AMS1117-1.5V SMD Fixed 12V 1.5V 800mA Dropout Regulators SOT-89
The AMS1117-1.5V is a highly efficient, fixed low dropout (LDO) linear voltage regulator specifically engineered to deliver a stable 1.5V output with a maximum continuous current capability of 800mA. Designed for modern low-voltage applications, this component utilizes advanced semiconductor technology to maintain a minimal dropout voltage of 1.40V at full load, ensuring reliable operation even when the input voltage is marginally higher than the desired output. The device is housed in a compact SOT-89 surface-mount package, making it an ideal choice for high-density printed circuit board layouts where space optimization and thermal management are critical design considerations.
Features:
- Delivers a stable 1.5V fixed positive output voltage with high precision.
- Supports a continuous output current of 800mA for reliable power delivery.
- Features an ultra-low dropout voltage of 1.40V at maximum load current.
- Incorporates on-chip thermal shutdown for enhanced device safety.
- Includes built-in over-current protection to prevent load damage.
- Exhibits excellent load regulation of 0.50% maximum across operating condition.
