The XC6403 includes a LDO voltage regulator and voltage detector in one single-chip package. With a power consumption of 30 μA (less than 0.01 μA in standby), the XC6403 is ideal for Bluetooth and WLAN. The series provides regulated low-noise outputs, and can be configured to monitor various parts of the circuit including the input, battery level check; and the output, similar to a power ‘OK’ function. Designers can select active high or active low for the EN/CE logic, with or without a built-in pull up/down resistor.
