Monolithic Power Systems Inc. MPQ2013AGQ-33-P

Overview

MPQ2013AGQ-33-P from Monolithic Power Systems is a 40V-input, 3.3V fixed-output AEC-Q100 Grade 1 linear regulator in QFN-8 (3mm×3mm) package, delivering up to 150mA with 3.3µA quiescent current and 620mV dropout at full load. It operates across –40°C to +150°C junction temperature and targets ultra-low-power automotive microcontrollers and battery-backed industrial sensors.

For engineers reviewing the MPQ2013AGQ-33-P datasheet, MPQ2013AGQ-33-P pinout, MPQ2013AGQ-33-P application, or MPQ2013AGQ-33-P equivalent, key selection criteria include its AEC-Q100 qualification, ±2% output accuracy, thermal shutdown at 150°C, EN pin logic control, and compatibility with low-ESR ceramic capacitors ≥0.47μF.

Technical Context

The MPQ2013AGQ-33-P uses a PMOS pass transistor architecture enabling low dropout and reverse-voltage protection via external diode. Its internal feedback reference is trimmed to 1.215V, and output regulation is maintained across 2.5V–40V input with line regulation of 0.01–0.05%/V and load regulation of 0.015%/mA.

Control logic integrates EN pin threshold (1.32–1.64V rising, 1.1–1.42V falling), thermal shutdown with 20°C hysteresis, and current limiting peaking at 270mA. Startup response time is 1.8ms into 10mA load with 6.8μF output capacitance.

Key Specifications

Pinout & Package

MPQ2013AGQ-33-P is housed in a thermally enhanced QFN-8 (3mm×3mm) package with exposed thermal pad. Pin 1 is marked by a dot or notch; the exposed pad must be soldered to a dedicated ground plane for optimal thermal performance and electrical stability.

FAQ

What is the maximum continuous output current for MPQ2013AGQ-33-P?

The MPQ2013AGQ-33-P is rated for 150mA continuous output current under specified thermal conditions. Its internal current limit activates at 160–400mA depending on input voltage and temperature, providing short-circuit protection without external components. Derating is required above 85°C ambient due to thermal resistance of 48°C/W.

Can MPQ2013AGQ-33-P operate with input voltage below 3.3V?

No. The minimum input voltage is 2.5V, but the device cannot regulate 3.3V output when VIN falls below the sum of VOUT plus dropout voltage (≥3.92V at 150mA). Below that, output follows input minus dropout, entering dropout mode. For sub-3.3V operation, an adjustable version or different regulator is required.

Is an external feed-forward capacitor required for stability?

No. Stability is guaranteed with ≥0.47μF ceramic output capacitor alone. A 22nF feed-forward capacitor across the top FB resistor improves noise rejection and load transient response but is optional-only needed in high-precision analog or >12-bit ADC applications where output noise must be minimized.

How does the EN pin behave during power-up?

The EN pin has hysteresis: rising threshold is 1.32–1.64V, falling threshold is 1.1–1.42V. When pulled to VIN, startup is automatic and monotonic. During slow-rising input, the regulator enables once EN crosses 1.48V typical, avoiding brown-out oscillation. Shutdown current drops to <3µA when EN is held low.

Does MPQ2013AGQ-33-P require input reverse polarity protection?

The device lacks internal reverse-input protection. If VIN may be reversed (e.g., during servicing), an external series Schottky diode is recommended. However, reverse-voltage protection from OUT to IN is critical-when output is held high while input collapses, the internal PMOS body diode conducts uncontrolled current; an external input diode prevents this failure mode.

What is the purpose of the NC pins (3, 6, 7) in QFN-8?

Pins 3, 6, and 7 are no-connect terminals-internally unconnected and electrically isolated. They may be left floating or tied to GND to enhance thermal conduction from the die through the package sidewalls to the PCB ground plane, improving power dissipation without affecting functionality.

How is output voltage accuracy affected by load and temperature?

For MPQ2013AGQ-33-P, output voltage is guaranteed ±2% over –40°C to +125°C ambient and 0–150mA load. At 25°C and zero load, accuracy tightens to ±0.7% (3.234V–3.366V). Load regulation contributes ≤0.015%/mA, meaning worst-case deviation from no-load to full-load is <2.25mV at 150mA.
