Description
The ST1S14PHR is a robust, monolithic step-down voltage regulator capable of delivering up to 3A of continuous output current. Designed for high-performance power management, it features an exposed pad HSOP8 package that provides excellent thermal dissipation, allowing it to handle high current loads efficiently. With an input voltage range of up to 48V, it is a versatile choice for a wide variety of industrial and consumer power applications.
This regulator uses an internal N-channel DMOS transistor to keep your circuit compact by reducing the need for large external components. It also includes smart safety features like power-good monitoring, constant current short-circuit protection, and thermal shutdown, ensuring your electronic projects remain safe and stable under load.
Key Features
- High Current Capacity: Delivers up to 3A to your load, making it perfect for power-hungry components.
- Wide Input Range: Handles input voltages from 5.5V to 48V, giving you flexibility for different power sources.
- Power Good Output: Features an open collector output to confirm when your regulated voltage is stable and ready.
- Safety Protections: Built-in thermal shutdown and pulse-by-pulse current limiting protect your circuit from short circuits and overstress.
