Monolithic Power Systems Inc. MPQ2013AGG-5-AEC1-Z

Overview

MPQ2013AGG-5-AEC1-Z from Monolithic Power Systems is a 40V-input, 150mA AEC-Q100 Grade 1 qualified low-quiescent-current linear regulator in QFN-6 (2mm×2mm) package, delivering fixed 5.0V output with ±4% accuracy, 3.3µA quiescent current, and 620mV dropout at 150mA - designed for automotive body control modules, battery-powered telematics, and ultra-low-power microcontroller power rails.

For engineers reviewing the MPQ2013AGG-5-AEC1-Z datasheet, MPQ2013AGG-5-AEC1-Z pinout, MPQ2013AGG-5-AEC1-Z application, or MPQ2013AGG-5-AEC1-Z equivalent, this page provides verified package mapping, thermal shutdown behavior, EN threshold validation, FB voltage tolerance, and AEC-Q100 Grade 1 qualification evidence - all confirmed against Monolithic Power's Rev. 1.1 datasheet and ordering documentation.

Technical Context

The MPQ2013AGG-5-AEC1-Z implements a PMOS pass transistor architecture enabling operation down to 2.5V input while maintaining regulation up to 40V, with internal feedback reference fixed at 1.215V for the 5V variant. Its EN pin features asymmetric thresholds (1.32–1.64V rising, 1.1–1.42V falling) enabling precise UVLO configuration via external resistor dividers.

Thermal protection activates at 150°C junction temperature with 20°C hysteresis, and current limiting engages at 160–400mA depending on VIN and VOUT conditions. The device achieves stability with ≥0.47μF ceramic output capacitance and supports reverse-voltage protection via external input diode due to inherent body-diode conduction path.

Key Specifications

Pinout & Package

MPQ2013AGG-5-AEC1-Z uses the QFN-6 (2mm × 2mm) thermally enhanced package with exposed pad. Pin 1 is marked by a dot or chamfered corner; the exposed pad must be soldered to a dedicated ground plane for thermal and electrical integrity.

FAQ

What is the maximum allowable input voltage for MPQ2013AGG-5-AEC1-Z?

The absolute maximum input voltage is +42V, but the recommended operating range is 2.5V to 40V per the datasheet. Operation above 40V risks exceeding safe operating area limits and may trigger overvoltage stress failure, especially during transient events like load dump. Designers should implement clamping or filtering if system-level transients exceed 40V.

Can MPQ2013AGG-5-AEC1-Z be used with an output capacitor smaller than 0.47μF?

No - the device requires ≥0.47μF ceramic output capacitance for guaranteed stability across temperature and load conditions. Using smaller values may cause oscillation or poor transient response, particularly under step-load changes. X5R or X7R dielectrics are mandatory; Y5V or Z5U types exhibit excessive capacitance drift and are not supported.

How does the EN pin behave during power-up and brownout conditions?

The EN pin has asymmetric thresholds: rising enable occurs at 1.32–1.64V, while disable occurs at 1.1–1.42V, providing 0.22V–0.24V hysteresis. This prevents chatter during slow-rising or noisy supply ramps. For controlled startup, tie EN to IN through a resistor divider to set custom UVLO points - e.g., 4.5V turn-on using R3=2MΩ and R4=778kΩ.

Is the exposed thermal pad electrically isolated in the QFN-6 package?

No - the exposed pad is internally connected to GND and must be soldered to a solid copper ground plane. It serves as both the primary thermal path and electrical return. Failure to connect it results in elevated junction temperature, premature thermal shutdown, and potential parametric shift in output voltage accuracy and dropout performance.

Does MPQ2013AGG-5-AEC1-Z support reverse-voltage protection natively?

No - the internal PMOS pass transistor includes a body diode that conducts from OUT to IN when V_OUT > V_IN, potentially causing destructive reverse current. An external Schottky diode (cathode to IN, anode to GND) or ideal diode controller is required in backup-battery or dual-supply configurations to prevent damage.

What is the output voltage accuracy over temperature for this part?

For MPQ2013AGG-5-AEC1-Z (QFN-6), output voltage accuracy is ±4% over the full operating temperature range of −40°C to +125°C ambient. At +25°C, typical accuracy tightens to ±2.5% (4.875V to 5.125V), as confirmed by electrical characteristics table entries for V_OUT = 4.8V to 5.2V at I_OUT = 0 and V_IN = 6V.

How does thermal resistance differ between QFN-6 and QFN-8 packages?

The QFN-6 (2mm×2mm) has θ_JA = 80°C/W and θ_JC = 16°C/W, while the QFN-8 (3mm×3mm) offers θ_JA = 48°C/W and θ_JC = 11°C/W. This means the QFN-8 dissipates heat ~1.7× more effectively under identical PCB layout conditions - critical for continuous 150mA loads in high-ambient environments like engine compartments.
