Monolithic Power Systems Inc. MPQ2013AGG-33-P

Overview

MPQ2013AGG-33-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 3.3V output with ±4% accuracy at junction temperatures from –40°C to +150°C. It features 3.3µA quiescent current, 620mV dropout at 150mA, and stable operation with ≥0.47μF ceramic output capacitance - enabling use in automotive body control modules and battery-backed industrial sensors.

For engineers reviewing the MPQ2013AGG-33-P datasheet, MPQ2013AGG-33-P pinout, MPQ2013AGG-33-P application, or MPQ2013AGG-33-P equivalent, key selection criteria include its wide 2.5–40V input range, thermal shutdown at 150°C, EN pin logic threshold (1.32–1.64V), FB voltage (1.215V), and GND pin current (4.4–50µA across load conditions).

Technical Context

The MPQ2013AGG-33-P implements a PMOS pass transistor architecture with internal feedback reference and precision bandgap regulation, enabling stable 3.3V output without external resistors. Its EN pin controls startup/shutdown with hysteresis (1.1–1.42V falling, 1.32–1.64V rising), while thermal shutdown and current limiting (160–400mA) protect against overload and overtemperature faults.

It operates across –40°C to +125°C ambient with junction temperature up to +150°C, supported by QFN-6's 80°C/W θ_JA. The device requires only a single 0.47μF ceramic output capacitor for stability and achieves 58dB PSRR at 100Hz - critical for noise-sensitive analog subsystems in automotive ECUs.

Key Specifications

Pinout & Package

MPQ2013AGG-33-P uses a thermally enhanced QFN-6 (2mm × 2mm) package with exposed thermal pad. Pin 1 is marked by a dot or chamfered corner; the exposed pad must be soldered to a PCB ground plane for thermal and electrical integrity.

FAQ

What is the maximum allowable input voltage for MPQ2013AGG-33-P?

The absolute maximum input voltage is +42V, but the recommended operating range is 2.5V to 40V. Exceeding 40V risks violating safe operating area limits even if within absolute max ratings, especially under high ambient temperature or heavy load conditions where power dissipation increases.

Can MPQ2013AGG-33-P be used with input voltages below 3.3V?

Yes - the minimum input voltage is 2.5V. However, operation below 3.92V (3.3V + 620mV dropout) will result in dropout mode with reduced regulation accuracy and increased sensitivity to load transients. For sub-3.3V inputs, consider a buck-boost or LDO with lower dropout.

Is the exposed thermal pad electrically connected to GND?

Yes - the exposed pad is internally connected to the GND terminal and must be soldered to a PCB ground plane. This connection is mandatory for both thermal performance (reducing θ_JA from 80°C/W to ~40°C/W) and electrical stability, as it forms part of the return path for internal bias currents.

Does MPQ2013AGG-33-P require an external feedback resistor network?

No - the "-33" suffix denotes the fixed 3.3V output version. The FB pin is internally connected to the reference and may be left floating. External resistors are only required for adjustable-output variants (e.g., MPQ2013AGG-AEC1) or when modifying the output voltage of fixed versions using the internal divider.

How does the EN pin behave during power-up?

When EN is tied directly to IN, the device enables automatically once VIN exceeds the rising threshold (1.32–1.64V). No external pull-up is needed. If controlled by a microcontroller, ensure the EN signal reaches >1.32V before VIN stabilizes to avoid brown-out latch-up during ramp-up.

What is the output voltage accuracy over temperature and load?

For MPQ2013AGG-33-P, output voltage is specified as ±4% over –40°C to +125°C ambient and full 0–150mA load range. At +25°C and zero load, accuracy tightens to ±3.4% (3.251V to 3.349V), verified per Electrical Characteristics table on page 6 of the datasheet.

Is reverse voltage protection built-in?

No - the internal PMOS pass device includes a body diode that conducts from OUT to IN if V_OUT > V_IN. In backup-battery or hot-swap scenarios, this can cause destructive reverse current. An external Schottky diode in series with IN is required to block reverse conduction.
