series introduction
# TPS73201DBVR Product Series Introduction
## 1. Overview
The TPS73201DBVR belongs to a high - performance voltage regulator product series offered by Texas Instruments. Voltage regulators are crucial components in electronic circuits as they ensure a stable and consistent voltage supply to various electronic devices, protecting them from voltage fluctuations and ensuring proper operation.
## 2. Key Features
### 2.1 Low Dropout Voltage
One of the standout features of the TPS73201DBVR 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 means that the regulator can 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 TPS73201DBVR can still provide a stable output voltage with a small input - output voltage differential.
### 2.2 High Output Voltage Accuracy
The TPS73201DBVR offers high output voltage accuracy. It can precisely regulate the output voltage within a tight tolerance range. This accuracy is essential for applications that require a specific and stable voltage, such as in precision analog circuits, microcontrollers, and sensors. For instance, in a sensor system, a stable and accurate voltage supply is necessary to ensure the correct operation and accurate measurement of the sensor, and the TPS73201DBVR can meet this requirement.
### 2.3 Low Quiescent Current
Quiescent current is the current consumed by the regulator when there is no load or a very light load. The TPS73201DBVR has a low quiescent current, which is beneficial for power - sensitive applications. In battery - powered devices, minimizing the quiescent current helps to extend the battery life. For example, in a wearable device that is often in standby mode, the low quiescent current of the TPS73201DBVR ensures that the battery drains slowly during these periods.
### 2.4 Thermal Shutdown and Current Limiting
To protect the device from damage, the TPS73201DBVR is equipped with thermal shutdown and current - limiting features. Thermal shutdown automatically turns off the regulator when the temperature exceeds a certain threshold, preventing overheating and potential damage to the device. Current limiting restricts the output current to a safe level, protecting the regulator and the connected load from excessive current, which could be caused by a short - circuit or other faults.
## 3. Package and Pin Configuration
The TPS73201DBVR comes in a small - outline package (SOP), specifically the DBV package. This package is compact, which is suitable for space - constrained applications such as mobile devices, IoT modules, and small - form - factor consumer electronics. The pin configuration of the TPS73201DBVR is designed for easy integration into circuit boards. It typically has pins for input voltage, output voltage, ground, and an enable pin. The enable pin allows the user to turn the regulator on or off, which can be useful for power management in systems where power needs to be conserved.
## 4. Applications
### 4.1 Portable Electronic Devices
In portable devices such as smartphones, tablets, and smartwatches, the TPS73201DBVR can be used to regulate the voltage supplied to various components. For example, it can provide a stable voltage to the microprocessor, memory chips, and display drivers. Its low dropout voltage and low quiescent current make it ideal for these battery - powered applications
