Working Principle

TPS71712DCKTG4 is designed to step down the input voltage from a source such as a battery or external power supply to a lower level needed by the load. The linear regulator operates with a minimum of external components, consists of a NMOS pass transistor, error amplifier, temperature-compensated voltage reference, light-load current source, start-up circuit and power-on reset.

It provides a precise output voltage range for a wide variety of applications. The adjustable reference terminal sets the output voltage by voltage divider, and the error amplifier compares the output voltage with low noise-regulated reference. Bypass capacitor suppresses high-frequency line noise and provides over-current protection via the PWM-mode. It provides short-circuit protection and thermal shutdown to prevent damage from excessive heat.

The TPS71712DCKTG4 is designed to minimise power loss and noise in DC/DC power converters, boosting efficiency. The current-limited output ensures any surge-related current is limited, so the system works reliably over a wide temperature range.

Conclusion

TPS71712DCKTG4 is an excellent choice for applications requiring a low-cost voltage regulator that can accurately and efficiently deliver a wide range of output voltages. It provides excellent noise-rejecting performance and reliable low-dropout performance over a wide temperature range. By maintaining a low cost and small size, it is ideal for applications ranging from medical devices to automotive.
