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 comprehensive protections, including VIN UVLO, VOUT OVP, overcurrent, and over-temperature protections. The devices are offered in a TSOT23-5 package. Applications ▪ General purpose or LDO replacement ▪ Industrial power supplies ▪ Embedded systems and I/O supplies ▪ E-Bikes, Power Tools ▪ Home/Industrial Automation Datasheet Features ▪ 7V to 80V input supply range ▪ Up to 300mA output
