Product details
Overview
MPQ20056GG-18-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified low-noise, high-PSRR linear regulator delivering up to 250mA output current with 100mV dropout at full load, 150μA ground current, and fixed 1.8V output. It operates from 2.5V–5.5V input and targets power rails for automotive infotainment processors, ADAS sensor interfaces, and telematics modules requiring stable low-noise biasing.
For engineers reviewing the MPQ20056GG-18-AEC1-Z datasheet, MPQ20056GG-18-AEC1-Z pinout, MPQ20056GG-18-AEC1-Z application, or MPQ20056GG-18-AEC1-Z equivalent, this part supports automotive-grade thermal robustness (−40°C to +125°C), ceramic-capacitor stability, and integrated short-circuit/thermal protection-key selection criteria for safety-critical embedded power domains.
Technical Context
The MPQ20056GG-18-AEC1-Z uses an internal PMOS pass transistor enabling ultra-low dropout (100mV @ 250mA) and minimal ground current (150μA @ light load). Its feedback architecture centers on a precision 0.8V reference with ±2% output accuracy over temperature and line/load variation.
It integrates UVLO with 1.95V turn-on threshold and 160mV hysteresis, logic-controlled enable (EN pin: 1.5V high, 0.4V low), and thermal shutdown at 150°C with 20°C hysteresis-ensuring fail-safe operation in automotive transients and thermal overload conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8V ±2% at TJ = 25°C; ±3% over −40°C to +125°C-ensures stable core voltage for 1.8V I/O domains. |
| Max Output Current | 250mA continuous-sufficient for powering microcontroller cores, CAN transceivers, or camera sensor analog blocks. |
| Dropout Voltage | 100mV @ 250mA, 25°C-enables regulation down to VIN = 1.9V, critical for battery-backed systems near EOL. |
| Ground Current | 150μA @ IOUT = 0.1mA-minimizes quiescent drain in always-on automotive modules (e.g., body control wake-up circuits). |
| Noise (10Hz–100kHz) | 20μVRMS @ VOUT = 1.8V-low enough to avoid phase noise degradation in RF front-end LDO supplies. |
| PSRR @ 1kHz | 63dB-suppresses switching noise from upstream DC/DC converters feeding noisy 3.3V or 5V rails. |
| Operating Temp | −40°C to +125°C junction-meets AEC-Q100 Grade 1 requirements for under-hood and cabin electronics. |
Pinout & Package
MPQ20056GG-18-AEC1-Z is housed in a thermally enhanced 2mm × 2mm 8-pin QFN package with exposed thermal pad. The pad must be soldered to a PCB ground plane for θJA = 80°C/W and reliable 1.6W power dissipation at TA = 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, Exposed Pad | GND | Primary thermal path and signal return; must connect to large copper pour for thermal management and noise immunity. |
| 2 | EN | Active-high enable input; 1.5V threshold ensures compatibility with 1.8V/3.3V logic; floating prohibited. |
| 3, 4 | IN | Main input supply (2.5V–5.5V); requires 2.2μF ceramic bypass close to pins for stability and transient response. |
| 5, 6 | OUT | Regulated 1.8V output; requires 4.7μF ceramic capacitor to GND for PSRR and load-step performance. |
| 7 | NC | No internal connection; must remain unconnected and unbonded per design-no routing or stitching allowed. |
| 8 | FB | Feedback node tied internally to 1.8V divider; not accessible in fixed-output variant-pin left open. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C operation with HTOL, TC, and ESD testing-required for automotive power ICs. |
| Low-noise 20μVRMS output | Enables clean supply for RF ICs and high-resolution ADCs without external filtering. |
| 63dB PSRR @ 1kHz | Rejects ripple from adjacent buck converters, reducing need for multi-stage filtering in compact ECUs. |
| 150μA ground current | Extends battery life in always-on vehicle networks (e.g., LIN gateway sleep mode). |
| Integrated thermal shutdown | Auto-recovers after 20°C cooldown-prevents latch-up during sustained overload without system-level intervention. |

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; 350mA rating; 225μA IQ; 11μVRMS noise | Higher output voltage; better noise but no 1.8V option-requires redesign if 1.8V rail is mandatory | Select only if system requires 3.3V and lower noise is prioritized over voltage match |
| ON Semi NCP114AMX18T2G | 180mA max; 220μA IQ; 30μVRMS noise; no AEC-Q100 Grade 1 rating | Lower current and unqualified for automotive-suitable only for industrial or consumer derivatives | Acceptable only for non-automotive designs where AEC-Q100 compliance is waived |
Compared with TPS7B8133QDGNRQ1 and NCP114AMX18T2G, MPQ20056GG-18-AEC1-Z uniquely combines 1.8V fixed output, AEC-Q100 Grade 1, 250mA capability, and sub-25μVRMS noise-making it the sole drop-in solution for automotive 1.8V core rail replacement without voltage or qualification compromise.

FAQ
What is the maximum allowable input voltage for MPQ20056GG-18-AEC1-Z?
The absolute maximum input voltage is +6V referenced to GND. However, the recommended operating range is 2.5V to 5.5V. Exceeding 5.5V risks violating safe operating area limits and may trigger internal UVLO or thermal shutdown before reaching the 6V absolute limit.
Can MPQ20056GG-18-AEC1-Z operate with a 2.2V input supply?
No. The device requires a minimum input of 2.5V for guaranteed operation. At 2.2V, the internal UVLO circuit prevents activation-the EN pin will not enable regulation until VIN rises above 1.95V (UVLO rising threshold), and stable 1.8V output requires ≥2.5V input per datasheet specifications.
Is the FB pin accessible for external adjustment on this variant?
No. MPQ20056GG-18-AEC1-Z is a fixed 1.8V output version. The FB pin is internally connected to the resistor divider and must be left unconnected. Only adjustable versions (e.g., MPQ20056GJ) expose FB for external resistor configuration.
Does the exposed thermal pad require solder mask opening?
Yes. The exposed pad must be fully exposed (no solder mask) and connected via multiple thermal vias to an internal or bottom-layer solid GND plane. Omitting this compromises thermal resistance (θJA increases from 80°C/W to >120°C/W), risking thermal shutdown under 250mA load.
How does the EN pin behave during power-up sequencing?
The EN pin has no internal pull-up or pull-down. It must be actively driven to ≥1.5V to enable regulation or ≤0.4V to disable. If left floating, the regulator enters undefined state-potentially oscillating or failing to start. Tie to VIN via 100kΩ resistor if always-on operation is required.
What output capacitor value is required for stability?
A minimum 4.7μF X5R/X7R ceramic capacitor with ≤100mΩ ESR is required at the OUT pin. Smaller values (e.g., 2.2μF) risk instability and poor load-transient response; larger values (10μF) improve transient suppression but increase startup time and board area.
Is reverse voltage protection built-in?
No. The internal PMOS body diode conducts from OUT to IN if VOUT > VIN (e.g., during backup battery hold-up). This uncontrolled current can damage the IC. An external Schottky diode (cathode to IN, anode to GND) is mandatory in such configurations per datasheet Figure 4.
