LDO basics video series

This LDO basics video series will cover topics including dropout voltage, current limit, power supply rejection ration (PSRR), noise, thermals, and many more. The video series will also introduce key performance features, explain impact in power management, give example applications, and answer commonly asked questions. 

1. Introduction to LDO basic series

Introductory video highlighting the topics reviewed in the LDO Basics Training Series. We will go over what LDO's are and analyze the important characteristics of LDO's. This series will also explain the impact of LDO's in power management and give examples of LDO applications. For more information go to http://ti.com/ldo. Stop by the "Support & training" tab for more LDO videos and visit the E2E forum to read what our experts have to say about LDO's.

2. Dropout voltage

This video will go over what an LDO is and discuss the importance of dropout voltage in an LDO. An application will demonstrate the importance of dropout voltage when designing as dropout voltage can affect the desired output of an LDO. The designer must keep the input voltage and dropout voltage in mind when using an LDO. Furthermore, PMOS and NMOS architectures used in LDO's will be covered as this has the most impact to the dropout voltage. The video will also show other variables such as pass element size, temperature, output current, temperature, and output accuracy that all can affect dropout voltage.

3. Capacitor vs. capacitance

In order for an LDO to operate normally, you need an output capacitor. A common issue when designing LDOs into an application is selecting the correct output capacitor. In this video, Wilson will explore the different considerations when selecting an output capacitor and how it may affect your LDO.

4. Thermals

You can further improve your application’s performance when you consider thermals. An LDO’s nature is to regulate a voltage by turning excess power into heat, making this integrated circuit a good fit for low-power or small VIN-to-VOUT differential applications. With this in mind, choosing the right LDO with the right package is crucial to maximizing an application’s performance. Watch this video to understand how the smallest available package isn’t always the best match for the desired application.

5. Quiescent current

How aggravating is it to pick up an electronic device that you’ve barely used, only to find that the battery is nearly or completely dead? If your device was just on standby or asleep, this may have happened because of a small but crucial specification: quiescent current. In this video, Wilson explores how LDOs are a simple solution to help boost the run time of any battery-driven device - for a few more seconds, minutes, hours or even days.

6. Power Supply Rejection Ratio (PSRR)

This video will go over what Power Supply Rejection Ratio (PSRR) is and will explore an application in which one can calculate the PSRR. The PSRR calculations follows a formula in which one can find the values to the equation either from the electrical characteristics or from the PSRR versus frequency plot provided in the data sheet. The video also highlights the importance of output capacitors and the difference between the input voltage and output voltage as these parameters can affect the PSRR value. Other factors than can influence PSRR value also include noise reduction capacitor, feed-forward capacitor, and PCB layout.
