LM2991T Information

Description

The LM2991T is a low dropout (LDO) voltage regulator from Texas Instruments. It's an integrated circuit that provides a regulated voltage output with a wide input voltage range of 4V to 60V. The device has an adjustable output voltage, high output current capability up to 1A, and overload protection with thermal shutdown for added safety and reliability. The LM2991T is commonly used in applications such as automotive systems, industrial power supplies, battery chargers, and more, where a regulated power supply with high efficiency and low dropout voltage is required. The device's small form factor and 16-pin TO-220 package make it suitable for space-constrained designs.

Features

According to the product information, the features of the LM2991T are:

  • Integrated low dropout voltage regulator
  • Wide input voltage range: 4V to 60V
  • Adjustable output voltage
  • Low dropout voltage: 0.5V at 1A
  • Overload protection with thermal shutdown
  • High output current capability: up to 1A

These features make the LM2991T suitable for applications such as automotive systems, industrial power supplies, battery chargers, and other applications requiring a regulated power supply with high efficiency and low dropout voltage.

Package

According to the product information, the package type of LM2991T is a TO-220-5 package with 5 pins.

Pinout
