Monolithic Power Systems Inc. MPQ2013AGQ-AEC1-Z

Overview

MPQ2013AGQ-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified 40V input, 150mA low-dropout linear regulator in QFN-8 (3mm×3mm) package with 3.3µA quiescent current, 620mV dropout at 150mA, and ±2% output voltage accuracy. It delivers stable 3.3V output for automotive body control modules requiring ultra-low standby power and high-voltage battery compatibility.

For engineers reviewing the MPQ2013AGQ-AEC1-Z datasheet, MPQ2013AGQ-AEC1-Z pinout, MPQ2013AGQ-AEC1-Z application, or MPQ2013AGQ-AEC1-Z equivalent, key selection criteria include AEC-Q100 qualification, 3.3µA IQ under light load, thermal shutdown at 150°C, EN pin logic threshold (1.32–1.64V), and FB voltage tolerance (±2.0% around 1.215V).

Technical Context

The MPQ2013AGQ-AEC1-Z implements a PMOS pass transistor architecture enabling low dropout operation across its 2.5V–40V input range while maintaining sub-µA shutdown current (<3µA). Its internal bandgap reference and error amplifier regulate output via feedback to the FB pin at 1.215V nominal.

Thermal protection uses a junction-sensing circuit triggering shutdown at 150°C with 20°C hysteresis; overcurrent limiting activates at 160–400mA depending on output voltage configuration. The device supports both fixed 3.3V output (as indicated by "-33" suffix) and adjustable versions using external resistor dividers.

FAQ

What is the maximum continuous output current for MPQ2013AGQ-AEC1-Z?

The MPQ2013AGQ-AEC1-Z is rated for 150mA continuous output current in QFN-8 package at TA ≤ +125°C. Peak current limit is 160–400mA depending on output voltage and thermal conditions. Derating is required above +125°C ambient per θJA = 48°C/W.

Can MPQ2013AGQ-AEC1-Z operate with a 5V input and 3.3V output?

Yes. With VIN = 5V and VOUT = 3.3V, dropout is well within specification (620mV typ). The device delivers full 150mA output with minimal power loss (PLOSS ≈ 0.255W), and thermal rise is manageable with standard 2-layer PCB copper pour.

Is an external feedforward capacitor required for stability?

No. Stability is guaranteed with ≥0.47µF ceramic output capacitor alone. A 22nF feedforward capacitor across the upper FB resistor improves noise rejection and load transient response but is optional-not required for basic regulation.

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 tied directly to IN, the device starts up once VIN exceeds ~1.4V and remains active until VIN drops below ~1.25V, preventing chatter during slow-rising battery inputs.

Does MPQ2013AGQ-AEC1-Z require input reverse polarity protection?

The device contains no internal reverse-voltage protection. If output voltage can exceed input (e.g., backup battery scenario), an external Schottky diode must be placed in series with the IN pin to block reverse current through the PMOS body diode and prevent damage.

What is the FB pin voltage tolerance and how does it affect output accuracy?

The FB pin is regulated to 1.215V ±2.0% (1.191–1.239V). For the fixed 3.3V version, internal resistor divider sets output; ±2% FB tolerance contributes directly to the overall ±2% output voltage accuracy specification across temperature and line conditions.

Is the exposed thermal pad electrically connected to GND?

Yes. Pin 3 (GND) and the exposed thermal pad are internally connected to the same ground net. Both must be soldered to a large PCB ground plane for optimal thermal performance and EMI suppression-failure to do so risks thermal shutdown or reduced lifetime.
