RAA2118034GP3#JA0

RAA2118034GP3#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. RAA211803 has a fixed output voltage of 3.3V. 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.

• Input supply range from 7V to 40V
• Pre-bias, monotonic, and smooth start-up, accurate EN threshold
• VIN quiescent current is 5.5µA typ at (EN = VIN = 80V, VOUT = 3.3V or 5V, no load operation)
• Shutdown current is 0.3µA typical at (EN = 0V, VIN = 24, no switching)
• Minimum on-time is 75ns typical at (VIN = 20V, TA = +25°C)
• On-resistance is 2.9 ohm typical at (VIN = 20V, TA = +25°C)
• Current limit is 0.75A typical at (VIN = 12V, TA = +25°C)
• Current limit prop delay is 50ns typical at (TA = +25°C)
• Operating temperature range from -40°C to +125°C
• TSOT-23 package
