TPS7333QPWR Application Field and Working Principle

The TPS7333QPWR is a dual 1 A low-dropout (LDO) linear voltage regulator with ultra-low quiescent current designed for applications that must function in a power-constrained environment. This device features a controlled start-up circuit and is capable of powering a wide range of applications, including tablets, laptop systems, wearables, and peripherals. Thanks to its small size, wide temperature range, and low profile WLCSP package, the TPS7333QPWR can also be used in space-constrained and automotive systems. The device offers high accuracy and excellent load regulation over various load steps from 1 mA to 1 A.

The TPS7333QPWR is a PMIC (power management integrated circuit) that operates as a voltage regulator. It converts a higher input voltage into a lower output voltage using linear regulation. The input and output voltages are adjustable so the device can be used for a wide range of applications. The device is capable of regulating from 0.6 V to 5.5 V with an ultra-low quiescent current of 3 µA. It features a controlled start-up circuit and is designed to be extremely efficient, with a typical efficiency of over 90%.

The TPS7333QPWR is designed to enable long battery life and low power draw in a range of applications. The device features an automatic low-battery cutoff circuit which can be used to limit the voltage at the input of the regulator. This is useful in applications where the power supply voltage may drop below the regulated output voltage to ensure the device does not run overvoltage. It also has a Soft-Start circuit which prevents inrush current from the input source by gradually increasing the output voltage over a controlled ramp time. This helps to reduce stress on the power supply and ensures that the device does not go into over-current or overtemperature conditions.

The TPS7333QPWR also features an output capacitor which helps to improve load regulation, reduce output voltage ripple and provide transient voltage suppression during load steps. The device includes internal current-limit protection which helps to protect against over-current conditions and the output voltage can be adjusted using an external resistor divider. The device is also protected against over-temperature conditions, short-circuit and reverse-current faults.

The TPS7333QPWR is an ideal solution for applications that require low power consumption and high accuracy. It is designed to provide excellent load and line regulation and features a wide input voltage range, ultra-low quiescent current, and low output ripple. The device is available in a compact, 2-mm x 2-mm WLCSP package which provides a very small form factor ideal for space-constrained applications. With its high efficiency, wide temperature range and comprehensive protection, the TPS7333QPWR is an excellent choice for a range of portable applications where power efficiency and accuracy are essential.
