The LT1587CT-3.6#PBF is a high-current, low dropout linear regulator from Analog Devices, providing a fixed 3.6V output. It is capable of delivering up to 3A of output current, making it suitable for a wide range of power-hungry applications. With a dropout voltage of 1.3V at full load, it can operate from a 5V rail with ease. Its excellent 72dB PSRR at 120Hz ensures clean, hum-free power for audio and precision analog circuits. The TO-220-3 package provides excellent thermal performance for high-power dissipation.
- High 3A Output Current: Suitable for powering high-current loads like audio amplifiers and industrial actuators.
- Excellent PSRR (72dB @ 120Hz): Provides superior rejection of mains-frequency noise, ideal for audio and precision instrumentation.
- Low Dropout (1.3V @ 3A): Allows efficient regulation from a standard 5V rail to 3.6V.
- Robust TO-220-3 Package: Ensures excellent heat dissipation for reliable operation under full load.
