TPS77625PWPRG4 is a single-channel linear voltage regulator designed for those applications demanding low-noise output and a low dropout voltage (LDO). As a PMIC (Power Management IC) voltage regulator device, it offers low dropout voltage capability and a range of operating voltage, making it suitable for systems requiring high accuracy performance.
The TPS77625PWPRG4 comes in small VPDSON or SC-70 package, making it suitable for a wide range of applications such as mobile communications, automotive and medical. It is a cost-effective, power efficient device featuring an adjustable output voltage range of 2.5V to 6V.
In addition to being a voltage regulator device, TPS77625PWPRG4 also contains other features like over-temperature and under-voltage detection, as well as a Power Enable function to ensure a clean power source to the system.
The application field for the TPS77625PWPRG4 is an extremely broad, and can be applied to many areas of power management, especially those with high accuracy requirements. It can be utilized in providing power to low-noise, highly accurate analog circuits, such as mixed-signal, real-time clock (RTC), WLAN, digital-audio, and telecommunication systems. It is also suitable for USB bus applications, owing to its low-dropout voltage and low quiescent current.
The working principle of the TPS77625PWPRG4 is that of most linear regulators, where the output voltage is set by the input voltage and regulated by either a series pass element (transistor or FET) or a shunt pass element (resistor). This device uses a shunt pass element (resistor) to provide low dropout voltage (<350mV at full load) from a fairly wide input voltage range, from 2.5V to BE/Ki.
In order to achieve the desired output voltage, the Vref pin of the device serves as the reference voltage for the internal resistor divider. The feedback voltage is generated through an external resistor divider from the output of the device and compared with the Vref. When the two voltages mismatch, an internal error amplifier adjusts the gate voltage of the pass element to the required level and regulates the output voltage.
The quiescent current of TPS77625PWPRG4 is remarkably low, with a maximum of 120μA, ideal for battery-powered applications. It also has a thermal shutdown protection and an over-current protection function that can be enabled through the EN pin.
The TPS77625PWPRG4 is a low dropout linear voltage regulator which can be used in applications requiring high accuracy and low noise. With its low quiescent current, adjustable output voltage range, and its integrated over-temperature and under-voltage detection, it is an ideal device for a wide range of power management applications.
