Monolithic Power Systems Inc. MPQ2013AGJE-C672-Z

Overview

MPQ2013AGJE-C672-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified 40V input, 150mA low-dropout linear regulator in QFN-6 (2mm×2mm) package with fixed 3.3V output, ±4% accuracy, 3.3µA quiescent current, and 620mV dropout at full load-designed for automotive body control modules requiring stable low-power bias under wide battery voltage transients.

For engineers reviewing the MPQ2013AGJE-C672-Z datasheet, MPQ2013AGJE-C672-Z pinout, MPQ2013AGJE-C672-Z application, or MPQ2013AGJE-C672-Z equivalent, this part supports ultra-low-power microcontroller supply, battery-backed sensor nodes, and automotive infotainment subsystems where input voltage may range from 2.5V to 40V and thermal robustness up to +150°C junction temperature is required.

Technical Context

The MPQ2013AGJE-C672-Z implements a PMOS pass transistor architecture enabling true low-dropout operation down to 620mV at 150mA while maintaining stability with ≥0.47μF ceramic output capacitance. Its internal feedback reference is trimmed to 1.215V, and the fixed 3.3V output version integrates an internal resistor divider calibrated for ±4% output accuracy over –40°C to +125°C ambient.

EN pin logic control enables precise system-level power sequencing with 1.26V falling threshold and <0.1µA input leakage; thermal shutdown activates at 150°C with 20°C hysteresis, and current limiting caps peak output at 270mA to protect against sustained overload without external components.

Key Specifications

Pinout & Package

FAQ

What is the minimum input voltage required for regulation at 3.3V output?

The MPQ2013AGJE-C672-Z maintains regulation down to VIN = VOUT + VDROPOUT. With 620mV typical dropout at 150mA, minimum input is 3.92V. At lighter loads (e.g., 1mA), dropout drops to ~100mV, allowing regulation from 3.4V-critical for low-battery brownout recovery in automotive systems.

Can the FB pin be used to adjust the output voltage on this fixed-version part?

No-the MPQ2013AGJE-C672-Z is a factory-trimmed fixed 3.3V variant with internal feedback divider. The FB pin is internally connected and must remain floating; connecting external resistors will disrupt regulation and void accuracy guarantees. Use adjustable versions (e.g., MPQ2013AGJE) for programmable outputs.

How is thermal performance affected if the exposed pad is not soldered to ground?

Without soldering the exposed thermal pad to a ≥100mm² copper pour, θJA degrades from 80°C/W to >120°C/W. At 150mA load and 25°C ambient, junction temperature rises from ~75°C to >115°C-triggering thermal shutdown intermittently. Full thermal pad connection is mandatory for reliable 150mA operation.

Does this part support reverse voltage protection on the output?

No-MPQ2013AGJE-C672-Z contains a PMOS pass device with an inherent body diode that conducts from OUT to IN if VOUT > VIN. In backup-battery scenarios, this causes uncontrolled reverse current. An external Schottky diode (e.g., DFLS160) in series with IN is required to block reverse conduction and prevent damage.

What is the startup response time and how does it affect system reset timing?

Startup response time is 3ms (to 90% of 3.3V) with 6.8μF output capacitor. This ensures clean power-up for MCUs with 10ms–100ms reset timeout windows. For faster wake-up in low-power modes, reduce COUT to 1μF (response ~1ms), verified stable per datasheet Figure 10.

Is the EN pin compatible with 1.8V logic microcontrollers?

Yes-the EN pin has 1.26V falling threshold and 1.48V rising threshold, making it compatible with 1.8V GPIOs. A 1.8V logic HIGH exceeds the 1.48V ENTH_R, ensuring reliable enable; a 0V logic LOW falls below 1.26V ENTH_F, guaranteeing full shutdown with <3µA supply current.

How does load regulation impact ADC reference stability in precision sensor applications?

Load regulation is 0.020%/mA for the QFN-6 3.3V variant-translating to ±3.3mV output shift over 0–150mA load change. When powering a 16-bit ADC with 3.3V reference, this introduces ≤0.05% full-scale error, well within typical industrial sensor accuracy budgets without additional post-regulation filtering.
