The TPS74515PQWDRVRQ1 is a 1.5-V fixed-output automotive low-dropout linear regulator from Texas Instruments. It is part of the TPS745-Q1 family of 500-mA LDO regulators featuring low quiescent current, high power-supply rejection and Power-Good functionality.
The device operates from a 1.5 V to 6.0 V input supply and provides a regulated 1.5 V output with up to 500 mA of load current. Its typical quiescent current is only 25 µA, making it suitable for automotive electronics where power efficiency and standby consumption are important.
The TPS745-Q1 architecture provides high PSRR, reaching 45 dB at 100 kHz, while maintaining low dropout operation. The family specifies a maximum dropout voltage of 160 mV at 500 mA under the 3.3-V output test condition. The actual dropout voltage of a fixed-output variant depends on the operating conditions.
A Power-Good output monitors the regulated output and can be used with the enable input for sequencing multiple power supplies. The device also integrates active output discharge, foldback current limiting, thermal shutdown and undervoltage lockout.
The TPS74515PQWDRVRQ1 is stable with a 1-µF or larger effective capacitor. Its 2 mm × 2 mm wettable-flank WSON package helps minimize PCB area while supporting optical inspection of solder joints in automotive manufacturing.
As an AEC-Q100 qualified Grade 1 device, the TPS74515PQWDRVRQ1 is designed for automotive power-management applications including processor rails, sensor modules, communication electronics and other low-voltage subsystems.
