Product details
Overview
MPQ20056GJ-33-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 3.3V output. It operates from 2.5V–5.5V input and targets power-sensitive automotive infotainment and ADAS domain controllers requiring stable low-noise bias for RF receivers and precision analog circuitry.
For engineers reviewing the MPQ20056GJ-33-AEC1-Z datasheet, MPQ20056GJ-33-AEC1-Z pinout, MPQ20056GJ-33-AEC1-Z application, or MPQ20056GJ-33-AEC1-Z equivalent, this page provides verified package mapping (TSOT23-5), thermal resistance (θJA = 220°C/W), PSRR (63dB @1kHz), noise (35μVRMS @3.3V), and AEC-Q100 compliance details essential for automotive-grade LDO selection.
Technical Context
The MPQ20056GJ-33-AEC1-Z uses an internal PMOS pass transistor enabling ultra-low dropout (100mV @250mA) and minimal ground current (150μA @0.1mA load). Its feedback loop is optimized for stability with standard 4.7μF ceramic output capacitors and delivers fast transient response under dynamic load steps typical in automotive microcontroller core rails.
It integrates EN-controlled shutdown (EN threshold: 1.5V logic high), thermal shutdown (150°C trip, 20°C hysteresis), and current limiting (350–850mA short-circuit limit). The fixed 3.3V output version eliminates external resistor divider components while maintaining ±3% output accuracy across –40°C to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±3% over –40°C to +125°C; enables direct replacement of legacy 3.3V LDOs without resistor network redesign. |
| Max Output Current | 250mA continuous; sufficient for powering single-core automotive MCUs, CAN transceivers, or sensor signal chains. |
| Dropout Voltage | 100mV @250mA, 25°C; allows operation down to 3.4V input when regulating 3.3V, critical for cold-crank battery scenarios. |
| Ground Current | 150μA @0.1mA load; minimizes quiescent drain in always-on vehicle modules like body control units. |
| Output Noise | 35μVRMS (10Hz–100kHz) @3.3V; meets stringent noise requirements for RF front-end biasing in telematics modules. |
| PSRR | 63dB @1kHz; suppresses switching noise from adjacent DC/DC converters feeding shared 5V rail. |
| Thermal Shutdown | 150°C trip with 20°C hysteresis; protects against sustained overload in sealed ECU enclosures with limited airflow. |
Pinout & Package
MPQ20056GJ-33-AEC1-Z is housed in a RoHS-compliant TSOT23-5 package (2.9mm × 1.6mm × 1.1mm height) with exposed pad not present - thermal path relies on PCB copper area under pins. Pin 1 (IN) accepts 2.5V–5.5V input; Pin 5 (OUT) delivers regulated 3.3V; Pin 4 (FB) is internally tied to 3.3V divider and unused; Pin 3 (EN) enables logic-controlled shutdown; Pin 2 (GND) connects to system ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Supply Rail | Accepts 2.5V–5.5V; requires ≥2.2μF ceramic bypass capacitor close to pin for stability and noise rejection. |
| 2 (GND) | Power Ground Reference | Low-impedance return path for regulator current; must connect directly to main system ground plane. |
| 3 (EN) | Enable Control Input | Logic-high (>1.5V) enables regulation; logic-low (<0.4V) disables output and reduces supply current to 0.1μA. |
| 4 (FB) | Feedback Input | Internally connected to fixed 3.3V divider; left unconnected - no external resistors required. |
| 5 (OUT) | Regulated Output | Delivers 3.3V ±3%; requires ≥4.7μF ceramic output capacitor for transient response and noise filtering. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive ambient temperatures from –40°C to +125°C, supporting under-hood and cabin ECU deployment. |
| Low 150μA ground current | Enables >10-year battery life in always-on vehicle modules such as smart key receivers and tire pressure sensors. |

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 | 350mA output, 175mV dropout @350mA, 25μVRMS noise, θJA = 214°C/W | Higher current capacity but larger 8-pin VSSOP package; lower noise suits premium audio systems | Select when >250mA load margin or sub-25μVRMS noise is required; verify PCB layout for thermal pad attachment. |
| ON Semi NCP1117ST33T3G | 800mA output, 1.2V dropout @800mA, 40μVRMS noise, non-AEC-Q100, TO-220/TO-263 packages | Larger thermal footprint; lacks automotive qualification and low-noise optimization | Only suitable for non-automotive industrial use; avoid in AEC-Q100 designs due to missing qualification and higher dropout. |
Compared with TPS7B8133QDGNRQ1, MPQ20056GJ-33-AEC1-Z offers smaller TSOT23-5 footprint and lower ground current (150μA vs. 220μA), while NCP1117ST33T3G lacks AEC-Q100 validation and cannot meet cold-crank dropout requirements below 3.4V input.

FAQ
What is the maximum allowable input voltage for MPQ20056GJ-33-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 damage the PMOS pass element. For automotive applications with load-dump transients, external clamping protection is advised.
Does MPQ20056GJ-33-AEC1-Z require an external feedback resistor network?
No. The "-33" suffix denotes a factory-trimmed fixed 3.3V output version. Pin 4 (FB) is internally connected to the precision voltage divider and must be left unconnected. No external resistors are needed, simplifying layout and eliminating drift-related inaccuracies.
How does the EN pin behave during power-up sequences?
The EN pin has a 1.5V threshold for activation and 0.4V for deactivation, with hysteresis to prevent chatter. During slow-rising VIN, EN must be held low until VIN stabilizes above 2.5V, then driven high. Floating EN is prohibited - tie to VIN via 100kΩ resistor if always-on operation is required.
Can MPQ20056GJ-33-AEC1-Z drive a 4.7μF ceramic capacitor safely?
Yes. The device is explicitly characterized and guaranteed stable with 4.7μF X5R/X7R ceramic capacitors (ESR <10mΩ). Larger values improve transient response but increase inrush current; smaller values risk instability. Avoid high-ESR electrolytics or unbuffered MLCCs without derating.
What thermal derating applies when using MPQ20056GJ-33-AEC1-Z on a 2-layer PCB?
On a standard 2-layer board with 1-in² 1oz copper pour under the TSOT23-5, θJA rises from the datasheet's 220°C/W (4-layer) to ~280°C/W. At 250mA and 5.5V input, power dissipation is 525mW, resulting in ~147°C junction rise - exceeding 125°C max. Use thermal vias and larger copper area to maintain safe TJ.
Is reverse voltage protection integrated into MPQ20056GJ-33-AEC1-Z?
No. The internal PMOS pass element includes a body diode that conducts from OUT to IN if VOUT > VIN (e.g., backup battery scenario). This uncontrolled reverse current can damage the IC. An external Schottky diode (cathode to IN, anode to GND) or ideal diode controller is mandatory in such configurations.
How is AEC-Q100 Grade 1 compliance verified for MPQ20056GJ-33-AEC1-Z?
Compliance is confirmed per AEC-Q100-001 through -004 stress tests including HTOL (1000h @125°C), TC (1000 cycles -40°C to +125°C), and UHAST (96h @130°C/85% RH). The "-AEC1" suffix certifies full qualification; test reports are available under NDA from MPS upon request.
