series introduction

# TPS76901HDBVT Product Series Introduction

## 1. Overview
The TPS76901HDBVT belongs to a high - performance voltage regulator product series designed and manufactured by Texas Instruments. These voltage regulators are engineered to provide stable and reliable power supply solutions for a wide range of electronic applications, ensuring the proper functioning of various components within a system.

## 2. Key Features

### 2.1 Low Dropout Voltage
One of the standout features of the TPS76901HDBVT is its low dropout voltage. Dropout voltage is the minimum difference between the input voltage and the output voltage required for the regulator to maintain a stable output. A low dropout voltage allows the regulator to operate efficiently even when the input voltage is only slightly higher than the desired output voltage. This is particularly useful in battery - powered applications where the battery voltage decreases over time. For example, in a portable device running on a single - cell lithium - ion battery, as the battery discharges, the TPS76901HDBVT can still provide a stable output voltage with minimal power loss.

### 2.2 High Output Voltage Accuracy
The series offers high output voltage accuracy, typically within a tight tolerance range. This precision is crucial for applications that require a specific and stable voltage level, such as in precision analog circuits, microcontrollers, and digital signal processors. The accurate output voltage ensures that these components operate within their specified voltage ranges, reducing the risk of malfunctions and improving overall system performance.

### 2.3 Low Quiescent Current
Quiescent current is the current consumed by the regulator when there is no load or a very light load connected to the output. The TPS76901HDBVT has a low quiescent current, which is beneficial for battery - powered devices as it helps to extend the battery life. In standby or sleep modes, where the load current is minimal, the low quiescent current ensures that the battery is not drained unnecessarily.

### 2.4 Thermal Shutdown and Current Limiting
To protect the regulator and the connected components from damage, the TPS76901HDBVT is equipped with thermal shutdown and current - limiting features. Thermal shutdown automatically turns off the regulator when the temperature exceeds a safe operating limit, preventing overheating and potential damage to the device. Current limiting restricts the output current to a safe level, protecting the regulator from short - circuits and over - current conditions.

## 3. Electrical Specifications

### 3.1 Input and Output Voltage Range
The input voltage range of the TPS76901HDBVT is designed to accommodate a variety of power sources. It can typically accept input voltages within a certain range, for example, from 2.5V to 6V. The output voltage is fixed at a specific value, such as 1.8V, 2.5V, or 3.3V, depending on the specific model within the series. This flexibility in input voltage and the availability of different output voltage options make it suitable for a wide range of applications.

### 3.2 Output Current Capability
The series can provide a certain amount of output current, which is an important parameter for determining the number and type of components that can be powered by the regulator. For the TPS76901HDBVT, it can typically supply output currents in the range of several hundred milliamperes, making it suitable for powering small to medium - sized loads such as sensors, microcontrollers, and small integrated circuits.

### 3.3 Noise Performance
Low output noise is essential for applications that are sensitive to electrical noise, such as audio circuits and high - precision analog sensors. The TPS76901HDBVT is designed to have low output
