Portfolio of High Performance, Low Iq Buck Regulators for LDO Replacement
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.
