Overview

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 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
