TPS79733QDCKRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS79733QDCKRQ1 is an automotive-qualified, low-dropout (LDO) linear voltage regulator designed for battery-powered applications. It provides a stable 3.3V output at up to 10mA with an ultralow quiescent current of 1.2µA. This device is stable with any output capacitor greater than 0.47µF, minimizing board space requirements.

 

The TPS79733QDCKRQ1 operates over a temperature range of -40°C to 125°C and features protection mechanisms including over-current and reverse polarity protection. It includes an integrated open-drain active-high power good (PG) output, which is beneficial for system monitoring.

 

Packaged in a 5-pin SC-70-5 (SOT-323) surface-mount package, this LDO regulator is suitable for space-constrained designs. Its low dropout voltage, typically 105mV at 10mA, and ultralow power consumption contribute to extended system battery life, making it ideal for microcontroller-based and battery-operated devices.
