The TPS71728DSET is an LDO Linear Voltage Regulator from Texas Instruments. It is suitable for various application fields including modems and mobile phone applications, industrial and automotive applications, computer peripherals, general consumer applications and audio/video equipment.

The TPS71728DSET has been specifically designed to provide constant output voltage and excellent power supply rejection ratio (PSRR). It also features low quiescent current and very high peak current capability, enabling conversion efficiency under high-load conditions. This device is offered in a TDFN 5-pin package.

The TPS71728DSET is a low dropout (LDO) linear voltage regulator with an integrated PMOS pass transistor. The output voltage is programmed using an external resistor divider. The pass transistor lets the device preserve a very low output voltage drop when operated over a wide input voltage range, allowing for good efficiency. The output voltage is also regulated by reducing the drain current of the PMOS device.

The device uses an error amplifier to compare the output voltage with the reference voltage. The internal oscillator modulates the gate drive of the pass GATE transistor, thus allowing for good load and line transient response. The N-FET pass transistor also minimizes the quiescent current in the output circuit.

The TPS71728DSET also has excellent current limit, short-circuit protection, thermal shutdown, and reverse current protection. The device is available in 8-pin SOIC and TDFN packages and an extended input voltage range of 2.3V to 6V. The output voltage is adjustable from 0.8V to 3.6V, and it can handle output currents up to 1A.

In summary, the TPS71728DSET is an ultra-low dropout linear voltage regulator specifically designed for efficient, high-performance power supply applications. The device offers excellent power supply rejection ratio, low quiescent current and high peak current capability, enable excellent performance and efficient operation. It is suitable for various applications including modems and mobile phone applications, industrial and automotive applications, computer peripherals, general consumer applications and audio/video equipment.
