The LM2990SX-15 is a negative low dropout regulator from Texas Instruments, designed to provide a fixed output voltage of -15 V. It operates with an input voltage range from -26 V to -6 V and can deliver output currents exceeding 1 A. The device features a typical dropout voltage of 0.6 V at 1 A load current, ensuring efficient operation in low-voltage applications. It maintains an output accuracy of ¬±5% across its entire operating range and has a low quiescent current of approximately 1 mA under typical conditions. The LM2990SX-15 includes internal short-circuit current limiting and thermal shutdown with hysteresis for enhanced reliability. It is suitable for applications such as post-switcher regulation, local on-card regulation, and battery-operated equipment. The regulator is available in a 3-pin DDPAK/TO-263 package and is rated for operation over a temperature range of -40¬8C to 125¬8C.
