The TPS77433DGKR from Texas Instruments is a 250mA low-dropout (LDO) linear voltage regulator designed for efficient power management. It provides a stable 3.3V fixed output voltage with a typical dropout voltage of 200mV at 250mA. The device includes a power good (PG) status output, which is useful for monitoring power supply conditions.
Key electrical characteristics include an ultralow quiescent current of 92µA at full load, reducing power consumption. It offers a 2% output voltage tolerance over specified conditions and features fast transient response for dynamic load changes. The regulator also incorporates protection features such as over current, over temperature, and reverse polarity protection.
Packaged in an 8-pin VSSOP, the TPS77433DGKR is suitable for surface mount applications. Its operating temperature range is -40°C to 125°C, making it robust for various environmental conditions. The low noise output performance without an external filter capacitor is beneficial for noise-sensitive applications.
