20V Input Voltage, 200mA Low Supply Current 1.2μA, High Speed Voltage Regulator

The XC6705 series is a high-speed LDO regulator IC using CMOS process. This series are low supply current 1.2μA, despite achieves high accuracy, and high ripple rejection. Internal circuitry includes a reference voltage supply, error amplifier, Pch driver FET, current limit circuit, thermal shutdown circuit, and phase compensation circuit.

The output voltage is fixed internally by laser trimming, and product selections from 2.5V to 5.5V (0.1V increments) are available. In addition, the A type is built-in with C_L discharge function that can return the charged in the output stabilization capacitor (C_L) to the high-speed V_SS level in the stand-by mode.

The XC6705 series is built-in with soft start function to suppress inrush current and overshoot at startup. The series start up the output voltage in 1.0ms.
