series introduction
# TPS73701DRBR Product Series Introduction
## 1. Overview
The TPS73701DRBR 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 functionality.
## 2. Key Features
### 2.1 Low Dropout Voltage
One of the standout features of the TPS73701DRBR 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. For example, in battery - powered applications where the battery voltage gradually decreases over time, the low dropout characteristic allows the regulator to continue providing a stable output until the battery voltage drops to a very low level, thus extending the battery life.
### 2.2 High Output Voltage Accuracy
This product series offers high output voltage accuracy. It can precisely regulate the output voltage within a tight tolerance range. This is essential for applications that require a very stable power supply, such as precision analog circuits, microcontrollers, and sensors. In a sensor application, for instance, a small deviation in the power supply voltage can lead to inaccurate sensor readings. The high - accuracy output of the TPS73701DRBR ensures reliable and consistent performance of such sensitive components.
### 2.3 Low Quiescent Current
The TPS73701DRBR has a low quiescent current, which is the current consumed by the regulator when there is no load or a very light load connected to the output. In battery - operated devices, minimizing the quiescent current is crucial for reducing power consumption and extending the battery life. Even during standby or sleep modes of the device, where the load current is extremely low, the low quiescent current of the regulator helps to conserve energy.
### 2.4 Thermal Shutdown and Current Limit Protection
To ensure the reliability and safety of the regulator and the connected circuits, the TPS73701DRBR is equipped with thermal shutdown and current limit protection features. The thermal shutdown mechanism automatically turns off the regulator when its temperature exceeds a certain threshold. This protects the device from overheating, which could otherwise lead to permanent damage. The current limit protection restricts the output current to a safe level, preventing excessive current flow that could damage the regulator or other components in the circuit.
## 3. Technical Specifications
### 3.1 Input and Output Voltage Range
The TPS73701DRBR has a wide input voltage range, typically from 2.5V to 10V. This wide range allows it to be used in various power supply systems, including those powered by batteries, wall adapters, or other voltage sources. The output voltage is adjustable or fixed, depending on the specific configuration. For example, it can be set to a fixed output voltage such as 1.8V, 2.5V, 3.3V, etc., which are common voltage levels required by many electronic components.
### 3.2 Output Current Capability
It can provide a maximum output current of up to several hundred milliamperes, depending on the specific model and operating conditions. This makes it suitable for powering a wide range of loads, from small - scale integrated circuits to moderately power - hungry components.
### 3.3 Package Type
The TPS73701DRBR comes in a small - sized, surface - mount package (DRBR). The surface - mount package is ideal for modern printed circuit board (PCB) designs as it allows for easy assembly using
