The LM2991S from Texas Instruments is a linear, negative, adjustable low-dropout voltage regulator designed for various power management applications. It offers an output current capability of up to 1A and an adjustable output voltage ranging from -3V to -24V. The regulator features a low quiescent current of typically 0.7 mA and a low dropout voltage of 600 mV at a 1A load.
Key electrical characteristics include a PSRR of 22 dB at 100 KHz and an accuracy of 5%. Protection features include internal short circuit current limit and thermal shutdown with hysteresis. The device operates over a temperature range of -40°C to 125°C.
Packaged in a TO-263-6, D²Pak (5 Leads + Tab), TO-263BA, the LM2991S is designed for surface mount applications. It includes an enable control feature for remote shutdown capability, making it suitable for designs requiring power sequencing or energy saving.
This regulator is a functional complement to the LM2941 series and is suitable for applications requiring a stable negative voltage supply.
