Torex Semiconductor, Ltd. Voltage Regulators - Linear XC6224B291MR-G

The XC6224B291MR-G is a high-speed linear voltage regulator from Quarktwin Technology Ltd. designed for low voltage operation, with a maximum output current of 150mA. It operates within an input voltage range of 1.2V to 3.6V and features high accuracy of ¬±1.5% for output voltages between 1.25V and 3.0V, and ¬±20mV for output voltages from 0.8V to 1.20V. The device is characterized by low power consumption of 33OºA (typical) and a stand-by current of just 0.1OºA. The XC6224B291MR-G offers high ripple rejection of 70dB at 1kHz and a low dropout voltage of 210mV at 150mA output. It includes integrated protection circuits such as current limiting and short circuit protection, along with an active high ON/OFF control feature. The regulator is packaged in a compact USPN-4B02 form factor measuring 0.75mm x 0.95mm, making it suitable for applications in mobile devices, digital cameras, and wireless communication equipment. The device is also compliant with EU RoHS standards, ensuring it is environmentally friendly.
