The UA78L05AILPR from Texas Instruments is a fixed 5V linear voltage regulator delivering up to 100mA of output current. Housed in a compact TO-92-3 package, it offers a dropout voltage of just 1.7V at 40mA, making it suitable for battery-operated and embedded applications. With 49dB PSRR at 120Hz, it effectively filters input ripple for clean, stable power to sensitive loads.
- Stable 5V Output: Fixed 5V regulation with ±5% accuracy ensures reliable operation for logic and analog circuits.
- Low Dropout (1.7V @ 40mA): Allows operation with minimal headroom, maximizing efficiency in battery-powered designs.
- High PSRR (49dB @ 120Hz): Effectively suppresses mains-frequency noise, ideal for audio and precision measurement.
- Thermal Protection: Internal current limiting and thermal shutdown safeguard the device and load under fault conditions.
