The XC6504A181MR-G from Torex Semiconductor is an ultra-low quiescent current LDO voltage regulator with a typical quiescent current of only 0.6uA. It features a typical dropout voltage of 250mV and a wide range of load current capabilities, up to 500mA. It is an adjustable output voltage device, with an output voltage range of 0.8 – 5.0V. It has programmable soft start/stop, allowing it to be used where a slower ramp-up time is desired. Additionally, it features thermal protection and output short-circuit protection, providing system safety and reliability. It is a space-saving solution, with a tiny 4-pin SOT-23 package. The XC6504A181MR-G is ideal for battery-powered portable devices.
