XC6241 Series

Ultra-Low Supply Current 0.6µA High Speed Voltage Regulators

The XC6241 series are CMOS process high-speed voltage regulator ICs with low supply current, high accuracy, and high ripple rejection. The output voltage is fixed internally and can be set in the range of 1.2V to 5.0V.

It has a Green Operation (GO) function that achieves both high-speed operation and low supply current, and switches automatically between high speed (HS) mode and power save (PS) mode according to the output current. At light load, high efficiency is realized by operating in PS mode with low supply current, and at heavy load, high-speed operation is enabled by operating in HS mode. This is ideal for applications that require both low supply current and high-speed operation.

The lineup package of the small and thin USPQ-4B05 and general-purpose SSOT-24 are available for various applications. Low ESR capacitors such as ceramic capacitors can be used at the output capacitors.
