The LT1117CST-3.3#PBF from Linear Technology is a positive low dropout (LDO) voltage regulator designed for efficient power management. It delivers a stable 3.3V output voltage and can supply up to 800mA of current.
Key electrical characteristics include a maximum dropout voltage of 1.2V at 800mA, ensuring efficient operation even with minimal input-to-output voltage difference. The regulator boasts excellent line and load regulation, with maximums of 0.2% and 0.4% respectively. It requires a minimum of 10µF of output capacitance for stable operation.
This device is housed in a space-saving SOT-223 surface-mount package, making it suitable for applications with limited board space. The operating temperature range is from 0°C to 125°C, accommodating various industrial and commercial environments. Its low quiescent current flows into the load, enhancing overall efficiency compared to other regulator types.
Common applications include active SCSI terminators, high-efficiency linear regulators, post-regulators for switching supplies, battery chargers, and 5V to 3.3V voltage conversion.
