STMicroelectronics Fixed LDO Voltage Regulator 3.3V 1A SOT-223-3
Fixed 3.3V LDO voltage regulator by STMicroelectronics. 1A output, 1.15V dropout, SOT-223-3 package. Ideal for stable power supplies.
The STMicroelectronics Fixed LDO Voltage Regulator is a high-performance, low dropout positive voltage regulator designed to deliver a stable 3.3V output. Capable of providing an output current of up to 1A, this device is perfectly suited for a wide range of power management applications requiring reliable and consistent voltage regulation.
Featuring a typical dropout voltage of just 1.15V at 1A output (at 25°C), this regulator ensures efficient operation even when the input voltage is only marginally higher than the required output. It also boasts a very low quiescent current of 5mA typical at 25°C, which minimises power waste and enhances overall system efficiency.
For enhanced durability and safety, the regulator incorporates internal current and thermal limiting protection. Stability is achieved with the addition of only a 10µF capacitor, simplifying circuit design and reducing the overall component count on your printed circuit board.
Designed for surface mount applications, it comes in a compact 3-pin SOT-223-3 package. The device operates reliably across a broad temperature range from 0°C to 125°C and accepts an input voltage range from 5.3V to 10V.
