Monolithic Power Systems Inc. MPQ2013AGQ-25-AEC1-Z

Overview

MPQ2013AGQ-25-AEC1-Z from Monolithic Power Systems is a 40V-input, 2.5V fixed-output AEC-Q100 Grade 1 qualified linear regulator in QFN-8 (3mm×3mm) package, delivering up to 150mA with 3.3µA quiescent current and 620mV dropout at full load. It powers ultra-low-power microcontrollers and automotive body electronics where wide input range and thermal robustness are critical.

For engineers reviewing the MPQ2013AGQ-25-AEC1-Z datasheet, MPQ2013AGQ-25-AEC1-Z pinout, MPQ2013AGQ-25-AEC1-Z application, or MPQ2013AGQ-25-AEC1-Z equivalent, this page delivers verified electrical specs, AEC-Q100 compliance context, thermal shutdown behavior, fixed-output accuracy (±2%), and QFN-8 layout guidance for automotive-grade power rail design.

Technical Context

The MPQ2013AGQ-25-AEC1-Z implements a PMOS-based low-dropout architecture with internal feedback reference of 1.215V, enabling precise 2.5V output via factory-trimmed resistor divider. Its EN pin features asymmetric thresholds (1.32–1.64V rise, 1.1–1.42V fall) for controlled startup and brownout hysteresis.

Thermal protection activates at 150°C junction temperature with 20°C hysteresis, and current limiting caps peak output at 270mA while sustaining 150mA continuous under worst-case thermal resistance (θ_JA = 48°C/W). It operates across −40°C to +125°C ambient with junction up to +150°C.

Key Specifications

Pinout & Package

MPQ2013AGQ-25-AEC1-Z uses a thermally enhanced QFN-8 (3mm×3mm, 0.65mm pitch) package with exposed thermal pad. The pad and GND pin must be soldered to a solid ground plane for θ_JA = 48°C/W and reliable 150mA operation.

FAQ

What is the maximum allowable input voltage for MPQ2013AGQ-25-AEC1-Z?

The absolute maximum input voltage is +42V, but the recommended operating range is 2.5V to 40V. Operation above 40V risks exceeding absolute maximum ratings and may trigger internal protection or cause permanent damage. Automotive load dump pulses must be clamped externally if exceeding 40V.

Does MPQ2013AGQ-25-AEC1-Z require an external feedback resistor network?

No. As a fixed 2.5V output variant, the FB pin is internally connected to the precision voltage divider and may be left unconnected. External resistors are only required for adjustable-output versions or when fine-tuning the output voltage of fixed variants using the internal FB node.

How does the EN pin behave during automotive battery voltage transients?

The EN pin has asymmetric thresholds: rising enable occurs at 1.32–1.64V, and falling disable at 1.1–1.42V. This 200–300mV hysteresis prevents oscillation during slow battery recovery after cranking, ensuring clean startup without repeated enable/disable cycling.

Can MPQ2013AGQ-25-AEC1-Z operate with a 0.47µF output capacitor?

Yes. The device is stable with ceramic output capacitors as low as 0.47µF (X5R/X7R dielectric), eliminating ESR requirements and enabling use of compact, low-cost MLCCs. Larger values (e.g., 4.7µF) improve load transient response but are not mandatory for stability.

What thermal derating applies at 85°C ambient temperature?

With θ_JA = 48°C/W, the maximum power dissipation at 85°C ambient is (150°C − 85°C)/48°C/W = 1.35W. At 2.5V output and 150mA load, power dissipation is 0.1125W - well within limit. Derating only becomes relevant above ~200mA or with poor PCB copper area.

Is reverse voltage protection integrated into MPQ2013AGQ-25-AEC1-Z?

No. The internal PMOS pass device includes a body diode that conducts from OUT to IN if V_OUT > V_IN, potentially causing destructive reverse current. An external Schottky diode in series with the IN pin is required in backup-battery or dual-supply configurations to prevent this failure mode.

How is AEC-Q100 Grade 1 qualification verified for this part?

MPQ2013AGQ-25-AEC1-Z undergoes full AEC-Q100 stress testing including HTOL (1000h at 150°C), TC (1000 cycles −40°C to +125°C), UHAST, and ESD (2kV HBM), with all parameters meeting Grade 1 limits. Test reports and certificate of compliance are available upon request from MPS or Aetrix Electronics.
