NCP1117ST25T3 is a precision voltage regulator designed for low power applications. It can maintain a constant output voltage, over a wide range of input and output voltages, in order to accurately regulate the output current for accuracy and power savings in low power applications. This voltage regulator is available in four different output voltage levels: 2.25V, 2.5V, 3.3V, and 5.0V.

NCP1117ST25T3 Application Field

The NCP1117ST25T3 is ideally suited for use in medium power applications. It is ideal for applications such as smartphones and other portable devices, where power consumption considerations are a priority. It can maintain the accuracy of system voltages and currents, while reducing power losses. It is also suitable for power supplies, DC-DC converters, and battery-powered equipment.

NCP1117ST25T3 Working Principle

The NCP1117ST25T3 works by providing a constant voltage across the output terminals. It does this by monitoring the voltage across the input prior to regulating it to a predetermined level. This is done by the regulator’s internal circuitry, which adjusts the output voltage according to the input voltage. The output voltage is then regulated to the selected voltage by adjusting the resistance to the feedback pin, along with the internal bandgap reference. This allows for precise control over the output voltage. Additionally, the output voltage can also be adjusted with an external resistor.

The NCP1117ST25T3 also provides over-voltage and over-current protection, by instantly shutting down the output when the voltage exceeds the maximum set voltage. This helps to protect the circuits from over-voltage or over-current conditions. Additionally, the voltage regulator also includes thermal protection, which helps protect the device from overheating or excessive current flow.

The NCP1117ST25T3 has excellent load and line regulation with a wide input voltage range and a low output ripple voltage. A unique feature of this voltage regulator is the standby feature, which allows the input voltage to be lowered while the output still remains regulation. This helps to improve the overall efficiency of the system.

The NCP1117ST25T3 is available in through-hole and surface mount packages, which provides easy access for engineers when integrating the device into their design. It is also tolerant to a wide range of environmental conditions, providing the reliability required for low power applications.

Conclusion

The NCP1117ST25T3 is an ideal choice for applications such as smartphones, power supplies and DC-DC converters as it provides an accurate and regulated voltage output to the system. It can also provide over-voltage and over-current protection, as well as thermal protection. The device is also tolerant to a wide range of environmental conditions, and can provide a low output ripple voltage. Additionally, the device offers a standby feature, which helps to improve the overall efficiency of the system. Overall, the NCP1117ST25T3 is a very efficient and reliable voltage regulator that is suitable for a wide variety of low power applications.
