The L78L05ABUTR low dropout linear regulator is used in various power management designs because it is reliable and efficient. This article will introduce its features, application scenarios, and advantages in power management.

Introduction Of STMicroelectronics L78L05ABUTR

The L78L05ABUTR is a three-terminal positive voltage regulator with built-in current limiting and thermal shutdown, making it super durable. With enough heat dissipation, it can provide up to 100mA of output current. This regulator is designed for fixed voltage regulation in a variety of applications, including on-board or local regulation to reduce noise and address issues related to single-point regulation. Additionally, it can work with power pass elements to create high-current voltage regulators. It's a more efficient alternative to Zener diode/resistor combinations, offering lower quiescent current and reduced noise.

L78L05ABUTR Features

• Thermal Overload Protection：The voltage regulator shuts down when it gets too hot, which prevents damage and extends the life of the components.
• Short Circuit Protection：Short-circuit protection keeps the device and connected circuits safe from damage caused by short circuits.
• No External Components Required：The L78L05ABUTR can be used without any other parts, making it easier to design circuits and reducing the overall cost.
• Choice of ±4% (A) or ±8% (C)：The device has different output voltage regulation tolerances depending on the version.
