Monolithic Power Systems Inc. MPQ2013AGG-5-P

Overview

MPQ2013AGG-5-P from Monolithic Power Systems is a 40V-input, 150mA AEC-Q100 Grade 1 qualified low-quiescent-current linear regulator in QFN-6 (2mm×2mm) package, delivering fixed 5.0V output with ±4% accuracy at 150mA load and 600–1100mV dropout. It operates from −40°C to +125°C ambient, supports battery-powered automotive microcontrollers, and features thermal shutdown and current limiting.

For engineers reviewing the MPQ2013AGG-5-P datasheet, MPQ2013AGG-5-P pinout, MPQ2013AGG-5-P application, or MPQ2013AGG-5-P equivalent, key selection criteria include its 3.3µA quiescent current at light load, 2.5V–40V input range, compatibility with ≥0.47μF ceramic output capacitors, and AEC-Q100 qualification for under-hood automotive use.

Technical Context

The MPQ2013AGG-5-P uses a PMOS pass transistor architecture enabling low dropout and reverse-voltage robustness when paired with external protection diodes. Its internal feedback reference is trimmed to 1.215V, and the EN pin provides precise enable control with 1.26V falling threshold and 0.1µA input current.

Thermal regulation is implemented via junction-sensing with 150°C shutdown and 20°C hysteresis. Current limiting is specified at 160–400mA depending on VIN and VOUT, exceeding the 150mA continuous rating to support transient loads without latch-off.

Key Specifications

Pinout & Package

MPQ2013AGG-5-P is housed in a thermally enhanced QFN-6 (2mm × 2mm) package with exposed thermal pad. The 6-pin layout prioritizes compact routing and thermal dissipation: IN and OUT are placed diagonally opposite GND and EN, while FB is omitted (fixed-output version) and NC pins provide flexibility for grounding or thermal enhancement.

FAQ

What is the maximum input voltage the MPQ2013AGG-5-P can withstand?

The absolute maximum input voltage is +42V, but the recommended operating range is 2.5V to 40V. Sustained operation above 40V risks permanent damage, and transient spikes beyond 42V-even briefly-may exceed internal junction limits. Designers should implement clamping (e.g., TVS diode) if load-dump events exceed 40V.

Does the MPQ2013AGG-5-P require an external feedback resistor network?

No. As a fixed-output variant, the MPQ2013AGG-5-P integrates the feedback divider internally to deliver 5.0V. Pin 4 (FB) is not connected and may be left floating or grounded for mechanical stability; no external resistors are needed for basic operation.

How does thermal performance differ between QFN-6 and QFN-8 packages?

The QFN-6 (MPQ2013AGG-5-P) has θJA = 80°C/W and max power dissipation of 1.25W at +25°C ambient, while the QFN-8 (MPQ2013AGQ-5) achieves θJA = 48°C/W and 2.08W. In practice, the QFN-8 sustains full 150mA output at +105°C ambient, whereas the QFN-6 requires derating above +85°C ambient.

Can the MPQ2013AGG-5-P be used without an input capacitor?

No. An input ceramic capacitor (1µF–10µF, X5R/X7R) is mandatory between IN and GND to suppress high-frequency noise and prevent oscillation. Omitting it causes instability, increased output ripple, and potential failure during line transients-especially critical in automotive 12V systems with alternator noise.

Is reverse-voltage protection built-in?

No. The internal PMOS pass transistor includes a body diode that conducts from OUT to IN if VOUT > VIN (e.g., during backup battery hold-up). This uncontrolled current can destroy the device. An external Schottky diode (cathode to IN, anode to GND) or ideal diode controller is required for reverse-polarity or backup-battery scenarios.

What is the EN pin's behavior during power-up?

The EN pin has hysteresis: rising threshold is 1.48V (typ), falling is 1.26V (typ). When tied directly to IN, the regulator starts only after VIN exceeds ~1.5V-preventing brown-out operation. For controlled sequencing, drive EN with a dedicated supervisor or RC delay to ensure upstream rails stabilize first.

How does output voltage accuracy vary with load and temperature?

For MPQ2013AGG-5-P, output is specified as 4.8V–5.2V (±4%) over full load (0–150mA) and temperature (−40°C to +125°C). At 25°C and 0mA, tolerance tightens to 4.925V–5.075V (±1.5%). Load regulation contributes ≤0.012%/mA, meaning <1.8mV shift from no-load to full-load at fixed temperature.
