The XC6216B5028R-G is a low-dropout (LDO) voltage regulator manufactured by Torex Semiconductor. The regulator features 28-volt (V) input voltage, an ultra-low dropout voltage of 330mV, a maximum output voltage of 5V, and a maximum output current of 800mA. It is features an ultra-low quiescent current of 25µA at no load, fast transient response, and a low noise profile. Its high-efficiency design comes with built-in protection circuits, including thermal shut-down, over-voltage protection, and reverse current protection. The regulator is offered with a TSOP-6 package and an operating temperature range of -40°C to +85°C.
