Product details
Overview
MPQ20056GJ-Z from Monolithic Power Systems is an AEC-Q100 qualified low-noise, high-PSRR linear regulator delivering up to 250mA output with 100mV dropout at full load, 150μA ground current, and fixed 1.8V output in a TSOT23-5 package-designed for power-sensitive automotive infotainment and ADAS sensor rails.
For engineers reviewing the MPQ20056GJ-Z datasheet, MPQ20056GJ-Z pinout, MPQ20056GJ-Z application, or MPQ20056GJ-Z equivalent, key selection criteria include its 63dB PSRR at 1kHz, ±2% output accuracy over -40°C to +125°C, ceramic-capacitor stability, and integrated thermal/short-circuit protection without external components.
Technical Context
The MPQ20056GJ-Z employs a PMOS pass transistor architecture enabling ultra-low dropout (100mV @ 250mA) and minimal ground current (150μA @ light load), critical for battery-backed systems. Its feedback loop uses a precision 0.8V reference with internal resistor divider for fixed 1.8V output.
It integrates UVLO (1.95V rising threshold, 160mV hysteresis), logic-level enable control (EN threshold: 1.5V high / 0.4V low), and thermal shutdown (150°C trip, 20°C hysteresis). The device operates across 2.5V–5.5V input and maintains regulation down to 1.8V output under full 250mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 250mA continuous - supports microcontroller cores, RF transceivers, and sensor signal chains without derating. |
| Dropout Voltage | 100mV @ 250mA - enables stable 1.8V rail from 2.5V supply, minimizing headroom loss in multi-rail systems. |
| Ground Current | 150μA @ 0.1mA load - extends battery life in always-on automotive modules like CAN wake-up receivers. |
| PSRR | 63dB @ 1kHz - suppresses switching noise from adjacent DC/DC converters feeding noise-sensitive analog circuits. |
| Output Noise | 20μVRMS (10Hz–100kHz) @ 1.8V - meets low-noise requirements for ADC references and PLL VCO supplies. |
| Operating Temp | -40°C to +125°C junction - certified per AEC-Q100 Grade 1, suitable for under-hood and dashboard environments. |
| Input Voltage Range | 2.5V to 5.5V - compatible with 3.3V and 5V system rails, including post-LDO filtered buck outputs. |
Pinout & Package
MPQ20056GJ-Z is housed in a RoHS-compliant TSOT23-5 package (1.0mm height, 2.9mm × 1.6mm footprint) with exposed pad not present-thermal performance relies on PCB copper area under pins 1–5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator Input | Accepts 2.5V–5.5V supply; requires ≥2.2μF ceramic bypass capacitor close to pin for stability and transient response. |
| 2 GND | Ground Reference | Primary return path for load, bias, and feedback currents; must connect directly to low-impedance system ground plane. |
| 3 EN | Enable Control | Logic-compatible input: ≥1.5V enables regulation; ≤0.4V disables output and reduces quiescent current to 0.1μA. |
| 4 FB | Feedback Input | Monitors output via internal 0.8V reference; tied internally to fixed 1.8V divider-no external resistors required. |
| 5 OUT | Regulated Output | Delivers precise 1.8V ±2% (25°C) / ±3% (-40°C to +125°C); requires 4.7μF ceramic output capacitor for stability and noise reduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 Qualified | Validated for automotive applications requiring operation from -40°C to +125°C ambient with full electrical characterization. |
| Low-Noise Regulation | 20μVRMS output noise (10Hz–100kHz) enables clean power for precision analog front-ends and RF ICs. |
| High PSRR at Audio Frequencies | 63dB rejection at 1kHz suppresses ripple from switching regulators powering mixed-signal SoCs. |
| Stable with Ceramic Capacitors | No ESR requirement simplifies BOM and layout-supports compact 0402/0603 4.7μF X5R/X7R MLCCs. |
| Integrated Protection | Thermal shutdown (150°C), short-circuit current limiting (350–850mA), and UVLO prevent fault propagation in harsh environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS7A0518PDBVR | 1.8V fixed, 200mA, 170mV dropout, 25μVRMS noise, no AEC-Q100 rating | Targeted at consumer portables-not qualified for automotive temperature or reliability testing | Select when AEC-Q100 is unnecessary and lower noise (25μVRMS) outweighs current capability |
| ON Semi NCP114AMX18T2G | 1.8V fixed, 300mA, 250mV dropout, 40μVRMS noise, AEC-Q100 Grade 2 (−40°C to +105°C) | Limited to Grade 2 temp range; higher dropout increases thermal load at 2.5V input | Select when higher output current (300mA) is needed and Grade 2 suffices for cabin-mounted modules |
Compared with TPS7A0518PDBVR and NCP114AMX18T2G, MPQ20056GJ-Z uniquely combines AEC-Q100 Grade 1 qualification, 250mA delivery, sub-100mV dropout, and 20μVRMS noise-making it optimal for under-hood and high-reliability ADAS subsystems where thermal margin and noise integrity are non-negotiable.

FAQ
Is MPQ20056GJ-Z pin-compatible with other variants in the MPQ20056 family?
Yes-MPQ20056GJ-Z shares identical TSOT23-5 pinout with all MPQ20056GJ-x variants (e.g., GJ-25, GJ-33, GJ-29), including IN, GND, EN, FB, and OUT assignments. Fixed-output versions use internal feedback dividers; no external resistor changes are needed when swapping voltage options.
What is the minimum input voltage required to maintain 1.8V output at 250mA?
The minimum input voltage is 1.9V: 1.8V nominal output + 100mV guaranteed dropout. At −40°C to +125°C, maximum dropout rises to 200mV, so VIN ≥ 2.0V is recommended for full-temperature-range regulation at full load.
Can MPQ20056GJ-Z be used without an output capacitor?
No-MPQ20056GJ-Z requires a minimum 4.7μF ceramic output capacitor for stability, as confirmed in the datasheet's "Output Capacitor Selection" section. Omitting it risks oscillation, poor transient response, and potential damage during load steps.
Does MPQ20056GJ-Z support reverse-voltage protection?
No-its internal PMOS pass element includes a body diode that conducts from OUT to IN if VOUT > VIN. External reverse-voltage protection (e.g., Schottky diode at input) is mandatory in backup-battery or hot-swap scenarios per Application Note Section 12.
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: tie to VIN for always-on operation, or interface with a microcontroller GPIO. Floating EN causes undefined behavior and may result in erratic startup or failure to regulate.
What is the thermal resistance (θJA) of the TSOT23-5 package under standard JEDEC 4-layer PCB conditions?
The datasheet specifies θJA = 220°C/W for the TSOT23-5 package when mounted on a JEDEC-standard 4-layer PCB (JESD51-7). This value assumes 1-inch² copper pour under the package; adding thermal vias to inner ground planes can reduce effective θJA by up to 40%.
Is the 1.8V output voltage trimmed at final test for accuracy across temperature?
Yes-the datasheet specifies ±2% output accuracy at TJ = 25°C and ±3% over −40°C to +125°C, confirming factory trimming of the internal feedback divider. No external calibration is required for production use within these limits.
