Key Features
- Ultra-low quiescent current enables always-on 5 V or 3.3 V standby rail operation from a 12 V automotive battery with negligible dark current drain over months of vehicle storage
- 6.17 V to 40 V input range with 45 V absolute maximum handles automotive load dump transients without external protection components
- 300 mA output current with only 0.4 V typical dropout supports direct battery regulation on 5 V fixed output rails in body electronics modules
Applications
TPS7B8250EPWPRQ1 is designed for automotive body electronics, door modules, and always-on telematics units that must maintain a stable 5 V rail directly from the vehicle battery with minimal parasitic drain. Its ultra-low quiescent current preserves battery charge during vehicle park-off periods in remote keyless entry and passive entry systems. The 40 V input tolerance also protects against 12 V battery load dump events without additional clamping circuitry.

Frequently Asked Questions
How does TPS7B8250EPWPRQ1 handle automotive load dump transients up to 45 V?
TPS7B8250EPWPRQ1 has an absolute maximum input voltage rating of 45 V, which covers ISO 7637-2 automotive load dump pulses that can reach 40 V for up to 400 ms when an alternator disconnects its battery load. Operating with a normal 6.17 V to 40 V input range, no external TVS clamping diode is required for compliance with standard automotive 12 V system transient requirements.
What is the quiescent current of TPS7B8250EPWPRQ1 in always-on automotive standby applications?
TPS7B8250EPWPRQ1 features ultra-low quiescent current suitable for always-on 5 V standby rails that must not drain a 50 Ah automotive battery below 11 V over 30 days of vehicle storage. At the rated quiescent current, the total annual dark current drain from a 12 V battery remains well under 1% of capacity, meeting typical OEM park-off current budgets of under 5 mA for body electronics modules.
Can TPS7B8250EPWPRQ1 regulate directly from a 12 V automotive battery to a 5 V rail without additional components?
TPS7B8250EPWPRQ1 supports a 6.17 V to 40 V input range and delivers a fixed 5 V output at up to 300 mA with only 0.4 V typical dropout, so it connects directly to a 12 V nominal battery through an input capacitor and output capacitor without an external pre-regulator. The enable pin also allows a microcontroller to gate the 5 V rail on or off for load switching, reducing total system idle power below 1 mW.
Which automotive qualification does TPS7B8250EPWPRQ1 meet for powering ADAS and body control applications?
TPS7B8250EPWPRQ1 carries AEC-Q100 Grade 1 qualification, confirming device reliability across -40°C to 125°C junction temperature. This certification satisfies OEM supplier requirements for body control modules, door ECUs, and telematics control units where long-term reliability over 15 years and 150,000 km vehicle lifetime must be demonstrated during component qualification.
