PMIC - Voltage Regulators - Linear

The TPS76338DBVTG4 is a highly efficient, low-power, 1.8-V linear regulator with a wide input voltage range and adjustable output within a 1.2-V to 3.6-V range. It is designed to support a wide range of system applications, including mobile phones, audio systems, sensors, and automotive systems.

Application Field

The TPS76338DBVTG4 can be used in a variety of applications. It is ideal for powering low-voltage, low-power systems such as mobile phones, audio systems, sensors, and automotive systems. It provides ultra-low quiescent current (15µA typ, making it suitable for battery-operated systems. It also provides ultra-low noise and output ripple, making it an ideal choice for powering sensitive components.

Working Principle

The TPS76338DBVTG4 is a low-voltage linear regulator, utilizing an internal PMOS transistor to regulate the output voltage. The device features an adjustable output voltage, with an input voltage range of 1.2V to 3.6V. The output voltage can be adjusted via the FB pin (feedback pin). A voltage reference is required to connect to the FB pin, and the voltage reference can be connected to ground or any other voltage level.

The device has an Enable pin, which can be used to disable the device when the input voltage is lower than the desired output voltage. This allows the device to know when the input voltage is insufficient for the desired output voltage and allow for further power savings. The device also has a Preferred Mode pin, which enables the device to automatically reduce the quiescent current (save power) when the voltage is close to the output voltage.

The TPS76338DBVTG4 can deliver a maximum output current of 200mA and features excellent line/load regulation, low quiescent current, and low output noise/ripple. It has logic-level enable/disable control and provides protection features like thermal shutdown and over-voltage protection.
