ON Semiconductor NCP1117DT33RK Voltage Regulator

The NCP1117DT33RK from ON Semiconductor is a robust and reliable fixed output voltage regulator designed to provide a stable 3.3V output. This linear voltage regulator is part of the NCP1117 series, which is well-known for its high-performance characteristics in a wide range of applications. The device is particularly suitable for use in post-regulation scenarios, where a low dropout voltage is essential to maintain a stable output despite variations in input voltage or load conditions.

The NCP1117DT33RK is capable of delivering up to 1A of output current, making it an excellent choice for powering moderate to high-current devices. Its dropout voltage is typically 1.2V at full load, which allows for efficient operation even when the input voltage is relatively close to the output voltage. This feature is particularly useful in battery-operated devices where maximizing battery life is crucial.

One of the key features of this voltage regulator is its built-in thermal shutdown and current limit protections, which safeguard the device and the connected components from damage due to excessive heat or current. The thermal shutdown feature automatically turns off the regulator if the internal temperature exceeds a safe threshold, while the current limit protection prevents the output current from exceeding the maximum rated value.

The NCP1117DT33RK comes in a TO-252 (DPAK) package, which is known for its compact footprint and excellent thermal performance. This package allows for efficient heat dissipation, ensuring reliable operation even under high load conditions. Moreover, the device is designed to be compatible with high-speed assembly equipment, which makes it an ideal choice for mass production environments.

Overall, the NCP1117DT33RK from ON Semiconductor is a high-quality voltage regulator that offers a fixed 3.3V output with excellent load and line regulation characteristics. It is suitable for a wide variety of applications, including consumer electronics, computer peripherals, and industrial equipment, where a stable and reliable power supply is necessary.
