Monolithic Power Systems Inc. MPQ2013AGG-33-AEC1-P

Overview

MPQ2013AGG-33-AEC1-P from Monolithic Power Systems is a 40V-input, 3.3V fixed-output linear regulator in QFN-6 (2mm×2mm) package, AEC-Q100 Grade 1 qualified for automotive use. It delivers up to 150mA output current with 3.3µA quiescent current, 620mV dropout at full load, ±4% output voltage accuracy, and operates from −40°C to +150°C junction temperature - enabling reliable power for engine control units and body electronics.

For engineers reviewing the MPQ2013AGG-33-AEC1-P datasheet, MPQ2013AGG-33-AEC1-P pinout, MPQ2013AGG-33-AEC1-P application, or MPQ2013AGG-33-AEC1-P equivalent, key selection criteria include its ultra-low IQ for always-on systems, wide 2.5V–40V input range accommodating battery transients, integrated thermal shutdown and current limiting, and AEC-Q100 qualification for under-hood deployment.

Technical Context

The MPQ2013AGG-33-AEC1-P uses a PMOS pass transistor architecture to achieve low dropout and high input voltage tolerance. Its feedback loop regulates output by comparing FB pin voltage (1.215V nominal) against an internal reference, with internal resistor divider setting fixed 3.3V output.

EN pin logic control enables precise system-level power sequencing, with 1.26V falling threshold and 1.48V rising threshold. Thermal shutdown activates at 150°C with 20°C hysteresis, and current limiting trips at 160–400mA depending on VIN and VOUT conditions.

Key Specifications

Pinout & Package

MPQ2013AGG-33-AEC1-P is housed in a thermally enhanced QFN-6 (2mm×2mm) package with exposed pad. The package supports reflow soldering per JEDEC MO-229 VCCC and requires connection of both Pin 3 (GND) and the exposed pad to the same PCB ground plane for thermal and electrical integrity.

FAQ

What is the maximum allowable input voltage for MPQ2013AGG-33-AEC1-P?

The absolute maximum input voltage is +42V, but the recommended operating range is 2.5V to 40V. Operation above 40V risks permanent damage even for brief transients unless explicitly protected by external clamping circuits per ISO 7637-2 standards.

Can MPQ2013AGG-33-AEC1-P be used without an external output capacitor?

No. A minimum 0.47µF X5R or X7R ceramic capacitor must be placed directly at the OUT pin. Omitting it causes instability and oscillation due to insufficient phase margin in the internal control loop - verified in bench testing per datasheet Figure 10.

How does the EN pin behave during power-up sequences?

EN has 1.48V rising threshold and 1.26V falling threshold with 200mV hysteresis. When tied directly to IN, the device powers up automatically once VIN exceeds ~2.8V. For controlled sequencing, drive EN with a dedicated supervisor IC or RC delay network.

Is the exposed thermal pad electrically isolated?

No. The exposed pad is internally connected to GND and must be soldered to a PCB copper pour tied to the same ground net as Pin 3 (GND). Failure to do so degrades thermal resistance by >40% and risks thermal shutdown under 100mA load.

What is the output voltage accuracy over temperature and load?

For MPQ2013AGG-33-AEC1-P, output voltage is 3.3V ±4% over −40°C to +125°C ambient and 0–150mA load. At +25°C and zero load, accuracy tightens to ±3.3% (3.251V to 3.349V), as specified in Electrical Characteristics Table on page 6.

Does MPQ2013AGG-33-AEC1-P support reverse voltage protection?

No. The internal PMOS pass transistor includes a body diode that conducts from OUT to IN if VOUT > VIN. In backup-battery or dual-supply scenarios, an external Schottky diode must be added in series with the IN pin to prevent destructive reverse current.

How is thermal performance affected by PCB layout?

Thermal resistance θJA is 80°C/W on standard 4-layer board per JESD51-7. Reducing θJA requires ≥100mm² exposed pad copper area with ≥4 thermal vias (0.3mm diameter) to inner ground planes. Without this, junction temperature rises >30°C at 150mA, triggering thermal shutdown.
