The Texas Instruments TPS77901DGKR is a versatile 250-mA low-dropout (LDO) linear voltage regulator designed for various power management applications. It provides an adjustable output voltage ranging from 1.5 V to 5.5 V, with fixed output options available at 1.8 V, 2.5 V, and 3 V. The device operates with an input voltage range of 2.7 V to 10 V.
Key electrical characteristics include a typical dropout voltage of 200 mV at 250 mA and an ultralow quiescent current of 92 µA at full load, dropping to 1 µA when disabled. It also features low noise performance (55 µVrms) without a bypass capacitor and a Power Supply Rejection Ratio (PSRR) of 24 dB at 100 kHz. Protection features include over current, over temperature, and reverse polarity.
This regulator is housed in an 8-pin VSSOP package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C. The TPS77901DGKR includes control features such as Enable and Reset, making it suitable for designs requiring power sequencing or monitoring.
