series introduction
# CPC1117NTR Product Series Introduction
## 1. Overview
The CPC1117NTR product series is a highly reliable and efficient line of low - dropout (LDO) voltage regulators. These regulators are designed to provide a stable output voltage in a wide range of applications, ensuring the proper functioning of electronic devices by delivering a consistent power supply. With their compact design and excellent performance characteristics, they have become a popular choice among engineers and designers in various industries.
## 2. Key Features
### 2.1 Low Dropout Voltage
One of the most significant features of the CPC1117NTR series 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. The low dropout nature of these regulators allows them to 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 gradually decreases over time. For example, in a portable device powered by a single lithium - ion battery, the CPC1117NTR can continue to provide a stable output voltage as the battery voltage drops, extending the battery life and ensuring consistent device performance.
### 2.2 High Output Current Capability
The CPC1117NTR series is capable of delivering a relatively high output current. This makes it suitable for powering a wide range of load devices, from small - scale integrated circuits to more power - hungry components. The high - current output capability ensures that the regulator can meet the power demands of various applications without experiencing significant voltage drops or overheating. For instance, it can power multiple microcontrollers, sensors, and other peripherals in a complex embedded system, providing a reliable power source for the entire system.
### 2.3 Excellent Line and Load Regulation
Line regulation refers to the ability of the regulator to maintain a constant output voltage despite changes in the input voltage. Load regulation, on the other hand, is the regulator's ability to keep the output voltage stable when the load current changes. The CPC1117NTR series offers excellent line and load regulation, ensuring that the output voltage remains within a very narrow tolerance range under different operating conditions. This is crucial for applications that require precise voltage levels, such as analog circuits and sensitive electronic components.
### 2.4 Thermal Over - Protection
To prevent damage due to excessive heat, the CPC1117NTR series is equipped with thermal over - protection. When the temperature of the regulator exceeds a certain threshold, the thermal protection circuit kicks in and reduces the output current or shuts down the regulator temporarily. This feature helps to ensure the long - term reliability and safety of the regulator, especially in high - power or high - temperature environments.
### 2.5 Short - Circuit Protection
Another important safety feature of the CPC1117NTR series is short - circuit protection. In the event of a short - circuit at the output, the regulator automatically limits the output current to a safe level, preventing damage to the regulator and other components in the circuit. This protection mechanism enhances the overall robustness of the power supply system and reduces the risk of component failure.
## 3. Technical Specifications
