What are the key features of LM22674QMRE-5.0/NOPB?
- 500 mA continuous output current with 4.5 V to 42 V wide input range
- Fixed 5.0 V output for direct use without external resistor divider
- Precision enable pin allows accurate power sequencing and soft-start control
- AEC-Q100 automotive qualification for under-hood and body electronics
- PWM voltage-mode control ensures stable regulation across load transients
What is LM22674QMRE-5.0/NOPB used for?
The LM22674QMRE-5.0/NOPB is widely used in automotive ECU power stages that step down a 12 V or 24 V vehicle battery to a regulated 5 V logic supply rail for sensors and microcontrollers. Its 42 V input tolerance handles load-dump transients common in 12 V automotive systems without additional clamping components. Industrial equipment and 24 V DIN-rail power supplies also employ it for point-of-load 5 V conversion with a 500 mA current budget.

Frequently Asked Questions
How much output current can LM22674QMRE-5.0/NOPB deliver, and what input voltage range does it support?
The LM22674QMRE-5.0/NOPB delivers up to 500 mA of continuous output current from a 4.5 V to 42 V input supply. The wide 42 V input tolerance is particularly useful in 12 V automotive environments where load-dump transients can spike to 40 V. The regulator maintains a stable 5.0 V output throughout the full input range without requiring external voltage clamping.
Which automotive applications benefit from the precision enable pin in LM22674QMRE-5.0/NOPB?
The precision enable pin is valuable in automotive body control modules and ADAS power domains where supply sequencing must occur within a defined 1 ms to 10 ms window. By driving the enable threshold precisely, designers can coordinate the 5 V rail startup relative to 3.3 V or 1.8 V secondary rails, preventing latch-up in FPGA and SoC power domains that require ordered sequencing.
Is LM22674QMRE-5.0/NOPB compliant with AEC-Q100 automotive reliability standards?
Yes, the LM22674QMRE-5.0/NOPB is AEC-Q100 qualified for automotive applications, supporting a -40°C to 125°C junction temperature range. The Q-grade qualification ensures it passes accelerated life testing, HTOL, and ESD stress above 2 kV HBM, making it suitable for underhood environments in engine control units and transmission control modules.
How does the LM22674QMRE-5.0/NOPB compare to linear regulators for 12 V to 5 V conversion in automotive designs?
Unlike a linear regulator that dissipates (12 V - 5 V) × 500 mA = 3.5 W as heat, the LM22674QMRE-5.0/NOPB achieves typical efficiencies above 85%, reducing power loss to under 0.5 W at 500 mA load. This eliminates the need for a heatsink and reduces PCB thermal area by 60% to 70%, enabling more compact automotive module designs without thermal management overhead.
