TPS7A3001DGNR Key Specifications

● Maximum Power Dissipation

The TPS7A3001DGNR can put out a maximum of 1830 mW of power. This number shows how much power the regulator can safely take without getting too hot. It is important to pay attention to this number to make sure the machine works right and doesn’t get too hot.

● Overall Accuracy

The TPS7A3001DGNR is accurate to within 1.5% overall. This measure shows how far the output voltage is from what is wanted. With a high level of accuracy, the regulator controls the voltage in an exact and consistent way, making sure that the output voltage stays within the range that was set.

● Dropout Voltage

The dropout voltage is the difference in voltage between the regulator’s input and output that must be at least this much for the regulator to keep the output voltage at the required level. The dropout voltage of the TPS7A3001DGNR is 0.216 V at 100 mA and 0.325 V at 200 mA. This standard is very important because it tells us the minimum input voltage that must be present for voltage regulation to work properly.

Adjustable Output Voltage Range

The output voltage of the TPS7A3001DGNR can be changed from -33 V to -1.166 V. This wide range gives people the freedom to change the output voltage to meet their own needs. By using resistors or other voltage-setting parts on the outside of the regulator, the output voltage can be set exactly within the range given.

The output voltage range can be changed, which gives you more freedom when designing and powering different electrical systems. It can be changed to meet the power needs of different parts, ensuring that they work well together and run at their best. The TPS7A3001DGNR’s adjustable output voltage range gives it flexibility and adaptability, whether it’s to power specialized devices or to meet the needs of a specific application.

This function lets designers fine-tune the voltage levels, get the most out of them, or meet the voltage requirements of their application. It gives you more control over the power source, so the TPS7A3001DGNR can be used in a wide range of situations where you want to change the voltage.
