TLV76718DGNR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TLV76718DGNR is a fixed-output linear voltage regulator from the Texas Instruments TLV767 family, housed in an 8-pin HVSSOP package. It provides a nominal output voltage of 1.8 V with a maximum load current capability of 1 A and supports input voltages ranging from 2.5 V to 16 V. The device features a typical quiescent current of 50 µA and achieves high power-supply rejection ratios of 70 dB at 1 kHz and 46 dB at 1 MHz. It includes internal protections such as foldback current limiting and thermal shutdown, ensuring stable operation across a temperature range of –40°C to +125°C.

• Delivers precise 1% output accuracy over varying load conditions and temperatures.
• Incorporates internal soft-start functionality to minimize inrush current during startup.
• Features foldback current limiting and thermal protection for robust fault handling.
• Operates stably with small ceramic capacitors, requiring only 1-µF input and output capacitance.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Motion detectors including PIR and uWave sensors
• Motor drives and control boards
• Printers and PC peripherals

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix 'DGNR' corresponds to the 8-pin HVSSOP package and tape-and-reel packaging configuration. Confirm that the fixed 1.8 V output variant matches the design requirements, as the broader TLV767 series offers adjustable versions and other fixed voltage options. Ensure component authenticity through authorized distribution channels.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a wide input voltage range up to 16 V is required alongside high current delivery. The low quiescent current makes it suitable for standby-sensitive designs. Verify that the 8-pin HVSSOP footprint fits the PCB layout constraints and that the thermal performance meets the application's dissipation needs under maximum load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the TLV767 series of precision linear regulators designed for applications demanding high current and low noise. The series distinguishes itself by offering significantly lower quiescent current compared to traditional wide-input regulators. Available packages include WSON, HVSSOP, and SOT-23, providing flexibility for various board space requirements.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Other members of the TLV767 family, such as TLV767xxDBVR or TLV767xxDRV, offer alternative package styles or adjustable output configurations. Cross-reference pinouts and thermal characteristics carefully when substituting, as package dimensions and thermal resistance values differ between WSON, HVSSOP, and SOT-23 variants.
