Monolithic Power Systems Inc. MPQ2013AGQ-5-Z

Overview

MPQ2013AGQ-5-Z 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-Z datasheet, MPQ2013AGQ-5-Z pinout, MPQ2013AGQ-5-Z application, or MPQ2013AGQ-5-Z equivalent, key selection criteria include its 5V ±2% output accuracy, EN pin logic thresholds (1.32–1.64V rise, 1.1–1.42V fall), thermal shutdown at 150°C, and compatibility with ≥0.47μF ceramic output capacitors without external compensation.

Technical Context

The MPQ2013AGQ-5-Z integrates a PMOS pass transistor with internal feedback reference (1.215V on FB pin) and precision bandgap circuitry to maintain stable 5V output across 2.5V–40V input range. Its low-quiescent-current architecture uses bias current scaling and optimized gate drive to sustain 3.3µA supply current at no load while supporting 150mA continuous output.

Protection features include foldback current limiting (160–400mA trip range), thermal shutdown with 20°C hysteresis, and EN-controlled startup sequencing. The device requires no external compensation and achieves stability with minimal 0.47μF X5R/X7R ceramic output capacitance - enabling compact layout in space-constrained automotive and industrial PCBs.

Key Specifications

Pinout & Package

MPQ2013AGQ-5-Z is housed in a thermally enhanced QFN-8 (3mm×3mm, 0.65mm pitch) package with exposed thermal pad. The package supports ≤2.08W continuous power dissipation at +25°C ambient (θJA = 48°C/W) and requires soldering the exposed pad to a dedicated ground plane for optimal thermal performance.

FAQ

What is the minimum input voltage required for MPQ2013AGQ-5-Z to regulate 5V output?

The MPQ2013AGQ-5-Z requires a minimum input voltage of 5.62V to maintain regulation at 150mA load, based on its 620mV dropout specification. At lighter loads, dropout decreases - e.g., 350mV at 50mA - allowing operation down to ~5.35V. Below 5.62V at full load, output voltage drops linearly with input.

Can MPQ2013AGQ-5-Z be used without an output capacitor?

No. The MPQ2013AGQ-5-Z requires a minimum 0.47μF X5R or X7R ceramic capacitor directly at the OUT pin for stability. Omitting it causes oscillation and potential device failure. Larger values (1–10μF) improve load transient response but are not required for basic stability.

Does MPQ2013AGQ-5-Z include reverse-voltage protection?

No. The MPQ2013AGQ-5-Z lacks internal reverse-voltage protection. Its PMOS pass transistor contains a body diode that conducts from OUT to IN if VOUT > VIN, risking uncontrolled current flow and damage. An external Schottky diode in series with the input is recommended for backup-battery or dual-supply configurations.

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

The EN pin has hysteresis: it turns the regulator ON when voltage rises above 1.32–1.64V and OFF when falling below 1.1–1.42V. This prevents chatter during slow-rising or noisy supply ramps. When tied directly to IN, startup occurs immediately at VIN > 1.64V; for controlled sequencing, drive EN from a supervisor IC or GPIO with clean edges.

What is the thermal performance difference between QFN-6 and QFN-8 packages?

The QFN-8 (3mm×3mm) package has θJA = 48°C/W versus 80°C/W for QFN-6 (2mm×2mm), meaning it dissipates heat 1.7× more effectively. At 150mA and 12V input, QFN-8 junction rise is ~55°C vs. ~92°C for QFN-6 - making QFN-8 essential for high-ambient or high-power automotive applications.

Is MPQ2013AGQ-5-Z compatible with lead-free reflow profiles?

Yes. The MPQ2013AGQ-5-Z is RoHS-compliant and rated for standard lead-free reflow profiles (J-STD-020, peak 260°C). Its QFN-8 package uses matte tin plating and withstands three reflow cycles. Ensure proper thermal pad soldering to maximize heat transfer and reliability.

What tolerance should be applied to the FB pin voltage in design calculations?

The FB pin voltage is specified as 1.191–1.239V over temperature and process variation. For worst-case output accuracy analysis, use 1.191V (min) and 1.239V (max) in resistor-divider calculations. The typical value of 1.215V is valid only at +25°C and should not be used for production margining.
