Monolithic Power Systems Inc. MPQ2013AGG-Z

Overview

MPQ2013AGG-Z 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. It delivers stable fixed 3.3V or 5V output (±4% accuracy), features 3.3µA quiescent current, 620mV dropout at 150mA, and operates from −40°C to +150°C junction temperature-designed for automotive body control modules requiring ultra-low standby power.

For engineers reviewing the MPQ2013AGG-Z datasheet, MPQ2013AGG-Z pinout, MPQ2013AGG-Z application, or MPQ2013AGG-Z equivalent, key selection criteria include input voltage range (2.5V–40V), thermal shutdown threshold (150°C), EN pin logic thresholds (1.32V/1.26V), FB reference voltage (1.215V), and compatibility with ≥0.47μF ceramic output capacitors.

Technical Context

The MPQ2013AGG-Z employs a PMOS pass transistor architecture enabling low dropout and reverse-voltage resilience only when externally protected. Its internal bandgap reference and error amplifier regulate output via feedback pin (FB), supporting both fixed-output variants and adjustable configurations using external resistor dividers.

Operation includes precision enable control with hysteresis (EN rising/falling thresholds differ by 0.22V), thermal shutdown with 20°C hysteresis, and current limiting set to 160–400mA depending on output voltage and load condition-ensuring robust fault handling without external circuitry.

Key Specifications

FAQ

What is the maximum allowable input voltage for MPQ2013AGG-Z?

The absolute maximum input voltage is +42V, but recommended operating range is 2.5V to 40V. Exceeding 40V risks violating safe operating area limits during transients, even if duration is short. Designers must ensure transient suppression (e.g., TVS diode) clamps spikes below 42V to prevent permanent damage.

Can MPQ2013AGG-Z be used with a 24V battery system without external protection?

Yes-it accepts up to 40V continuously and withstands 42V absolute maximum, covering standard 24V automotive systems including load dump. However, external reverse-voltage protection (e.g., input Schottky diode) is required if the output may exceed input voltage, as the internal PMOS body diode conducts uncontrolled reverse current.

How does the FB pin function in fixed-output versions of MPQ2013AGG-Z?

In fixed-output variants like MPQ2013AGG-33-Z, the FB pin is internally connected to a precision resistor divider and may be left floating. It is not used for regulation but remains accessible for optional external trimming or monitoring-no external components are needed for nominal operation.

What thermal performance can be expected with the QFN-6 package on a 2-layer PCB?

On a standard 2-layer board with 1oz copper and minimal thermal vias, θJA is ~80°C/W. At 150mA and 12V input (8.7W dissipation), junction temperature rise would be ~696°C-exceeding limits. Real-world designs require ≥4 thermal vias under the exposed pad and a solid ground plane to achieve usable power dissipation (≤1.25W continuous).

Is MPQ2013AGG-Z compatible with ceramic output capacitors smaller than 1μF?

Yes-stability is guaranteed with ≥0.47μF X5R/X7R ceramic capacitors. Smaller values (e.g., 0.56μF) are acceptable and commonly used to minimize board area in space-constrained automotive modules, provided ESR remains <10mΩ and capacitance tolerance accounts for DC bias derating.

Does MPQ2013AGG-Z support power sequencing with other ICs?

Yes-the EN pin provides precise, hysteresis-enabled control (1.32V rise / 1.26V fall) ideal for synchronized startup/shutdown. When paired with a resistor divider on VIN, it enables programmable undervoltage lockout (UVLO), allowing coordinated power-up with microcontrollers or PMICs in multi-rail systems.

What is the output voltage accuracy over temperature for MPQ2013AGG-33-Z?

For MPQ2013AGG-33-Z, output voltage accuracy is ±4% over −40°C to +125°C ambient, with tighter ±3.3% (3.251V–3.349V) at +25°C. This includes initial tolerance, line/load regulation, and thermal drift-verified per AEC-Q100 stress testing protocols.
