The TLV73310PQDBVRQ1 is a 1.0-V fixed-output automotive low-dropout linear regulator from Texas Instruments. It belongs to the TLV733P-Q1 family of 300-mA, low-quiescent-current LDOs designed for compact automotive and embedded power-management applications.
The device operates from a 1.4 V to 5.5 V input supply and provides a regulated 1.0 V output. It can source up to 300 mA while maintaining a typical quiescent current of only 34 µA. This combination is useful for low-voltage processor, sensor and embedded-control power rails.
The TLV733P-Q1 family uses a capacitor-free architecture that provides stable operation without an input or output capacitor. This can help reduce external component count and PCB area. Ceramic capacitors may also be used when required by the system design.
The family provides approximately 1% typical output accuracy and 1.4% maximum accuracy. It also offers high power-supply rejection, reaching 50 dB at 1 kHz, which helps suppress supply noise on sensitive downstream circuits.
The TLV73310PQDBVRQ1 includes foldback overcurrent protection, thermal shutdown and active output discharge. The enable input allows controlled power sequencing and shutdown, while the output discharge function helps quickly pull the regulated rail low after the device is disabled.
The device is AEC-Q100 qualified with Grade 1 ambient operation from -40°C to +125°C. Its compact 5-pin SOT-23 package measures approximately 2.9 mm × 1.6 mm, making it suitable for space-constrained automotive electronics.
