The TPS77601PWPRG4 is a high-precision and low-power, low-dropout linear regulator from Texas Instruments. It is part of Texas Instruments\' ongoing effort to provide an extensive portfolio of linear and switching power solutions for a broad array of applications.

The TPS77601PWPRG4 is targeted for space-limited applications, where both low quiescent current and low dropout voltage performance is essential. At supply currents of only 2.2mΩ, the TPS77601PWPRG4 offers easy integration into portable devices, such as mobile phones, digital still cameras, portable medical devices, and other battery-powered products.

Application Field of TPS77601PWPRG4

The TPS77601PWPRG4 is ideal for most low-voltage applications where a stable, low voltage must be maintained. It operates as an ultra-low dropout regulator with minimal noise and very low quiescent current. It also features a low-power shutdown mode, providing further power savings in portable applications. The TPS77601PWPRG4 is available in a variety of fixed output versions, ranging from 0.8V to 3.3V.

It is suitable for applications such as memory retention, digital still cameras, VoIP phones, portable medical devices, portable media players, and other communications and consumer electronics products. Additionally, the TPS77601PWPRG4 can also be used as an input-voltage supply for LDO regulators and other low-voltage applications.

Working Principles of TPS77601PWPRG4

The TPS77601PWPRG4 works by using an internal PMOS transistor to create a voltage reference voltage output. This reference voltage is compared to a voltage threshold, which is adjusted by an internal bandgap reference. If the input voltage falls below the desired output voltage, the PMOS transistor is turned off and the output voltage drops. Conversely, when the input voltage is greater than the output voltage, the PMOS transistor is turned on and the output voltage ramps up. This allows the TPS77601PWPRG4 to regulate the output voltage over a wide range of input voltages.

The TPS77601PWPRG4 also has an internal latching circuitry, which allows for its power-on reset to the internally set voltage. This allows for reliable, safe operation in applications with input voltage fluctuations down to -12V, making it highly suitable for portable applications.

The TPS77601PWPRG4 also contains a slew rate control feature, which allows for precise power-up and power-down regulation. By controlling the slew rate of the output voltage, it keeps the central process unit (CPU) from being affected by nonsynchronous voltage changes. This allows for more reliable voltage control and also helps extend battery life in portable applications.

The device also features a protection circuit that activates when the junction temperature reaches 180 degrees Celsius, preventing the device from burning out. This protection circuit also provides a soft start feature, preventing sudden inrush currents that can damage components.

Conclusion

The TPS77601PWPRG4 is an excellent solution for low voltage applications, and its wide range of features makes it ideal for a variety of battery-powered products. With its low quiescent current and dropout voltage, the TPS77601PWPRG4 offers excellent performance in space-limited applications. Its built-in protection circuit and soft start feature make it a great choice for reliable and safe operation in a variety of situations.
