. XC6413 A and B series has toggle operation function. The regulator output can be OFF when XC6413B series detect voltage (semi-custom). XC6413E series can monitor the other power source by using VSEN pin (semi-custom).
