S-1711F2818-I6T1U is a three-terminal common cathode high-side and low-side linear regulator for fixed 5V output applications. It is produced by Sanyo Energy. This device is a simple and cost-effective linear voltage solution for portable consumer applications.

Application field

The S-1711F2818-I6T1U is ideal for battery-powered consumer applications such as cellular phones, digital cameras, PDAs, and other mobile systems. This device can be used in high-efficiency, and low-noise applications. It also has an adjustable output voltage, which makes it suitable for any application.

It is a single-chip solution, which helps reduce PCB size and cost. It has a wide input voltage range of 3.2V to 6V and can support up to 10A of output current at 5V output. It features low input-output voltage differential of about 70mV, which makes it suitable for low-power DC-DC applications. It is also suitable for both synchronous and asynchronous point-of-load applications.

Working principle

The S-1711F2818-I6T1U is a linear voltage regulator, which means it maintains a constant voltage output. The output voltage is determined by its internal reference voltage and a pair of resistors. A feedback loop is used to close the loop and sense the output voltage, which is then compared to the reference voltage. When the loop is closed, the current distributed to the external resistors and adjust the output voltage.

The S-1711F2818-I6T1U is able to regulate the output voltage in two ways: with an on-chip voltage regulator and with an external voltage regulator. With the on-chip voltage regulator, the device will monitor the output voltage, and any changes in the output voltage will be adjusted by the feedback loop. With the external voltage regulator, the user can manually adjust the output voltage by applying the desired voltage to the control input.

The S-1711F2818-I6T1U also has an integrated over-current protection circuit that prevents excessive current draw when the output voltage is over the specified value. This circuit will reduce the current draw by having a current limit and as a last resort, shutdown the regulator until the overload is removed.

Conclusion

The S-1711F2818-I6T1U is a three-terminal common cathode high-side and low-side linear regulator for fixed 5V output applications. It is an ideal choice for battery-powered consumer applications such as cellular phones, digital cameras, PDAs and other mobile systems. It has an adjustable output voltage, wide input voltage range, low input-output voltage differential, and integrated over-current protection circuit. It is also suitable for synchronous or asynchronous point-of-load applications.
