Torex Semiconductor has launched the XC6237 as a new series of LDO regulator featuring ultra-low current consumption, available in small and thin packages, suitable for IoT devices and wearable devices. The XC6237 series is a CMOS process high-speed LDO regulator IC that achieves low current consumption, high accuracy, and high ripple rejection. 

The output voltage is fixed internally and can be set in the range of 1.2 to 5.0V (0.05V step). It has a Green Operation (GO) function that achieves both a high-speed operation and a low current consumption, and switches automatically between a high speed (HS) mode and a power save (PS) mode depending on the output current. 

At light loads, high efficiency is realised by operating in PS mode with low current consumption, and at heavy loads, high speed operation is enabled by operating in HS mode. This is ideal for applications that require both low current consumption and high speed operation. 

The lineup of 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 of LDO. 

Torex will continue to swiftly develop products that meet market needs and contribute to a richer and more abundant society.
