The LP38859T-1.2 is a high-current linear voltage regulator capable of delivering up to 3A with a fast transient response. It operates with a dropout voltage of 240 mV at full load, making it suitable for applications requiring low input-to-output voltage differentials. The device features a precision output voltage accuracy of ¬±1.0% at 25¬8C and ¬±2.0% across a temperature range of 0¬8C to 125¬8C. It is designed with a CMOS architecture, which allows for low quiescent current consumption, typically 12 mA at 3A load current. The LP38859T-1.2 supports a wide bias supply voltage range of 3.0V to 5.5V and is stable with 10¬µF ceramic capacitors. It includes built-in over-temperature and over-current protection, enhancing reliability in various applications. The regulator is available in a TO-220 package, making it suitable for use in power supplies for desktops, notebooks, graphics cards, and other electronic devices. The programmable soft-start feature allows for controlled output voltage ramp-up, which can be beneficial in sensitive applications.
