Product details
Overview
MPQ20056GG-33-Z from Monolithic Power Systems is a low-noise, high-PSRR 250mA LDO linear regulator with fixed 3.3V output, AEC-Q100 qualified for automotive applications, 100mV dropout at 250mA, 150μA ground current, and stable operation with ceramic capacitors - deployed in infotainment power rails and ADAS sensor supplies.
For engineers reviewing the MPQ20056GG-33-Z datasheet, MPQ20056GG-33-Z pinout, MPQ20056GG-33-Z application, or MPQ20056GG-33-Z equivalent, key selection criteria include automotive-grade thermal shutdown (150°C), 63dB PSRR at 1kHz, 13μVRMS noise (10Hz–100kHz), and QFN8 (2×2mm) package compatibility with space-constrained PCB layouts.
Technical Context
The MPQ20056GG-33-Z integrates a PMOS pass transistor enabling ultra-low dropout (100mV @ 250mA) and minimal ground current (150μA @ light load). Its feedback loop uses a precision 0.8V reference and supports fast transient response via optimized error amplifier compensation.
It implements dual protection: current limiting (350–850mA short-circuit limit) and thermal shutdown with 20°C hysteresis. The EN pin provides logic-level control (1.5V turn-on threshold), and UVLO activates below 1.95V input to prevent unstable regulation during brownout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% (25°C), ±3% (−40°C to +125°C) - ensures stable core voltage for 3.3V microcontrollers and CAN transceivers. |
| Dropout Voltage | 100mV @ 250mA - enables regulation down to VIN = 3.4V, critical for battery-powered systems operating near end-of-life voltage. |
| PSRR | 63dB @ 1kHz - suppresses switching noise from upstream DC/DC converters feeding sensitive RF or ADC circuitry. |
| Noise (RMS) | 35μVRMS (10Hz–100kHz, VOUT=3.3V) - meets low-noise requirements for analog sensor front-ends and audio codec supplies. |
| Ground Current | 150μA @ IOUT=0.1mA - extends battery life in always-on automotive modules like door controllers and telematics wake-up circuits. |
| Thermal Shutdown | 150°C junction temperature with 20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking in sealed enclosures. |
| Input Voltage Range | 2.5V to 5.5V - compatible with 3.3V and 5V system rails, including post-regulated outputs of buck converters and automotive 12V-derived supplies. |
Pinout & Package
MPQ20056GG-33-Z uses a thermally enhanced 2mm×2mm 8-pin QFN package with exposed thermal pad. The pad must be soldered to a solid GND plane for optimal thermal performance (θJA = 80°C/W on 4-layer PCB).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, Exposed Pad | GND | Primary thermal path and signal return - must connect to internal/external GND plane for <125°C junction temp under full load. |
| 2 | EN | Active-high enable input - logic high ≥1.5V enables regulation; ≤0.4V disables output and reduces supply current to 0.1μA. |
| 3, 4 | IN | Main input supply - accepts 2.5V–5.5V; requires 2.2μF ceramic bypass capacitor placed adjacent to pins 3/4. |
| 5, 6 | OUT | Regulated 3.3V output - stable with 4.7μF ceramic capacitor; pins 5/6 must be externally shorted to handle full 250mA current. |
| 7 | NC | No internal connection - must remain unconnected; floating or tied to any potential violates layout guidelines. |
| 8 | FB | Feedback node - internally connected to fixed 3.3V divider; not accessible for adjustment in this variant. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Rated for −40°C to +125°C junction operation - validated for engine bay and dashboard-mounted automotive electronics. |
| Low-noise architecture | 35μVRMS output noise (10Hz–100kHz) - eliminates need for additional RC filtering in precision analog subsystems. |
| Ceramic-capacitor stability | Guaranteed stability with 4.7μF X5R/X7R ceramic output cap - reduces BOM count and board area vs. tantalum alternatives. |
| Fast load transient response | ≤450μs startup time (10%→90% VOUT) and minimal DC shift under 100mA→250mA step - maintains digital logic integrity during burst-mode operation. |
