The L78MR05-FA-E linear voltage regulator is a three-terminal device designed to provide adjustable output voltage. It can adjust the output voltage between 1.2 V and 5.5 V and has a maximum output current of 100 mA. This regulator is designed to be used in a wide variety of applications, such as computing and consumer electronics.
Overview
The L78MR05-FA-E is a voltage regulator that offers excellent performance and cost-effectiveness. It uses a low dropout (LDO) design, which means that the input and output voltages can be as close together as 0.2V. This helps to protect sensitive components from damage due to voltage drops. The device also has an onboard voltage reference, which ensures that the output voltage is always stable and predictable. The regulator also includes built-in current limiting, thermal protection, and short-circuit protection. Additionally, it has an over-temperature shutdown feature to protect the device from heat stress.The L78MR05-FA-E features an adjustable output voltage, which can be set between 1.2 V and 5.5 V. This can be adjusted via the onboard feedback potentiometer. The device also has a fast transient response, which helps to ensure that the output voltage always meets the system’s needs.Features and benefits
The L78MR05-FA-E offers a number of benefits for applications such as computing and consumer electronics. Some of the main features and benefits include:- Low dropout design ensures that the input and output voltages are as close together as possible, which helps to protect sensitive components from damage.
- Adjustable output voltage range of 1.2 V to 5.5 V.
- Onboard voltage reference ensures that the output voltage is always stable and predictable.
- Built-in current limiting, thermal protection, and short-circuit protection.
- Over-temperature shutdown feature helps to protect the device from heat stress.
- Fast transient response helps to ensure that the output voltage meets system needs.
Applications
The L78MR05-FA-E is designed to be used across a wide variety of applications. It is ideal for computing and consumer electronics applications that require a reliable and cost-effective voltage regulator. It is also perfect for low voltage analog and digital circuit applications.Working principle
The L78MR05-FA-E works by using a linear voltage regulator design. In this design, the regulator takes voltage from an input source, such as a battery, and uses it to control the output voltage. The regulator works by amplifying the difference between the input and output voltages. The regulated output voltage is then determined by the feedback resistor and voltage reference.The regulator also includes a current limiter to protect the device from excessive current flows. If a short circuit occurs or the current limit is exceeded, the device shuts down and the load is no longer powered. The current limit is designed to be adjustable to match the needs of the system.The L78MR05-FA-E is also equipped with thermal protection and over-temperature shutdown features to protect the device from heat stress. These features ensure that the device does not get too hot and does not become damaged.Overall, the L78MR05-FA-E is a highly reliable, efficient, and cost-effective linear voltage regulator. It is perfect for use in a variety of applications, such as computing and consumer electronics. Its adjustable output voltage, current limiting, and thermal protection features help to ensure that the device is always working as it should be.The specific data is subject to PDF, and the above content is for reference
