The TPPM0303DR is a low drop-out (LDO) linear voltage regulator featuring ultra-low quiescent current, fast transient response so it is ideal for portable applications. It has an adjustable output voltage and output current up to 1.5A. This voltage regulator offers common features such as EN/UVLO, thermal shutdown, and reverse current protection. It also provides most up-to-date features such as soft start, low noise, and built-in surge protection.

Application Field

The TPPM0303DR LDO linear voltage regulator is designed for use in a wide range of power management applications including battery powered products, portable communication devices and any other applications which require extended battery life. More specifically, its ultra-low current consumption, high efficiency, and accurate output voltage make it ideal for applications in battery-driven mobile phones, digital cameras, audio systems, and also general purpose power supplies.

The built-in reverse current protection and over-temperature protection make the TPPM0303DR an ideal choice for powering sensitive digital devices that require very little noise and disturbance on output voltage stability, while stable output voltage is maintained over time. Apart from that, its fast transient response time offers fast and reliable power supplies under harsh electrical conditions. The ease of use and small package size make the TPPM0303DR a cost-effective solution for portable applications.

Working Principle

The TPPM0303DR regulates the output voltage within ±1.5% accuracy by utilizing external sense resistors, enabling a low input voltage variation. The voltage applied to the sense resistors “Trim” pin adjusts the output voltage set point precisely.}

In addition, the device switches off the internal FET for EN triggered logic low input voltage. The EN pin has an ultra-low current (10nA typical) for permissive turn-on. When the input voltage is below the under-voltage lock-out (UVLO) threshold, the device will be locked out and the FET is shutdown. In addition, if the temperature is detected as near to the thermal limit (TSD), the device will shut down the FET automatically.

The TPPM0303DR provides fast load transient response with fast enable mechanism. The soft start function allows non-over shoot startup time and inrush current limiting. It also eliminates overshoot on the output voltage by controlling the current direction. The patented transient amplifier circuit ensures low supply noise and remarkable fast transient capability. It will reduce load and line related noise by filtering the output voltage. The device can provide up to 1.5A of output current, making it suitable for high power applications.

This ultra-low quiescent current and low drop-out voltage LDO linear voltage regulator is the perfect choice for high power, low noise applications. It offers a wide range of features and options to suit any design, ensuring output voltage stability and flexibility over a wide range of input voltages, with one of the best performance available in the industry.