| Integrated protection | Current limit (350–850mA), thermal shutdown (150°C), and UVLO (1.95V) - eliminates need for external fault management circuitry. |
Applications
| Automotive Infotainment | ADAS Camera Modules |
|---|---|
|

IC Role / Device Role / Timing Role: Always-on LDO with 150μA quiescent current supporting low-power wake-on-CAN functionality. Use Value: Ultra-low ground current extends backup battery life during ignition-off periods; EN pin enables firmware-controlled power gating. |
Use Scenario: Regulating 3.3V for door module MCUs, LIN transceivers, and LED driver ICs in centralized body control units. IC Role / Device Role / Timing Role: Input-supply tolerant LDO accepting 2.5V–5.5V inputs from vehicle battery or local DC/DC converters. Use Value: 100mV dropout allows operation down to 3.4V input - critical during cold-crank events where battery dips to 6V with heavy alternator load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS7B8133QDGNRQ1 | 3.3V fixed, 300mA, 175μA IQ, 170mV dropout, 60dB PSRR @1kHz | Higher dropout and lower PSRR - less suitable for noise-sensitive RF sections but offers higher current margin. | Select when >250mA peak load is required and PSRR >60dB is not mandatory. |
| ON Semiconductor NCP1117ST33T3G | 3.3V fixed, 800mA, 6mA IQ, 1.2V dropout, no AEC-Q100 grade | Non-automotive grade, much higher ground current and dropout - unsuitable for battery-backed or low-noise automotive use. | Only consider for cost-sensitive industrial non-automotive designs where AEC-Q100 and low IQ are not required. |
Compared with TPS7B8133QDGNRQ1, MPQ20056GG-33-Z delivers 3dB better PSRR and 100mV lower dropout at same load, enabling tighter noise budgets and longer battery runtime; versus NCP1117ST33T3G, it provides AEC-Q100 compliance and 40× lower quiescent current - essential for automotive always-on domains.

FAQ
Is MPQ20056GG-33-Z pin-compatible with other MPQ20056 variants?
No - MPQ20056GG-33-Z uses the QFN8 (2×2mm) package with dual IN and dual OUT pins, while TSOT23-5 variants (e.g., MPQ20056GJ-33-Z) have single IN/OUT pins and different pin mapping. Layouts are not interchangeable without redesign.
What is the maximum allowable power dissipation for MPQ20056GG-33-Z at 85°C ambient?
With θJA = 80°C/W and TJ(MAX) = 150°C, maximum continuous power dissipation is (150°C − 85°C) / 80°C/W = 0.81W. At 3.3V output and 250mA load, power dissipation is (VIN − 3.3V) × 0.25A - VIN must stay ≤ 6.5V to remain within thermal limits.
Can MPQ20056GG-33-Z be used with input voltages below 2.5V?
No - absolute minimum input is 2.5V per datasheet specifications. Below this, UVLO engages (threshold 1.95V rising), and regulation is not guaranteed. Operation at 2.4V may cause output collapse or instability.
Does MPQ20056GG-33-Z require an external feedback resistor network?
No - the "-33" suffix denotes fixed 3.3V output; FB pin is internally connected to the precision voltage divider. External resistors are only needed for adjustable versions (e.g., MPQ20056GJ-Z without voltage suffix).
What is the recommended output capacitor for MPQ20056GG-33-Z?
A 4.7μF X5R or X7R ceramic capacitor with ≤100mΩ ESR is recommended and sufficient for stability and transient response. Larger values (e.g., 10μF) improve load step recovery but increase board area and cost without significant noise benefit.
How does the EN pin behave during power-up sequences?
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 it. Floating EN causes undefined behavior - tie to VIN via 100kΩ resistor if always-on operation is required.
Is reverse voltage protection integrated into MPQ20056GG-33-Z?
No - the internal PMOS body diode conducts from OUT to IN if VOUT > VIN, risking damage from uncontrolled reverse current. An external Schottky diode (cathode to IN, anode to GND) is required in backup-battery or hot-swap scenarios.
