The RAA211803 is a tiny, easy-to-use, ultra-low quiescent current (IQ) buck regulator with a wide input voltage range of 7V to 80V and up to 300mA of output current with a fixed 3.3V output.
Available in a TSOT23-5 package, the device offers comprehensive protections, including VIN undervoltage lockout (UVLO), VOUT overvoltage protection (OVP), overcurrent protection, and over-temperature protection.

The RAA21140x and RAA21180x families of bucks are simple to use and cost-effective while offering more than 15x less power loss of similar output rating LDOs (depending on operating conditions) with ultra-low 4uA Iq at zero loading conditions, making it ideal for powering always-on standby housekeeping MCUs or sensors. These bucks are ideal for general LDO replacement in applications such as industrial & home automation, eMobility solutions, energy storage, cordless power tools, and appliances.
