What are the key features of PS7B8150QDRVRQ1?
- Ultra-low quiescent current enabling always-on standby power rails in automotive ECUs with minimal battery drain
- Wide 5.6 V to 40 V input voltage range (45 V absolute maximum) covering full automotive load dump transient conditions
- Low 325 mV typical dropout voltage at 150 mA output maximizing efficiency in 12 V automotive battery-powered applications
What is PS7B8150QDRVRQ1 used for?
The PS7B8150QDRVRQ1 is designed for automotive always-on power supply rails in body control modules, telematics units, and gateway ECUs that must remain active during engine-off states with minimal battery draw. Its 40 V input rating covers standard 12 V automotive battery voltages plus load dump transients, while the ultra-low quiescent current preserves battery life during prolonged parking or standby periods. The AEC-Q100 qualification and 6-pin SON package support high-reliability automotive production requirements across the full -40°C to 125°C temperature range.

Frequently Asked Questions
How does the PS7B8150QDRVRQ1 handle automotive load dump transients up to 45 V without damage?
The device is rated for an absolute maximum input voltage of 45 V, which covers the ISO 7637 load dump transient levels encountered on 12 V automotive battery rails. The normal operating input range extends to 40 V, providing a 5 V margin below the absolute maximum, ensuring the LDO survives transient spikes without external clamping diodes in most applications.
For an automotive telematics ECU that must stay on during ignition-off, how does the ultra-low quiescent current of this LDO reduce parasitic battery drain?
Always-on automotive systems typically budget a total standby current below 1 mA to preserve battery charge over weeks of vehicle parking. The PS7B8150QDRVRQ1's ultra-low quiescent current in the microampere range ensures that the LDO's own bias current contribution remains negligible within that budget, allowing the telematics module to maintain network connectivity and GPS tracking without discharging a 60 Ah battery prematurely.
What does the 325 mV typical dropout voltage mean for a 5 V output design powered from a low-battery 12 V rail?
A 325 mV typical dropout voltage means the input must remain at least 5.325 V for the 5 V output to stay regulated. On a 12 V automotive rail that may sag to 6 V during cold-crank conditions, the regulator maintains 5 V regulation with 675 mV of headroom remaining. This is significantly better than standard LDOs with 1 V to 2 V dropout, reducing the risk of output dropout during engine starting.
How compact is the 6-pin SON package of the PS7B8150QDRVRQ1, and what are the implications for automotive PCB density?
The 6-pin SON (S-PDSO-N6) package has a typical footprint of approximately 1.5 mm x 1.5 mm, among the smallest available for 150 mA LDOs. This allows placement in tight automotive ECU PCB areas where space is constrained, and the exposed thermal pad on the underside of the package improves heat dissipation, keeping junction temperature within the -40°C to 125°C operating range at full 150 mA output.
