RENESAS RAA2118054GP3#JA0 Isolated DC-to-DC Converter, Buck-Step Down, 7 to 80 V Input, 5 V/300 mA Output, 125 °C, TSOT-23-5

RAA2118054GP3#JA0 is an easy-to-use, ultra-low quiescent current (IQ) buck regulator with a wide input voltage range of 7V to 80V and up to 300mA output current. This RAA211805 output voltage is 5V. This device offers comprehensive protections, including VIN UVLO, VOUT OVP, overcurrent, and over-temperature protections. It is used in applications such as general purpose or LDO replacement, industrial power supplies, embedded systems and I/O supplies, E-bikes, power tools, and home/industrial automation.
