STMicroelectronics LD3985G28R is a low-dropout linear voltage regulator providing a stable 2.8V output with a maximum output current of 150mA. This device features a low quiescent current of 150 µA, making it suitable for battery-powered applications. The voltage dropout is a mere 0.1V at 150mA, ensuring efficient operation even under load. Protection mechanisms include over-current and over-temperature shutdown. With a power supply rejection ratio (PSRR) ranging from 60dB to 50dB across the 1kHz to 10kHz frequency range, it effectively filters noise from the input supply. The LD3985G28R is housed in a compact TSOT-23-5 package, ideal for surface mounting in applications such as mobile devices, portable electronics, and automotive systems. It supports input voltages up to 6V and operates within a temperature range of -40°C to 125°C. The component includes an enable pin for power management.
