TPS76725QPWP

TPS76725QPWP is a dual-channel high-accuracy linear voltage regulator chip developed by Texas Instruments. It is an ultra-low voltage voltage regulator that supports a variety of input voltages and a typical dropout voltage of only 200mV, which makes the device an ideal solution for systems with a maximum output current of 200 mA.

The devices operate over a wide input voltage range from 3.2V to 6V. It supports two output voltages, each of which can be adjusted from 0.6V to 5.0V, with a typical accuracy of less than 1%. It also supports I2C interface, allowing the output voltage to be regulated dynamically. The devices can be reset using the RST/BUSY pin or through the I2C interface. All these operations are monitored by the OC/UV overlapping alert pin. Through a complete set of protectors and integrators, the device can handle various fault conditions without damage.

The device includes two internal high-accuracy linear regulators and the external bandgap references. Where the external reference passes the current through the resistor so it can be adjusted by the voltage drop across the resistor. This voltage equals the voltage needed to regulate the output voltage of the regulator. The working principle of the regulator can be said to be using the voltage comparison technique to adjust the channel current shunt regulator and then regulate the output voltage precision. In addition, its specified operating temperature range is -40°C to 125°C.

Due to its wide range of operating temperature and high accuracy voltage regulation, TPS76725QPWP can be used for a variety of applications, including but not limited to, FPGA and DSP power supplies, microcontroller and embedded systems, telecom systems, LCD monitors and portable devices. The combination of TPS76725QPWP and TI\'s other products makes it an ideal solution for applications requiring external or low voltage regulators.
