NCP1117ST20T3 is an integrated linear voltage regulator that belongs to the family of PMIC – Voltage Regulators – Linear. It is an advanced voltage regulator designed to provide an adjustable output voltage ranging from 1.2V to 5.0V. NCP1117ST20T3 features a wide input voltage range of up to 11V, and delivers a maximum output current of up to 1.2A. It is capable of operating at a maximum ambient temperature of 85°C. It is available in a compact 8-pin SOP package.

It is designed to meet the needs of most digital and analog circuit applications. The device has the ability to regulate an adjustable DC output voltage in response to the error amplifier’s output voltage. It utilizes an advanced internal circuit design to minimize the number of external components, providing a highly consistent output voltage over a wide temperature range. NCP1117ST20T3 is particularly suitable for low current applications such as artificial intelligence (AI) and Internet of Things (IoT).

The device has several on-board features that enable it to remain stable over varying loads. Its built-in feed-forward control ensures that the output voltage remains stable over load and changes in the input voltage. Its output voltage is also controlled by the on-board error amplifier. The wide load operation range enhances load transient response. Additionally, it supports both continuous and discontinuous mode operation.

The device has a simple and easy to use circuit structure. Firstly, the input voltage is applied to the feedback winding of an internal transformer, and then the output voltage is obtained at its secondary winding. Furthermore, an error amplifier is connected to the output terminals. The output voltage is regulated by this error amplifier and a control voltage. The voltage applied to the control terminal determines the magnitude of the output voltage.

In the case of low emission requirements for the output voltage, the NCP1117ST20T3 can be used. It is suitable for applications where regulated output voltage is required, like in AC adapters, computers, smart phones, notebooks and cameras etc. It is also used in various automatic control systems, as it allows for remote signalling of temperature changes.

NCP1117ST20T3 is a highly efficient voltage regulator that can be used for a variety of applications. Its compact package size, wide input voltage range and highly efficient output operation make it an ideal choice for a wide range of system designs. In addition, its built-in features and easy to use circuit structure provide a high level of flexibility and make it a reliable solution for different types of applications.
