Product details
Overview
LP590713QDQNRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified low-dropout linear regulator delivering 250 mA output current 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 cameras and radar modules.
For engineers reviewing the LP590713QDQNRQ1 datasheet, LP590713QDQNRQ1 pinout, LP590713QDQNRQ1 application, or LP590713QDQNRQ1 equivalent, key selection considerations include its 1.3 V fixed output voltage, X2SON-4 package with remote capacitor support, thermal shutdown at 160°C, and no external noise bypass capacitor requirement.
Technical Context
The LP590713QDQNRQ1 implements a PMOS pass transistor architecture enabling low dropout (120 mV typical at 250 mA) and near-zero reverse leakage during disable. Its internal reference employs a first-order RC filter (–3 dB at ~0.1 Hz) to suppress bandgap noise before amplification, directly enabling <6.5 µVRMS output noise without external filtering.
It integrates an enable pin with 1-MΩ internal pulldown, VIH = 1.2 V, VIL = 0.4 V, and automatic output discharge via 230-Ω internal pulldown when disabled - supporting clean power sequencing in automotive infotainment and telematics systems operating from –40°C to 125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.3 V ±2% (X2SON-4 package), enabling direct supply to 1.3 V core logic or I/O rails without external feedback. |
| Max Output Current | 250 mA continuous - sufficient for powering image signal processors (ISPs), RF transceivers, or sensor interfaces in compact automotive modules. |
| Output Noise | <6.5 µVRMS (10 Hz–100 kHz) - eliminates need for external noise-bypass capacitor, reducing BOM count and PCB area. |
| PSRR | 82 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding ADAS camera power trees. |
| Quiescent Current | 12 µA (enabled), <1 µA (disabled) - extends battery runtime in always-on telematics and ECU wake-up circuits. |
| Dropout Voltage | 120 mV typical at 250 mA - supports operation down to VIN = 1.42 V, critical for cold-crank scenarios in 12 V automotive systems. |
| Enable Threshold | VIH = 1.2 V, VIL = 0.4 V - compatible with 1.8 V and 3.3 V microcontroller GPIOs for precise power sequencing control. |
Pinout & Package
X2SON-4 package (1.00 mm × 1.00 mm, 0.4 mm height) with wettable flanks for automated optical inspection - optimized for space-constrained automotive camera modules and radar front-ends.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers stable 1.3 V; supports remote placement of 1-µF ceramic capacitor up to 10 cm away 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 internal 230-Ω pulldown on OUT when pulled low for fast discharge. |
| 4 (IN) | Input voltage supply | Accepts 2.2 V–5.5 V; requires ≥1-µF ceramic capacitor within 1 cm for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - meets functional safety requirements for ASIL-B automotive subsystems. |
| No external noise bypass capacitor | Integrated RC-filtered reference reduces output noise to <6.5 µVRMS, eliminating one passive component and associated layout risk. |
| Remote output capacitor support | Enables 1-µF ceramic cap placement up to 10 cm from device - simplifies routing in multi-layer camera PCBs with constrained top-side real estate. |
| Thermal shutdown with hysteresis | Shuts down at 160°C junction temp; re-enables at ~145°C - protects against sustained overload while preventing thermal cycling instability. |
| Ultra-low IQ in shutdown | <1 µA total device current when EN = low - preserves battery charge in parked-vehicle telematics and GPS tracking applications. |
Applications
| ADAS Camera Power Supply | Radar Signal Chain Biasing |
|---|---|
|

IC Role / Device Role / Timing Role: Primary core regulator enabling low-power sleep modes and fast wake-up response. Use Value: 80 µs turn-on time supports rapid system boot; thermal shutdown protects against prolonged overcurrent in CAN bus interface circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLD5098EL | 40 V input, 150 mA output, integrated watchdog timer - not pin-compatible; larger SOIC-8 package. | Designed for LED driver biasing, not RF/analog supply; lacks ultra-low noise spec. | Select only if high-voltage input (>5.5 V) or system monitoring features are required. |
| TPS78013QWDRBRQ1 | 1.3 V fixed, 150 mA, 0.5 µA IQ - smaller IQ but lower current rating and no remote capacitor support. | Better for ultra-low-power MCU peripherals; insufficient for 250 mA ISP loads. | Choose when load current ≤150 mA and minimum IQ dominates design priority over noise performance. |
Compared with TLD5098EL and TPS78013QWDRBRQ1, the LP590713QDQNRQ1 uniquely balances 250 mA drive capability, 6.5 µVRMS noise, and X2SON-4 footprint - making it the only qualified option for space-constrained, noise-critical 1.3 V rails in ADAS vision systems.

FAQ
What is the exact output voltage of LP590713QDQNRQ1?
The LP590713QDQNRQ1 provides a fixed 1.3 V output voltage with ±2% tolerance over temperature and load. This value is laser-trimmed during manufacturing and specified for the X2SON-4 package variant per TI's SNVSA34E datasheet revision December 2019. The "13" in the part number explicitly denotes the 1.3 V option.
Does LP590713QDQNRQ1 require an external noise bypass capacitor?
No, the LP590713QDQNRQ1 does not require an external noise bypass capacitor. Its internal reference stage includes a first-order RC filter (–3 dB at ~0.1 Hz) that suppresses bandgap noise, enabling <6.5 µVRMS output noise with only a 1-µF ceramic output capacitor - a key differentiator confirmed in Section 7.3.3 of the official datasheet.
What package type and dimensions does LP590713QDQNRQ1 use?
The LP590713QDQNRQ1 uses the X2SON-4 package: 1.00 mm × 1.00 mm body size, 0.4 mm maximum height, with wettable flanks. Pin configuration is OUT–GND–EN–IN (top view). This package is documented in Table "Device Information" and Figure 5 of the SNVSA34E datasheet.
How does the enable function operate on LP590713QDQNRQ1?
The LP590713QDQNRQ1 EN pin is internally pulled down with a 1-MΩ resistor. It enables the regulator when voltage exceeds 1.2 V (VIH) and disables it below 0.4 V (VIL). During disable, a 230-Ω internal pulldown discharges the output - ensuring rapid, controlled shutdown essential for automotive power sequencing.
Is LP590713QDQNRQ1 qualified for automotive applications?
Yes, the LP590713QDQNRQ1 is AEC-Q100 Grade 1 qualified for automotive use, with guaranteed operation from –40°C to +125°C junction temperature. This qualification covers thermal shutdown (160°C), ESD robustness (±2000 V HBM), and lifetime reliability testing - fully documented in Section 1 of the SNVSA34E production datasheet.
