Shenzhen Mingjiada Electronics Co., Ltd. — Supplier of Texas Instruments TPS7B8401QWDRBRQ1 Automotive-Grade Low Dropout Linear Regulator

Product Overview  

The Texas Instruments (TI) TPS7B8401QWDRBRQ1 is an AEC-Q100-certified automotive-grade low-dropout linear regulator specifically designed for 12V/24V automotive battery systems, providing a stable and efficient power management solution. This device features ultra-low quiescent current and high input voltage tolerance (up to 40V), making it suitable for applications such as body electronics, infotainment systems, ADAS, and in-vehicle networks.

Key Advantages:

✅ Wide input voltage range (4V-40V), compatible with 12V/24V automotive battery systems

✅ Ultra-low quiescent current (typical value 3.5μA), significantly reducing standby power consumption

✅ High-precision output (±1.5%), ensuring stable power supply for critical loads

✅ Compliant with AEC-Q100 Grade 1 standard (-40°C to +125°C operating temperature)
