LD1117S18TR/ROHS Description

Short technical summary and product information.

The LD1117S18TR/ROHS is a linear voltage regulator manufactured by ST, offering a fixed output voltage of 1.1V. This device can supply a maximum output current of 0.3A (300mA), making it suitable for various low-power applications requiring a stable voltage source. It operates efficiently across an input voltage range from 1.7V to 5.25V.

Key electrical characteristics include a typical quiescent current of 35µA and a maximum dropout voltage of 0.7V at 300mA. The regulator also features a typical PSRR (Power Supply Rejection Ratio) of 75dB at 1kHz, ensuring good ripple rejection. With a voltage regulation accuracy of 1%, it provides reliable performance for sensitive electronic circuits.

Designed for operation in a temperature range from -40°C to 85°C, the LD1117S18TR/ROHS can dissipate up to 400mW of power. Its thermal resistance from junction to ambient is typically 237°C/W, and from junction to case is 96°C/W, which are important considerations for thermal management in circuit design.
