Monolithic Power Systems Inc. MPQ2013AGQ-5-AEC1-P

Overview

MPQ2013AGQ-5-AEC1-P from Monolithic Power Systems is a 40V-input, 5V-output AEC-Q100 Grade 1 qualified linear regulator in QFN-8 (3mm×3mm) package, delivering up to 150mA with 620mV dropout at full load and 3.3µA quiescent current. It operates across –40°C to +150°C junction temperature and supports automotive body control modules, battery-powered telematics, and ultra-low-power microcontroller power rails.

For engineers reviewing the MPQ2013AGQ-5-AEC1-P datasheet, MPQ2013AGQ-5-AEC1-P pinout, MPQ2013AGQ-5-AEC1-P application, or MPQ2013AGQ-5-AEC1-P equivalent, this device offers verified AEC-Q100 qualification, fixed 5V output with ±2% accuracy, thermal shutdown, current limiting, and compatibility with low-ESR ceramic capacitors ≥0.47μF - critical for automotive ECU and ADAS subsystem design.

Technical Context

The MPQ2013AGQ-5-AEC1-P uses a PMOS pass transistor architecture enabling low dropout operation and reverse-voltage protection awareness. Its internal reference is trimmed to 1.215V at the FB pin, and regulation is maintained via error amplifier feedback with integrated overtemperature and overload protection logic.

EN pin control provides precise enable/disable sequencing with 1.26V falling threshold and 1.48V rising threshold; shutdown reduces supply current to ≤9µA. The device sustains stable regulation across 2.5V–40V input while maintaining ±2% output voltage accuracy over temperature and line/load conditions.

FAQ

What is the maximum allowable input voltage for MPQ2013AGQ-5-AEC1-P?

The absolute maximum input voltage is +42V, but the recommended operating range is 2.5V to 40V. Exceeding 42V risks permanent damage to the internal PMOS pass transistor and ESD protection structures. For automotive load-dump immunity, external TVS clamping is advised when transient spikes exceed 40V.

Does MPQ2013AGQ-5-AEC1-P require an external feedback resistor network?

No - the "-5" suffix denotes a fixed 5V output version. The FB pin is internally connected to the reference divider and must be left unconnected. External resistors are only required for adjustable versions (e.g., MPQ2013AGQ) or when fine-tuning fixed outputs using the internal divider's known R1_IN/R2_IN values.

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

The EN pin has asymmetric thresholds: rising enable occurs at 1.48V (typ), falling disable at 1.26V (typ), providing 220mV hysteresis. This prevents oscillation during slow-rising or noisy supply ramps. When EN is pulled below 1.26V, the IC enters shutdown with ≤9µA supply current and disables the pass transistor.

Can MPQ2013AGQ-5-AEC1-P operate with ceramic output capacitors smaller than 1µF?

Yes - the datasheet guarantees stability with ceramic capacitors ≥0.47µF (X5R/X7R dielectric). Using 0.47µF–1µF saves board space and cost versus traditional 10µF tantalum solutions, while maintaining phase margin >45° across temperature and load conditions.

What thermal derating applies when using MPQ2013AGQ-5-AEC1-P in a 4-layer PCB?

With θJA = 48°C/W (JEDEC JESD51-7, 4-layer board), maximum continuous power dissipation at 25°C ambient is 2.08W. At 85°C ambient, usable power drops to ~1.35W. Derating follows PD(MAX) = (150°C − TA)/48°C/W; thermal shutdown activates if junction exceeds 150°C.

Is reverse-voltage protection built-in, and what happens if VOUT > VIN?

No internal reverse-voltage protection exists. The PMOS pass transistor's intrinsic body diode conducts from OUT to IN when VOUT > VIN, causing uncontrolled current flow. An external Schottky diode (cathode to IN, anode to GND) is mandatory in backup-battery or dual-supply configurations to prevent damage.
