TPS7A19 Low-Dropout Linear Regulator (LDO)

Texas Instruments TPS7A19 Low-Dropout Linear Regulator (LDO) comes with a wide input voltage (V_IN) range up to 40V and is capable of sourcing high output current (I_OUT) up to 450mA. This voltage regulator is ideal for generating a low-voltage supply from wide input voltage rails. Not only does the TPS7A19 supply a well-regulated voltage rail, but the device also withstands and maintains regulation during voltage transients by acting as a simple surge protection circuit. The TPS7A19 consumes only 15µA of quiescent current (I_Q) at light loads, thereby lowering the power consumption for always-on or battery-powered applications. The TPS7A19 features integrated thermal shutdown and overcurrent protection. The Texas Instruments TPS7A19 also offers a Power Good (PG) output with a programmable delay that indicates when the output voltage is in regulation. This feature is useful for power rail sequencing functions.
