FAQs

What is TPS74901RGWT?

The TPS74901RGWT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It is designed to provide a stable output voltage with minimal voltage drop, making it ideal for applications requiring precise voltage regulation in power management circuits.

How Does TPS74901RGWT Work?

The TPS74901RGWT regulates the output voltage by comparing the reference voltage to the feedback voltage and adjusting the pass device accordingly. It maintains a stable output voltage even when there are fluctuations in the input voltage or current, providing a reliable power supply for connected components.

How Many Pins does TPS74901RGWT have and What are the Functions of the Pinout Configuration?

The TPS74901RGWT is housed in a 20-pin VQFN (Very Thin Quad Flat No-Lead) package. The pinout configuration includes:

  • VIN: Input voltage pin.
  • VOUT: Output voltage pin.
  • GND: Ground pin.
  • EN: Enable pin to turn the regulator on or off.
  • TRIM: Pin for adjusting the output voltage.
  • PG: Power Good output pin for monitoring the output voltage.

What are the Pros and Cons of TPS74901RGWT?

Pros:

  • Low Dropout Voltage: Maintains a stable output voltage even when input voltage is close to the output voltage.
  • Low Quiescent Current: Operates with minimal standby current, suitable for power-sensitive applications.
  • Thermal Protection: Includes built-in thermal shutdown protection to prevent overheating.
  • Wide Input Voltage Range: Supports a wide range of input voltages for versatile applications.
  • Compact Package: The VQFN package is space-efficient and offers good thermal performance.
