Monolithic Power Systems Inc. MPQ2013AGQ-33-AEC1-P

Overview

MPQ2013AGQ-33-AEC1-P from Monolithic Power Systems is a 40V-input, 3.3V fixed-output linear regulator delivering up to 150mA with 3.3µA quiescent current, 620mV dropout at full load, ±2% output accuracy (QFN-8), and AEC-Q100 Grade 1 qualification for automotive power rails. It powers ultra-low-power microcontrollers in high-voltage battery systems such as engine control units and body electronics.

For engineers reviewing the MPQ2013AGQ-33-AEC1-P datasheet, MPQ2013AGQ-33-AEC1-P pinout, MPQ2013AGQ-33-AEC1-P application, or MPQ2013AGQ-33-AEC1-P equivalent, key selection criteria include its 2.5–40V input range, thermal shutdown at 150°C, EN pin logic threshold (1.26–1.48V), stable operation with ≥0.47µF ceramic output capacitance, and QFN-8 (3mm×3mm) package compatibility with automotive PCB layouts.

Technical Context

The MPQ2013AGQ-33-AEC1-P employs a PMOS pass transistor architecture enabling low dropout and reverse-voltage resilience via external diode protection. Its internal 1.215V reference feeds an error amplifier that regulates output by adjusting gate drive to maintain fixed 3.3V across load variations from 100µA to 150mA.

EN pin control enables precise system-level power sequencing with 1.26V falling and 1.48V rising thresholds; shutdown reduces supply current to ≤9µA. Thermal shutdown activates at 150°C with 20°C hysteresis, and current limiting caps peak output at 270mA to protect against sustained overloads.

FAQ

What is the maximum allowable input voltage for MPQ2013AGQ-33-AEC1-P?

The absolute maximum input voltage is +42V, but recommended operating range is 2.5V to 40V. Exceeding 42V risks permanent damage to the internal PMOS pass device and reference circuitry, even momentarily during load-dump events. For 42V transient suppression, external TVS clamping is required before the IN pin.

Can MPQ2013AGQ-33-AEC1-P operate with a 0.47µF output capacitor?

Yes - it is specifically characterized and guaranteed stable with ceramic output capacitors as low as 0.47µF (X5R/X7R dielectric). This enables compact designs and eliminates need for bulkier tantalum or aluminum electrolytic capacitors typically required by legacy LDOs.

How does the EN pin function during automotive wake-up sequences?

The EN pin features asymmetric thresholds: rising enable occurs at ≥1.48V, while disable triggers at ≤1.26V, providing 220mV hysteresis. This prevents chatter during slow-rising battery voltages and allows reliable wake-up from sleep states using simple resistor dividers tied to ignition-switched 12V lines.

Is thermal pad connection mandatory for MPQ2013AGQ-33-AEC1-P?

Yes - the exposed thermal pad (Pin 5) must be soldered to a solid copper ground plane with ≥80% solder coverage. Without this, junction temperature rise exceeds specification limits under 150mA load, triggering premature thermal shutdown and reducing long-term reliability in automotive under-hood environments.

What output voltage accuracy is guaranteed over temperature?

For the QFN-8 variant (MPQ2013AGQ-33-AEC1-P), output voltage is guaranteed ±2% over -40°C to +125°C ambient, measured at IOUT = 0mA. At 150mA load and +125°C, deviation remains within ±3.5% due to dropout and load regulation effects, verified per AEC-Q100 stress testing protocols.

Does MPQ2013AGQ-33-AEC1-P include reverse-voltage protection?

No - its internal PMOS pass transistor contains a body diode that conducts from OUT to IN if VOUT > VIN. In backup-battery or dual-supply configurations, this can cause destructive reverse current. An external Schottky diode (cathode to IN, anode to GND) is required to block reverse conduction and protect the IC.

What is the typical startup time from EN assertion to regulated 3.3V output?

Startup time is 1.8ms typical when driving a 10mA load with 6.8µF output capacitance, as specified for the 3.3V fixed version. This ensures rapid power-up for time-critical automotive subsystems such as CAN FD initialization or sensor self-test routines.
