Texas Instruments Adjustable Linear Voltage Regulator 500mA SOT-223

Texas Instruments Adjustable Linear Voltage Regulator 500mA is a 3-terminal adjustable positive linear voltage regulator capable of supplying more than 500mA over an output voltage range of 1.25V to 37V.

Overview

The regulator requires only two external resistors to set the desired output level, offering flexibility for a wide range of electronic applications. It is designed to provide a stable power supply, with line and load regulation that supports consistent performance when input voltage or load conditions fluctuate.

Key Features

• Internal short-circuit current limiting
• Thermal-overload protection
• Safe-operating-area compensation
• Protection remains functional if the ADJUST terminal is disconnected
• Floating regulator with no device ground terminal, directing quiescent current to the load
• Constructed as a green product, free from antimony and bromine (Sb/Br)

Applications

The regulator can be used to create high-voltage regulated outputs, provided the maximum input-to-output differential does not exceed 40V at any time. It can also be configured as a precise floating current source controlled by a single external resistor.
