LM2940SX-10

IC REG LIN 10V 1A DDPAK/TO263-3

Manufacturer: Texas Instruments

Categories: Linear, Low Drop Out (LDO) Regulators

Quality Control: Learn More

Texas Instruments LM2940SX-10 is a positive fixed 10V linear voltage regulator IC with a 1A output current capability. This TO-263 (DDPAK-3) surface mount device offers a low dropout voltage of 1V at 1A, ensuring efficient operation. Key protection features include over current, over temperature, reverse polarity, and short circuit protection. The regulator operates across a temperature range of -40°C to 125°C and features a high power supply rejection ratio (PSRR) of 63dB at 120Hz. Suitable for automotive, industrial, and consumer electronics applications, this component is supplied on a Tape & Reel (TR). The input voltage range extends up to 26V, with a quiescent current of 10 mA and a supply current of 15 mA (Max).

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
