Product Description

Seamless GO LDO Voltage Regulator

The XC6705 series is a 20V 200mA high-speed LDO regulator featuring Seamless Green Operation.

This series has a low supply current of 1.2μA, despite that it achieves high accuracy, and high ripple rejection. The 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 can be selected from a range from 2.5V to 5.5V (0.1V increments). In addition, the A type has a built-in CL discharge function that can return the charge in the output stabilization capacitor (CL) to the high-speed VSS level in the stand-by mode.

The XC6705 series includes a built-in soft start function to suppress inrush current and overshoot at startup.

Available in SOT-23-5 & USP-4 packages.
