Categories: Linear, Low Drop Out (LDO) Regulators

Quality Control: Learn More

STMicroelectronics LD2985AM47R is a fixed 4.7V positive linear voltage regulator designed for applications requiring precise voltage regulation and low quiescent current. This device delivers a stable 150mA output current with a low dropout voltage of 0.575V at 150mA. Key features include an enable pin for power sequencing and robust protection against overcurrent and overtemperature conditions. The LD2985AM47R boasts a high Power Supply Rejection Ratio (PSRR) of 45dB at 1kHz, making it suitable for noise-sensitive applications. It operates within an input voltage range of up to 16V and is packaged in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount configuration, ideal for space-constrained designs. This component finds application in automotive, industrial, and consumer electronics where reliable power management is critical. The device is supplied on tape and reel.

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.
