series introduction
# TPS72525DCQR Product Series Introduction
## 1. Overview
The TPS72525DCQR is a highly reliable and efficient voltage regulator product series offered by Texas Instruments. This series is specifically designed to meet the demanding power management requirements of various electronic applications, providing stable and precise voltage regulation in a compact and cost - effective package.
## 2. Key Features
### 2.1 Low Dropout Voltage
One of the standout features of the TPS72525DCQR 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. With a low dropout voltage, this regulator can operate effectively 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 powered by a single - cell lithium - ion battery, as the battery discharges, the TPS72525DCQR can still provide a stable output voltage until the battery voltage drops to a very low level.
### 2.2 High Output Voltage Accuracy
The TPS72525DCQR offers high output voltage accuracy. It can maintain the output voltage within a tight tolerance, typically ±2% over a wide range of operating conditions. This high accuracy is crucial in applications where precise voltage levels are required for the proper functioning of sensitive components such as microcontrollers, sensors, and analog circuits. For instance, in a sensor - based monitoring system, accurate voltage supply ensures that the sensors can provide reliable and consistent data.
### 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 TPS72525DCQR has a low quiescent current, which helps to extend the battery life in battery - powered applications. In standby or sleep modes of electronic devices, where power consumption needs to be minimized, the low quiescent current of this regulator ensures that the battery drains at a slower rate.
### 2.4 Thermal Shutdown and Current Limiting
To protect the device and the connected components from damage, the TPS72525DCQR 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 load from excessive current flow, which could occur due to short - circuits or other faults.
## 3. Electrical Specifications
### 3.1 Input Voltage Range
The TPS72525DCQR has a wide input voltage range, typically from 2.7V to 5.5V. This wide range allows it to be used with various power sources, including single - cell and multi - cell batteries, as well as regulated power supplies.
### 3.2 Output Voltage
The output voltage of the TPS72525DCQR is fixed at 2.5V. This specific output voltage is commonly used in many electronic circuits, such as powering low - voltage microcontrollers, memory chips, and other digital components.
### 3.3 Output Current
It can provide a maximum output current of up to 150mA. This makes it suitable for a wide range of low - to medium - power applications, including portable devices, IoT sensors, and small - scale embedded systems.
