Key Features
- 1 A output current with 0.9 V nominal dropout on a 16 V-rated input, supporting high-side bus regulation in industrial systems
- Wide -40°C to 125°C operating range for reliable performance in harsh industrial and automotive environments
- Compact 8-pin HVSSOP package with exposed thermal pad for improved heat dissipation at full 1 A load
Applications
The TLV76728DGNR is well suited for post-regulation of industrial 12 V or 15 V bus rails down to a stable 2.8 V supply for sensors, DACs, and analog front-ends. Its 1 A current capability and 125°C rated operation make it appropriate for automotive infotainment modules, motor drive control boards, and factory automation equipment. The fixed 2.8 V output and HVSSOP package simplify PCB design where a compact, high-voltage-capable LDO is required.

Frequently Asked Questions
How much current can TLV76728DGNR supply and what dropout voltage should designers expect?
TLV76728DGNR delivers up to 1 A output current. The nominal dropout voltage is 0.9 V, with a maximum of 1.3 V at full load. This means the device needs at least a 4.1 V input to maintain the regulated 2.8 V output under worst-case conditions, making it practical for 5 V, 12 V, and 15 V input rails found in industrial power architectures.
What makes TLV76728DGNR suitable for automotive or industrial temperature environments?
TLV76728DGNR is rated for an operating temperature range of -40°C to 125°C, covering the full automotive and industrial grade requirements. The 8-pin HVSSOP package includes an exposed thermal pad that helps dissipate heat when the device supplies the full 1 A at larger input-to-output differentials, maintaining reliable operation across the wide temperature range without external heatsinking in most cases.
Can TLV76728DGNR regulate directly from a 12 V automotive battery rail?
Yes. TLV76728DGNR accepts inputs up to 16 V continuous and an absolute maximum of 18 V, so a nominal 12 V automotive rail with transients up to 16 V is well within its safe operating range. It produces a fixed 2.8 V output at up to 1 A, making it a straightforward solution for powering 2.8 V analog sensors, RF modules, or microcontroller I/O domains from the vehicle supply.
How does TLV76728DGNR compare to an adjustable LDO for a fixed 2.8 V rail application?
A fixed-output variant like TLV76728DGNR eliminates the two external resistors needed by an adjustable LDO to set the output voltage, reducing component count and the risk of output voltage error due to resistor tolerance. The fixed 2.8 V configuration also avoids soft-start overshoot that can occur with adjustable designs, providing a cleaner power-on ramp for precision analog and mixed-signal loads sensitive to supply transients.
