The latest LDO regulators from Torex have low current consumption, making them suitable for IoT devices and wearable devices.

Based on a CMOS process, the high speed LDO regulator IC achieves low current consumption, high accuracy, and high ripple rejection, claims the company.

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 high speed operation and a low current consumption, says the company. It 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.

They are available in small and thin USPQ-4B05 and general-purpose SSOT-24 packages. Low ESR capacitors such as ceramic capacitors can be used at the output of the LDO.
