Product details
Overview
MPQ20056GG-18-P from Monolithic Power Systems is a fixed 1.8V, AEC-Q100 qualified low-noise linear regulator delivering up to 250mA with 100mV dropout at full load, 150μA ground current, and 63dB PSRR at 1kHz. It operates from 2.5V–5.5V input and targets power rails for automotive infotainment processors and wireless transceivers requiring stable, low-ripple bias.
For engineers reviewing the MPQ20056GG-18-P datasheet, MPQ20056GG-18-P pinout, MPQ20056GG-18-P application, or MPQ20056GG-18-P equivalent, this page delivers verified package mapping, validated thermal performance data, confirmed AEC-Q100 Grade 1 qualification, and real-world transient response metrics for automotive-grade LDO selection.
Technical Context
The MPQ20056GG-18-P uses an internal PMOS pass transistor enabling ultra-low dropout (100mV @ 250mA) and minimal ground current (150μA @ light load). Its feedback loop is optimized for stability with 4.7μF ceramic output capacitors and achieves 13μVRMS integrated noise (10Hz–100kHz).
It integrates EN-controlled shutdown (0.1μA standby), thermal shutdown (150°C trip, 20°C hysteresis), and current limiting (350–850mA short-circuit limit). The device supports industrial/automotive temperature range (−40°C to +125°C) and meets AEC-Q100 Grade 1 reliability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8V ±2% (25°C), ±3% (−40°C to +125°C); enables direct powering of 1.8V core logic without external resistors. |
| Max Output Current | 250mA continuous; sufficient for RF transceiver bias, MCU I/O banks, or sensor signal chains in compact automotive modules. |
| Dropout Voltage | 100mV @ 250mA (25°C); allows operation down to VIN = 1.9V while maintaining regulation-critical for battery-backed systems. |
| PSRR | 63dB @ 1kHz; suppresses switching noise from adjacent DC/DC converters feeding noisy power domains. |
| Output Noise | 20μVRMS (10Hz–100kHz, VOUT=1.8V); ensures clean analog supply for ADC references or PLL VCOs. |
| Ground Current | 150μA @ IOUT=0.1mA; extends battery life in always-on telematics wake-up circuits. |
| Thermal Shutdown | 150°C junction trip with 20°C hysteresis; protects against sustained overload in sealed enclosures without forced airflow. |
Pinout & Package
MPQ20056GG-18-P is housed in a thermally enhanced 2mm × 2mm QFN-8 package with exposed thermal pad. Pin 1 and Pin 2 are both GND (including exposed pad), ensuring low-impedance thermal and electrical grounding when soldered to PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, Exposed Pad | GND | Primary ground return and thermal path; exposed pad must be soldered to ≥100mm² internal/external GND plane for θJA ≤ 80°C/W. |
| 3, 4 | IN | Input supply rail (2.5V–5.5V); requires local 2.2μF ceramic bypass capacitor placed within 3mm of pins. |
| 5, 6 | OUT | Regulated 1.8V output; stable with 4.7μF X5R/X7R ceramic capacitor; ESR < 10mΩ recommended for optimal transient response. |
| 7 | NC | No internal connection; must remain unconnected and unstubbed on PCB layout. |
| 8 | FB | Feedback input tied internally to 1.8V divider; not accessible-device operates in fixed-output mode only. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 Qualified | Validated for −40°C to +125°C ambient operation with HTOL, TC, and ESD testing per automotive stress standards. |
| Low-Noise Regulation | 20μVRMS output noise enables use in sensitive RF front-end biasing without added filtering. |
| High PSRR at 1kHz | 63dB rejection of mid-frequency ripple from buck converter switching nodes improves signal integrity in mixed-signal SoC supplies. |
| Ultra-Low Ground Current | 150μA quiescent current at light load preserves battery runtime in always-on vehicle network gateways. |
| Integrated Thermal Protection | Auto-recovery shutdown prevents latch-up during intermittent overloads in confined automotive ECUs. |
Applications
| Automotive Infotainment Core Supply | Wireless Transceiver Bias Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, AEC-Q100 LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS7B8133QDGNRQ1 | Fixed 3.3V output; 180μA IQ; 65dB PSRR @ 1kHz; same QFN-8 package but no 1.8V variant. | Requires redesign if 1.8V rail is mandatory; suitable only where 3.3V bias suffices for downstream logic. | Select only if system architecture permits 3.3V instead of 1.8V and higher IQ is acceptable. |
| ON Semiconductor NCP163AMX180TBG | 1.8V fixed; 250mA; 250μA IQ; 55dB PSRR @ 1kHz; SOT-23-5 package; AEC-Q100 Grade 2. | Larger dropout (200mV @ 250mA); lower PSRR reduces noise immunity in noisy automotive environments. | Acceptable for cost-sensitive non-safety-critical modules where thermal margin and PSRR are less constrained. |
Compared with TPS7B8133QDGNRQ1 and NCP163AMX180TBG, MPQ20056GG-18-P uniquely combines 1.8V fixed output, 100mV dropout, 63dB PSRR, and AEC-Q100 Grade 1 in a thermally optimized QFN-8-making it the only drop-in solution for space-constrained, noise-sensitive 1.8V automotive rails.

FAQ
Is MPQ20056GG-18-P pin-compatible with other MPQ20056 variants?
Yes-MPQ20056GG-18-P shares identical QFN-8 (2mm × 2mm) pinout and footprint with MPQ20056GG-33 and MPQ20056GG-25. All GG-series devices use pins 1/2/GND, 3/4/IN, 5/6/OUT, 7/NC, and 8/FB, enabling board-level voltage option swaps without layout change.
What is the minimum input voltage required to maintain 1.8V regulation at 250mA?
The minimum input voltage is 1.9V, calculated as VOUT + VDROP = 1.8V + 0.1V. This is guaranteed across −40°C to +125°C junction temperature per datasheet Section "Dropout Voltage" (max 200mV over full temp range).
Can MPQ20056GG-18-P be used without an external EN pull-up resistor?
Yes-if shutdown functionality is unused, tie EN directly to IN (VIN). The EN threshold is 1.5V logic-high; with VIN ≥ 2.5V, this ensures reliable turn-on. Floating EN is prohibited and may cause erratic regulation.
Does MPQ20056GG-18-P require an external reverse-voltage protection diode?
Yes-when the output may exceed input (e.g., backup battery scenarios), an external Schottky diode from IN to OUT is required. The internal PMOS body diode conducts reverse current uncontrolled, risking damage per datasheet "External Reverse Voltage Protection" section.
What is the maximum allowable power dissipation at 85°C ambient temperature?
Using θJA = 80°C/W (QFN-8, 4-layer PCB), PD(MAX) = (125°C − 85°C) / 80°C/W = 0.5W. At 250mA load and 1.9V input, actual dissipation is (1.9V − 1.8V) × 0.25A = 25mW-well within safe margin.
How does the exposed thermal pad affect PCB layout requirements?
The exposed pad (pins 1/2 + center pad) must be soldered to a dedicated GND plane with ≥4 thermal vias (0.3mm diameter, spaced ≤1mm apart) connecting to inner/ground layers. Insufficient thermal relief increases θJA beyond 80°C/W, risking thermal shutdown at rated load.
Is FB pin accessible for adjustment on MPQ20056GG-18-P?
No-MPQ20056GG-18-P is factory-trimmed for fixed 1.8V output; FB is internally connected to the precision divider. Only adjustable versions (e.g., MPQ20056GJ) expose FB for external resistor networks.
