- Adjustable output voltage from 1.5V to 6V input range supports diverse ADAS and infotainment rail requirements from a single part
What is PPS74601PQWDRBRQ1 used for?
PPS74601PQWDRBRQ1 is designed for automotive electronic control units, ADAS processor boards, and infotainment systems requiring a clean, low-noise 1A supply rail from a battery-backed bus. Its high PSRR suppresses switching noise from adjacent DC/DC converters on shared automotive power buses, protecting sensitive microcontrollers and radar front-end ICs. The integrated power-good signal also supports controlled power sequencing in multi-rail automotive SoC platforms where rail order is critical for safe startup.

Frequently Asked Questions
How does PPS74601PQWDRBRQ1's 0.895V dropout voltage benefit automotive 3.3V rail designs powered from a 4.2V post-regulator bus?
With a typical dropout voltage of 0.895V at 1A, the PPS74601PQWDRBRQ1 maintains full 3.3V regulation from an input as low as approximately 4.2V, leaving only 900mV of headroom. This means a 4.2V buck converter output can directly drive the LDO without a voltage boost stage, reducing the power conversion chain to two components. In automotive infotainment designs where the 4.2V rail is derived from a 5V pre-regulator, this 0.895V dropout allows continuous 3.3V output even during input sag without dropout-induced reset events.
For an automotive radar front-end requiring sub-100µV output noise, how does PPS74601PQWDRBRQ1's high PSRR help compared to a standard LDO?
PPS74601PQWDRBRQ1's high PSRR attenuates input supply noise by 60dB or more at audio and switching frequencies, translating a 100mV ripple on the 5V input to less than 0.1mV at the regulated output. Standard LDOs with 40dB PSRR would pass 1mV of that same ripple, which can inject false targets into 77GHz radar ADC inputs at sub-millivolt sensitivity thresholds. The additional 20dB rejection eliminates the need for a separate LC post-filter stage on the radar supply rail, saving board space in compact ADAS modules.
How does the integrated power-good signal in PPS74601PQWDRBRQ1 enable safe rail sequencing in a multi-rail automotive ECU?
The power-good open-drain output of PPS74601PQWDRBRQ1 asserts high when the regulated output is within 92% of its nominal voltage, providing a ready signal that a sequencing supervisor or GPIO can use to enable downstream rails. In a 3-rail automotive ECU where the 1.8V core must be stable before the 3.3V I/O and 5V peripheral rails are enabled, chaining the LDO's power-good to the next regulator's enable pin ensures proper 10ms to 50ms startup sequencing without a dedicated sequencer IC, reducing BOM cost by one component.
Is PPS74601PQWDRBRQ1 AEC-Q100 qualified and what temperature range does it cover for underhood automotive use?
Yes, PPS74601PQWDRBRQ1 is AEC-Q100 qualified for automotive applications, covering an operating junction temperature range of -40°C to 125°C. This Grade 1 temperature qualification makes it suitable for underhood and passenger compartment automotive modules where ambient temperatures can swing from arctic cold soak to engine heat soak extremes. The AEC-Q100 stress testing also includes HTOL, HAST, and ESD robustness, ensuring long-term reliability over a 15-year automotive product lifetime.
