LT1963AEQ-3.3

The LT1963AEQ-3.3 is a low-dropout (LDO) linear voltage regulator from Analog Devices, delivering a fixed 3.3V output with up to 1.5A of current. Key features include:
- Low Dropout Voltage: As low as 340mV at full load, enhancing efficiency.
- Low Noise: Optimized for sensitive applications like RF and precision analog circuits.
- High PSRR: >60dB ripple rejection at 1kHz, reducing input noise.
- Protections: Includes current limit, thermal shutdown, and reverse-battery protection.
- Stable with Ceramic Capacitors: Requires just 10µF on the output for stability.
Packaged in a 5-lead DD-Pak (TO-263), it operates over -40°C to +125°C, making it suitable for industrial and automotive applications.
Typical uses: Powering microcontrollers, FPGAs, and noise-sensitive analog circuits where clean, stable voltage is critical.
