Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
STMicroelectronics LD2985AM31R is a positive fixed output linear voltage regulator designed for applications requiring low quiescent current and robust performance. This device delivers a stable 3.1V output with a maximum current capability of 150mA. Featuring an Enable pin for power sequencing and a low dropout voltage of 0.575V at 150mA, it is well-suited for battery-powered systems and portable electronics. Protection features include over current and over temperature shutdown. The regulator exhibits a 45dB Power Supply Rejection Ratio (PSRR) at 1kHz, minimizing noise coupling. It is supplied in a compact SOT-23-5 package for surface mounting. This component finds application in automotive, consumer electronics, and industrial control systems.
