Texas Instruments LM340MP-5.0 3-Terminal Positive Voltage Regulator Fixed 5V 1A

Texas Instruments LM340MP-5.0 is a fixed 5V positive voltage regulator with a maximum output current of 1A, supplied in a surface-mount SOT-223-4 package. As a monolithic, three-terminal device, it is engineered for robust and reliable operation in electronic circuits.

Overview

The LM340MP-5.0 provides a fixed, stable 5V output from an input voltage range of 7.5V to 35V. It is intended primarily for local, on-card regulation, which helps to reduce noise and distribution problems commonly associated with single-point power supplies. This makes it suitable for cleaning up power rails in sensitive electronic circuits.

Beyond fixed operation, the device can be used with external components to create adjustable output voltages and currents, offering design flexibility. It forms part of the LM340 voltage regulator family, and its compact SOT-223-4 surface-mount package supports efficient use of board space in modern electronics.

Key Features

• Internal thermal overload protection safeguards the device from excessive heat.
• Internal short-circuit current limiting and output transistor safe-area protection help prevent damage under fault conditions.
• Fixed 5V output from a wide input voltage range of 7.5V to 35V.
• Maximum output current of 1A, supporting digital and analogue loads.
• Surface-mount SOT-223-4 package designed for automated assembly.

Applications

The regulator suits local power regulation on circuit boards, the cleaning up of power rails in noise-sensitive designs, and adjustable output designs built with external components. Its surface-mount package makes it appropriate for modern electronics where board space is limited.

Suitable for engineers seeking a fixed 5V positive voltage regulator with 1A output capability in a surface-mount SOT-223-4 package.
