RAA211805 Overview
RAA211803, RAA211805 80V, 300mA, 5.5µA IQ DC/DC Step-Down Regulator The RAA211803 and RAA211805 are easy-to-use, ultra-low quiescent current (IQ) buck regulators with a wide input voltage range of 7V to 80V and up to 300mA output current. RAA211803 has a fixed output voltage of 3.3V, and the RAA211805 output voltage is 5V. The devices offer prehensive protections, including VIN UVLO, VOUT OVP, overcurrent, and...
