Monolithic Power Systems Inc. MPQ2013AGQ-5-P

Overview

MPQ2013AGQ-5-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-P datasheet, MPQ2013AGQ-5-P pinout, MPQ2013AGQ-5-P application, or MPQ2013AGQ-5-P 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.

Technical Context

The MPQ2013AGQ-5-P uses a PMOS pass transistor architecture enabling low dropout and reverse-voltage robustness when paired with external input diode protection. Its internal feedback reference is fixed at 1.215V, with output regulation achieved via precision resistor divider scaling - though the -5-P variant integrates factory-trimmed resistors for 5V output without external components.

Control logic includes integrated current limiting (160–400mA trip range), thermal shutdown with 20°C hysteresis, and EN-driven enable/disable sequencing. The device remains stable with minimal 0.47μF X5R/X7R ceramic output capacitance, eliminating need for electrolytic or tantalum alternatives.

Key Specifications

Pinout & Package

MPQ2013AGQ-5-P is housed in a thermally enhanced QFN-8 (3mm×3mm) package with exposed thermal pad. Pin 1 is marked by a dot or chamfered corner; the exposed pad (Pin 4) must be soldered to a dedicated ground plane for thermal and electrical integrity.

FAQ

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

The absolute maximum input voltage is +42V, but the recommended operating range is 2.5V to 40V. Operation above 40V risks exceeding safe power dissipation limits even at light loads, especially in high ambient temperatures. Sustained exposure to 42V may trigger thermal shutdown or reduce long-term reliability.

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

No. The MPQ2013AGQ-5-P is a fixed 5V output variant with internal resistor divider; the FB pin is internally connected and must be left floating. External resistors are only needed for adjustable-output versions (e.g., MPQ2013AGQ) or to fine-tune fixed outputs using the internal divider as a base.

How does the EN pin behave during power-up and shutdown?

The EN pin has asymmetric thresholds: rising enable occurs at 1.32–1.64V, while falling disable occurs at 1.1–1.42V, providing 200–300mV hysteresis. This prevents oscillation near the threshold and ensures clean, bounce-free sequencing. Pulling EN below 1.1V fully disables the regulator, reducing supply current to <3µA.

Can MPQ2013AGQ-5-P operate with a 0.47μF output capacitor only?

Yes - the device is explicitly characterized and guaranteed stable with ≥0.47μF X5R or X7R ceramic capacitors. Larger values (e.g., 4.7μF) improve load transient response and PSRR, but the minimum 0.47μF enables compact, low-cost designs where space or cost prohibits larger caps.

Is reverse voltage protection built-in on the input pin?

No. The internal PMOS pass transistor includes a body diode that conducts from OUT to IN if VOUT > VIN, potentially causing destructive reverse current. An external Schottky diode (cathode to IN, anode to GND) is required in backup-battery or dual-supply configurations to block this path.

What is the thermal resistance (θJA) of the QFN-8 package?

The junction-to-ambient thermal resistance is 48°C/W on a standard 4-layer JEDEC PCB per JESD51-7. With 2.08W max power dissipation and 150°C max junction temperature, this allows ~100°C ambient rise at full 150mA load - requiring adequate copper area and thermal vias beneath the exposed pad for reliable operation.
