The Texas Instruments LM2991S is a negative adjustable linear voltage regulator designed for high-current applications. This component offers a robust solution for generating adjustable negative output voltages from -3V down to -24V, with a maximum input voltage of -26V. It is capable of supplying a continuous output current of 1A, featuring a low dropout voltage of 1V at 1A. The LM2991S includes essential protection features such as over-temperature and short-circuit protection, enhancing system reliability. With a quiescent current of 0.7mA and a power supply rejection ratio (PSRR) of 60dB at 1kHz, it is well-suited for noise-sensitive applications. The device is available in a TO-263-6, D2PAK (5 Leads + Tab) surface-mount package, facilitating integration into compact designs. Its versatility makes it applicable in automotive and industrial sectors requiring stable negative voltage regulation.
