Voltage Regulator LDO 3.3V 1A TO-220 3 Pin

The LD1117AV33 is a low drop fixed positive voltage regulator from STMicroelectronics, designed to deliver a reliable and stable output. With the ability to provide up to 1A of output current, this regulator ensures high efficiency through its NPN pass transistor architecture, making it suitable for a wide range of power management applications.

This regulator requires only a common 10μF minimum capacitor for stability, simplifying your circuit design and reducing component count. Chip trimming technology ensures a tight output voltage tolerance of within ±2% at 25°C, providing accurate and consistent performance. The device also features internal current and thermal limiting to protect against fault conditions.

Key features include a high supply voltage rejection of 80dB (typical at 25°C), ensuring clean and stable output even with noisy input supplies. The fixed output voltage is set to 3.3V, with an input voltage range from 5.3V to 10V. This through-hole TO-220 package device is easy to integrate into your PCB designs and operates over a temperature range of 0°C to 125°C.

Ideal for power management in various electronic systems, this voltage regulator delivers dependable performance for your projects.
