U3V9FX Step Up Voltage Regulators

Step‑up voltage regulators raise a low supply voltage to a higher, stable output that can power sensors, microcontrollers, motor drivers and other circuitry where the required voltage exceeds the source. They accept a minimum input of around 2.6 V and can deliver up to about 900 mA, making them suitable for battery‑powered projects that need 5 V, 12 V, 15 V, 18 V, 24 V or similar levels. Performance is limited by thermal dissipation, so the achievable current varies with the input voltage and must be checked against the device’s heat‑sinking capability. Their compact form factor and standard pinout simplify board layout and integration with common development platforms, while built‑in regulation ensures reliable operation across a range of load conditions.
