# TPS76950QDBVRQ1 Product Series Introduction
## 1. Overview
The TPS76950QDBVRQ1 is a highly reliable and efficient voltage regulator product series specifically designed to meet the demanding requirements of automotive and other high - reliability applications. This series is part of Texas Instruments' extensive portfolio of power management solutions, offering stable and precise voltage regulation in a compact and cost - effective package.
## 2. Key Features
### 2.1 Automotive - Grade Quality
- **AEC - Q100 Qualified**: The TPS76950QDBVRQ1 is AEC - Q100 qualified, which means it has undergone rigorous testing to meet the strict automotive industry standards for reliability, performance, and quality. This qualification ensures that the product can operate reliably in the harsh automotive environment, including wide temperature ranges, high humidity, and electrical noise.
- **ESD Protection**: It provides built - in electrostatic discharge (ESD) protection, safeguarding the device from potential damage caused by static electricity during handling and operation. This feature is crucial in automotive applications where ESD events can occur frequently.
### 2.2 Low Dropout Voltage
- **Efficient Power Conversion**: The device has a low dropout voltage, which allows it to maintain a stable output voltage even when the input voltage is only slightly higher than the output voltage. This low dropout characteristic results in high - efficiency power conversion, reducing power dissipation and heat generation. For example, in battery - powered applications, it helps to extend the battery life by minimizing power losses.
### 2.3 Adjustable Output Voltage
- **Flexibility in Design**: The TPS76950QDBVRQ1 offers adjustable output voltage capabilities. Designers can easily set the output voltage to the desired level within a specified range, providing flexibility to meet the power requirements of different loads. This feature is particularly useful in applications where multiple voltage levels are needed, such as in automotive infotainment systems and advanced driver - assistance systems (ADAS).
### 2.4 Low Quiescent Current
- **Power Savings in Standby Mode**: The product has a low quiescent current, which is the current consumed by the regulator when there is no load or in standby mode. This low quiescent current helps to conserve power, making it suitable for applications that require long - term battery operation or low - power standby functionality.
### 2.5 Thermal Shutdown and Current Limit Protection
- **Enhanced Safety**: It is equipped with thermal shutdown and current limit protection features. The thermal shutdown protection automatically turns off the device when the temperature exceeds a certain threshold, preventing overheating and potential damage. The current limit protection restricts the output current to a safe level, protecting the device and the connected load from over - current conditions.
## 3. Applications
### 3.1 Automotive Electronics
- **Infotainment Systems**: In automotive infotainment systems, the TPS76950QDBVRQ1 can provide stable power to various components such as touchscreens, audio amplifiers, and microcontrollers. Its low dropout voltage and adjustable output voltage features ensure reliable operation and efficient power management.
- **ADAS**: Advanced driver - assistance systems rely on accurate and stable power supplies. The TPS76950QDBVRQ1 can be used to power sensors, cameras, and processing units in ADAS, providing the necessary power stability for these critical safety - related applications.
- **Engine Control Units (ECUs)**: ECUs require precise voltage regulation to ensure proper engine performance. The automotive - grade quality and protection features of the TPS76950QDBVRQ1 make it a suitable choice for powering ECUs in automotive engines.
