FM8205LA 20V N-Channel Enhancement-Mode MOSFET FM SEMI

The MAX232 device is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F voltage levels from a single 5V supply. Brand : Texas Instruments DATASHEET

The LM2575 series of regulators are monolithic integrated circuits ideally suited for easy and convenient design of a step-down switching regualtor(buck converter). All circuits of this series are capable of driving a 1A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5.0V,12V, 15V, and an adjustable output version.

The TL08xH (TL081H, TL082H, and TL084H) family of devices are the next-generation versions of the industry-standard TL08x (TL081, TL082, and TL084) devices. Brand : Texas Instruments DATASHEET

The ILX3232 is a 3.3V powered EIA/TIA-232 and V.28/V.24 communication interface with low power requirements, high data-rate capabilities. ILX3232 has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3.3vVto 5.5V supplies. The device requires only four small 0.1 µF standard external capacitors for operations from 3.3V supply. Brand : IK SEMICON DATASHEET
