Functional Description:

The TPS73525DRVR is a low-dropout (LDO) linear regulator that uses a BiCMOS process to achieve high performance with low power consumption. The LDO regulator architecture provides excellent line and load regulation, as well as low noise and high PSRR.

The TPS73525DRVR has a fixed output voltage of 2.5V. The output voltage is set by an internal voltage reference and a feedback loop. The feedback loop compares the output voltage to the reference voltage and adjusts the gate voltage of the pass transistor to maintain the output voltage at the desired level.

The TPS73525DRVR has a dropout voltage of 280mV (typical) at 500mA output. This means that the input voltage must be at least 280mV higher than the output voltage in order for the regulator to operate properly.

The TPS73525DRVR has a quiescent current of 45uA (typical). This means that the regulator consumes very little power when it is not under load. This makes the TPS73525DRVR ideal for battery-powered applications.

The TPS73525DRVR has a high power-supply rejection ratio (PSRR) of 90dB at 1kHz. This means that the output voltage is very stable even when the input voltage fluctuates. This is important for applications where the input voltage is noisy or unstable.

The TPS73525DRVR has a low noise output of 15uVrms. This means that the regulator produces very little noise, which is important for applications where noise is a critical factor, such as audio and video applications.

The TPS73525DRVR is stable with ceramic capacitors. This makes it easy to design circuits using the TPS73525DRVR, as ceramic capacitors are small and inexpensive.

The TPS73525DRVR is fully specified from TJ = –40°C to +125°C. This means that the regulator can operate in a wide range of temperatures, making it suitable for a wide range of applications.

The TPS73525DRVR is offered in a low-profile, 3 mm × 3 mm SON-8 package and a 2 mm × 2 mm WSON-6 package. This makes the TPS73525DRVR ideal for space-constrained applications.

Conclusion:

The TPS73525DRVR is a low-dropout (LDO) linear regulator that offers excellent performance with low power consumption. It is ideal for battery-powered applications, such as mobile phones, wearable devices, and IoT devices.
