STMicroelectronics LD39115J18R is a low-dropout linear voltage regulator designed for efficient power management. This positive fixed output device provides a stable 1.8V with a maximum output current of 150mA. Features include a quiescent current of 50µA and a supply current of 70µA, minimizing power consumption in battery-operated applications. The device offers robust protection through over-current and over-temperature shutdown mechanisms. Its high power supply rejection ratio (PSRR) of 74dB at 1kHz ensures clean power delivery, crucial for sensitive analog circuits. The LD39115J18R operates from an input voltage range up to 5.5V. The dropout voltage is a mere 0.11V at 100mA, enabling operation from lower input voltages. Supplied in a 4-FlipChip package (4-UFBGA, FCBGA) on tape and reel, this regulator is ideal for use in portable electronics, automotive, and industrial control systems.
