Texas Instruments High-Performance Analog 5V 250mA 10V LDO Voltage Regulator IC TPS77450DGKRG4

The TPS77450DGKRG4 is a 250-mA low-dropout (LDO) voltage regulator designed for efficient power management in various applications. It features a fixed output voltage of 5.0 V and is housed in an 8-pin MSOP package. The device exhibits a typical dropout voltage of 200 mV at full load, ensuring minimal voltage loss. With a quiescent current of 92 µA during operation, it reduces to less than 1 µA in shutdown mode, making it suitable for battery-powered applications. The TPS77450 includes a power good (PG) output, which provides an active high signal to indicate when the output voltage is above 82% of its regulated value. This feature is useful for implementing power-on reset functions or low-battery indicators. The device is optimized for stability with a range of output capacitors, including low ESR ceramic and tantalum types, and offers low noise performance of 55 µVrms without the need for external filter capacitors. The TPS77450 is designed to handle fast transient responses, making it a reliable choice for systems requiring stable voltage regulation.
