Product details
Overview
LP5907285QDQNRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified low-dropout linear regulator delivering 250 mA output current at a fixed 2.85 V with ultra-low 6.5 µVRMS output noise, 82 dB PSRR at 1 kHz, and 12 µA quiescent current - designed for powering noise-sensitive RF and analog circuits in ADAS camera modules.
For engineers reviewing the LP5907285QDQNRQ1 datasheet, LP5907285QDQNRQ1 pinout, LP5907285QDQNRQ1 application, or LP5907285QDQNRQ1 equivalent, key selection considerations include its X2SON-4 package footprint, remote output capacitor support up to 10 cm, no-bypass-capacitor noise performance, and thermal shutdown behavior at 160°C junction temperature.
Technical Context
The LP5907285QDQNRQ1 employs a proprietary low-noise reference architecture with integrated RC filtering (–3 dB at ~0.1 Hz) to suppress internal bandgap noise before amplification, enabling <6.5 µVRMS output noise without external bypass capacitors. Its enable circuit includes a 1-MΩ internal pulldown resistor and VIH/VIL thresholds of 1.2 V/0.4 V for robust automotive logic interfacing.
It operates across 2.2 V–5.5 V input range with 120 mV typical dropout at 250 mA, supports stable regulation using only 1-µF ceramic input and output capacitors, and features active output discharge via a 230-Ω internal pulldown when disabled - critical for power sequencing in safety-critical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 2.85 V ±2% (X2SON package), ensuring precise rail generation for image sensor analog front-ends. |
| Max output current | 250 mA continuous, sufficient for dual-lane MIPI CSI-2 camera sensor power domains. |
| Output noise | <6.5 µVRMS (10 Hz–100 kHz), eliminates need for dedicated noise-bypass capacitor in space-constrained PCB layouts. |
| PSRR | 82 dB at 1 kHz, suppresses switching noise from adjacent DC/DC converters feeding digital cores. |
| Quiescent current | 12 µA (enabled), 0.2–1 µA (disabled), enabling always-on functionality in vehicle wake-up circuits. |
| Dropout voltage | 120 mV typical at 250 mA, allowing operation from 3.0 V input while maintaining 2.85 V output under full load. |
| Enable threshold | VIH = 1.2 V, VIL = 0.4 V, compatible with 1.8 V/3.3 V microcontroller GPIOs without level-shifting. |
Pinout & Package
X2SON-4 package (1.00 mm × 1.00 mm, 0.4 mm height), optimized for high-density automotive PCBs with minimal thermal pad area and no exposed thermal slug.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers stable 2.85 V; supports remote capacitor placement up to 10 cm for mechanical layout flexibility. |
| 2 (GND) | Power ground | Common return path for input, output, and enable; must connect to low-impedance analog ground plane. |
| 3 (EN) | Enable control input | Active-high logic input with 1-MΩ internal pulldown; asserts shutdown and activates 230-Ω output discharge. |
| 4 (IN) | Input supply | Accepts 2.2–5.5 V; requires ≥1-µF ceramic capacitor within 1 cm for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Noise-bypass-capacitor-free operation | Integrated RC-filtered reference enables <6.5 µVRMS noise without external 10-nF capacitor - saves board space and BOM cost. |
| Remote output capacitor support | Stable with 1-µF ceramic cap placed up to 10 cm from OUT pin, enabling placement near load to minimize IR drop and EMI. |
| Active output discharge | 230-Ω internal pulldown discharges VOUT to GND during shutdown, preventing floating rails and ensuring clean power sequencing. |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation with thermal shutdown at 160°C and hysteresis of 15°C - meets ASIL-B system requirements. |
| Ultra-low IQ in shutdown | <1 µA total device current when EN = low, critical for battery-backed always-on ADAS subsystems with multi-year standby life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC7607285QDQNRQ1 | Same X2SON-4 package, but higher 25 µA IQ and 10 µVRMS noise; lacks remote capacitor support. | Suitable for non-RF analog loads where lower cost outweighs noise performance. | Select only if system-level noise budget allows ≥10 µVRMS and layout constraints prohibit remote capacitor routing. |
| TPS7A05285PDBVRQ1 | Higher 200 mA max output, 17 µA IQ, 15 µVRMS noise; SOT-23-5 package (larger footprint). | Better for mixed-signal SoC core rails requiring higher current but less stringent noise specs. | Choose when board space permits SOT-23-5 and load current exceeds 200 mA but noise tolerance is >10 µVRMS. |
Compared with TLC7607285QDQNRQ1 and TPS7A05285PDBVRQ1, the LP5907285QDQNRQ1 delivers superior noise performance and remote capacitor capability in the smallest footprint - making it the optimal choice for space-constrained, RF-critical automotive vision systems.

FAQ
What is the exact output voltage tolerance of LP5907285QDQNRQ1 across temperature and load?
The LP5907285QDQNRQ1 has a guaranteed output voltage tolerance of ±2% over –40°C to +125°C junction temperature, 2.2 V–5.5 V input range, and 1 mA–250 mA load current - verified per AEC-Q100 stress testing and documented in Section 6.5 of the SNVSA34E datasheet for the X2SON-4 package variant.
Does LP5907285QDQNRQ1 require an external noise-bypass capacitor?
No, the LP5907285QDQNRQ1 does not require an external noise-bypass capacitor. Its internal low-pass RC filter (–3 dB at ~0.1 Hz) suppresses reference noise, enabling <6.5 µVRMS output noise with only 1-µF input and output ceramic capacitors - confirmed in Features, Section 7.3.3, and Figure 16 of the LP5907285QDQNRQ1 datasheet.
What is the thermal shutdown behavior of LP5907285QDQNRQ1?
The LP5907285QDQNRQ1 activates thermal shutdown at 160°C junction temperature and re-enables at ~145°C (15°C hysteresis). This protection is internal and independent of external components - detailed in Section 6.5 (TSD parameter) and Section 7.3.6 of the official TI datasheet SNVSA34E.
Can the output capacitor of LP5907285QDQNRQ1 be placed remotely from the IC?
Yes, the LP5907285QDQNRQ1 supports remote placement of its 1-µF output ceramic capacitor up to 10 cm from the OUT pin - a design feature validated in Section 7.3.5 and Figure 20 of the datasheet, enabling optimal placement near noise-sensitive loads like image sensors.
What is the enable pin behavior and internal pull-down value for LP5907285QDQNRQ1?
The LP5907285QDQNRQ1 EN pin has an internal 1-MΩ pull-down resistor to GND, with VIH = 1.2 V (min) and VIL = 0.4 V (max). When pulled low, it disables regulation and activates the 230-Ω internal output pulldown - specified in Pin Functions (Section 5) and Feature 7.3.2 of the SNVSA34E datasheet.
