:The AX6646BA is an ultra-low dropout LDO regulator that is made by Axelite and RoHS compliant. This is a SOT-23-5L 3.3V fixed output voltage LDO regulator that is designed to deliver up to 500mA output current and features a 1.2V ~ 6.0V input voltage range, 0.2V load regulation, and low quiescent current of only 10uA. This device features a dropout voltage of 160mV at 500mA load, fast transient response, low noise, and a high output accuracy of ±2% over a temperature range of -40°C to +85°C. It also features short-circuit protection, over current protection, and over temperature protection. This LDO is suitable for use in a wide range of applications such as digital cameras, hard disk drives, GSM modules, and other portable electronic applications where low power consumption is essential.
