Frequently Asked Questions
What is the output voltage and maximum output current of the LMS8117AMP-1.8?
The LMS8117AMP-1.8 provides a fixed 1.8V output with a maximum continuous output current of 800mA, making it suitable for powering microcontrollers, FPGAs, and other moderate-load digital circuits.
What is the dropout voltage of the LMS8117AMP-1.8 and why does it matter?
The typical dropout voltage is 1.2V (maximum 1.25V), meaning the input voltage must be at least 1.2V above the 1.8V output—so a minimum of approximately 3.2V input is required. Lower dropout allows better efficiency in battery-powered applications.
What package does the LMS8117AMP-1.8 come in?
The LMS8117AMP-1.8 is available in a SOT-223 (JEDEC R-PDSO-G4) surface-mount package, which offers good thermal dissipation and is widely used in compact power management circuits on PCBs.
What are typical applications for the LMS8117AMP-1.8?
This LDO regulator is commonly used in portable electronics, IoT sensors, wearable devices, and embedded systems where a clean, stable 1.8V rail is needed for digital logic, memory, or RF components operating from a 3.3V or 5V supply.
Is the LMS8117AMP-1.8 compatible with pin-compatible LDO alternatives?
Yes, the LMS8117AMP-1.8 is pin-compatible with other AMS1117-series and LM1117-series 1.8V fixed LDO regulators in SOT-223 packages, allowing easy substitution from multiple suppliers while maintaining the same electrical and mechanical footprint.
