TPS76328DBVT is a low-dropout adjustable linear regulator featured with ultra low operating current, excellent line and load regulation, fast turn-on time with trimmed output accuracy. It belongs to the LV regulation series, with the output voltage up to 3.3V, and is designed for systems requiring good-performance in low-power consumption values and small package footprint.
Application Field
The TPS76328DBVT is designed primarily for use as a reset controller, providing a precise active-low reset signal when the supply voltage falls below the factory-programmed threshold. It can also be used as an independent low-dropout regulator, providing a regulated voltage when ever a precision source is needed.
It is also suitable for applications such as digital television, HDTV, computing systems, communications systems, networking equipment, automotive electronics and automotive infotainment system, instrumentation systems, and automotive audio systems.
Working Principle
The chip works by using a voltage feedback loop to monitor the output voltage and adjust the gate voltage of the internal p-channel series pass MOSFET, maintaining a precise feedback voltage. This loop is composed of a reference, error amplifier, and a voltage divider connected to the output.
The internal reference can be programmed by two external resistors, providing flexibility for the output voltage of the regulator. An ERROR pin provides external reference voltage for further adjustment for ultimate accuracy.
The on-chip pass MOSFET provides low dropout, low output ripple and high output current for the regulator, supporting up to 1A current that is sufficient for most applications including automotive applications.
Moreover, the TPS76328DBVT also has advanced thermal protection designs such as thermal sensing device, power up/down sequencing protection, and foldback current limiting protection. These protection designs can protect the chip itself and the application circuit when a fault occurs, making the device more reliable.
