NCV8690MN33T2G

Product Overview

The NCV8690MN33T2G from onsemi is a single positive fixed-output linear voltage regulator that provides a 3.3 V output at up to 1 A. It uses a 6-DFN (3x3) surface-mount package with an exposed pad, supporting compact board layouts. The device has a maximum input voltage of 6 V and a maximum dropout voltage of 0.25 V at 1 A, with a quiescent current of 200 µA and a maximum supply current of 240 µA. It includes over-temperature and short-circuit protection and is rated for an operating temperature range of -40°C to 125°C. The regulator is automotive grade and carries AEC-Q100 qualification.

Key Features

• Fixed positive 3.3 V output with 1 A output current
• Maximum input voltage of 6 V and maximum dropout voltage of 0.25 V at 1 A
• Quiescent current of 200 µA and maximum supply current of 240 µA
• Over-temperature and short-circuit protection
• Operating temperature range of -40°C to 125°C
• Automotive grade with AEC-Q100 qualification
• Surface-mount 6-VDFN exposed pad package, 6-DFN (3x3)

Applications

• Fixed 3.3 V rail for digital logic or sensor subsystems powered from an input not exceeding 6 V
• Automotive electronic modules requiring an AEC-Q100 qualified linear regulator
• 3.3 V supply generation in compact board layouts using a 6-DFN (3x3) surface-mount package

Design & Procurement Notes

Designers should verify that the input voltage remains within the 6 V maximum and that thermal dissipation is adequate at the selected output current, particularly near the 1 A rating where dropout is specified at 0.25 V. The 6-VDFN exposed pad package requires surface-mount layout and thermal relief appropriate for the expected ambient range of -40°C to 125°C. For applications requiring AEC-Q100 qualification, the automotive grade designation should be confirmed against the final system requirements.
