Frequently Asked Questions
What is the output voltage and maximum output current of the LM1117IDT-3.3/NOPB?
The LM1117IDT-3.3/NOPB provides a fixed 3.3V output with a maximum continuous output current of 800mA. The output accuracy is ±1% under typical line and load conditions, making it suitable for precision digital and analog circuits.
What input voltage range does the LM1117IDT-3.3/NOPB support?
The device supports an input voltage range from 4.75V to 15V, with an absolute maximum of 20V. The typical dropout voltage is 1.2V (maximum 1.4V), so a minimum input of approximately 4.5V is needed to maintain 3.3V regulation at full load.
What are typical applications for the LM1117IDT-3.3/NOPB?
Common applications include 3.3V power supply rails for microcontrollers (e.g., STM32, Arduino), FPGAs, Wi-Fi/Bluetooth modules, and sensor boards. It is also used in USB-powered devices, IoT nodes, and portable instruments that require a stable low-dropout regulated supply.
What package does the LM1117IDT-3.3/NOPB use, and is it RoHS compliant?
The LM1117IDT-3.3/NOPB comes in a SOT-223 (3-pin, TO-XXX/DPAK family) surface-mount package, which provides good thermal performance on a PCB. The part is fully RoHS compliant and REACH compliant, making it suitable for lead-free manufacturing environments.
Are there pin-compatible alternatives or substitutes for the LM1117IDT-3.3/NOPB?
Yes, pin-compatible alternatives in the SOT-223 package include the AMS1117-3.3, AP1117-33, and LD1117S33TR from various manufacturers. These parts share the same pinout and similar electrical characteristics (800mA, 3.3V fixed), allowing drop-in replacement in most designs.
