# TPS76201 Product Series Introduction
## Overview
The TPS76201 product series is a remarkable line of voltage regulators developed by Texas Instruments, a global leader in semiconductor solutions. These voltage regulators are designed to meet the demanding power management requirements of a wide range of electronic applications. With their high - performance features, reliability, and flexibility, the TPS76201 series has become a popular choice among engineers and designers.
## Key Features
### 1. Low Dropout Voltage
One of the standout features of the TPS76201 series is its low dropout voltage. Dropout voltage is the minimum voltage difference between the input and output voltages required for the regulator to maintain a stable output. The low dropout characteristic of the TPS76201 allows it 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 TPS76201 can still provide a stable output voltage with minimal power loss.
### 2. High Output Accuracy
The TPS76201 series offers high output voltage accuracy. This means that the actual output voltage is very close to the specified value, typically within a tight tolerance range. High output accuracy is crucial in applications where precise voltage levels are required for the proper operation of sensitive components such as microcontrollers, analog - to - digital converters (ADCs), and radio frequency (RF) circuits. For instance, in a wireless sensor node, accurate voltage regulation ensures that the RF transceiver operates at the correct frequency and power level, resulting in reliable communication.
### 3. Low Quiescent Current
Quiescent current is the current consumed by the regulator when there is no load or a very light load. The TPS76201 series 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 device is consuming minimal power, the low quiescent current of the TPS76201 ensures that the battery is not drained unnecessarily. This makes it an ideal choice for applications such as wearable devices, remote sensors, and other low - power electronics.
### 4. Thermal Shutdown and Current Limit Protection
To ensure the reliability and safety of the regulator and the connected components, the TPS76201 series is equipped with thermal shutdown and current limit protection features. Thermal shutdown protects the device from overheating by automatically shutting down the regulator when the temperature exceeds a certain threshold. This prevents damage to the internal components due to excessive heat. Current limit protection, on the other hand, limits the output current to a safe level, protecting the regulator and the load from damage caused by over - current conditions. For example, in a power - supply circuit for a motor, the current limit feature can prevent the motor from drawing too much current and damaging the regulator.
### 5. Adjustable Output Voltage
Many models in the TPS76201 series offer adjustable output voltage capabilities. This allows designers to set the output voltage according to the specific requirements of their application. By using external resistors, the output voltage can be easily adjusted within a certain range. This flexibility makes the TPS76201 suitable for a variety of applications with different voltage requirements, such as in industrial control systems where different components may require different supply voltages.
## Applications
