Monolithic Power Systems Inc. MP2013GQ-33-Z

Overview

MP2013GQ-33-Z from Monolithic Power Systems is a fixed-output 3.3V, 150mA low-dropout linear regulator with 2.5V–40V input range, 3.2µA quiescent current, and 740mV dropout at full load - designed for ultra-low-power microcontrollers in battery-powered industrial sensors and automotive body electronics.

For engineers reviewing the MP2013GQ-33-Z datasheet, MP2013GQ-33-Z pinout, MP2013GQ-33-Z application, or MP2013GQ-33-Z equivalent, this page delivers verified package mapping (QFN8-3×3mm), thermal shutdown behavior, FB pin voltage accuracy (±2%), output stability with ≥0.47µF ceramic capacitors, and real-world load regulation performance (0.005–0.01%/mA).

Technical Context

The MP2013GQ-33-Z implements a PMOS pass transistor architecture enabling operation down to 2.5V input while maintaining regulation up to 40V. Its internal feedback reference is trimmed to 1.215V ±2%, enabling precise 3.3V output via integrated resistor divider (R1_IN = 1.72MΩ, R2_IN = 1MΩ).

Thermal protection activates at 150°C with 20°C hysteresis, and current limiting triggers at 180–400mA depending on junction temperature. The device operates across –40°C to +125°C junction range and requires GND connection to both pin 3/6/7 and the exposed thermal pad for safe power dissipation (θJA = 48°C/W).

Key Specifications

Pinout & Package

MP2013GQ-33-Z uses a QFN8 (3mm × 3mm) package with wettable flank leads and an exposed thermal pad on the bottom that must be soldered to a dedicated GND copper area for thermal and electrical integrity.

FAQ

What is the maximum continuous output current for MP2013GQ-33-Z?

The MP2013GQ-33-Z is specified for 150mA continuous output current. Its internal current limit ranges from 180mA to 400mA depending on junction temperature, but sustained operation above 150mA requires careful thermal design due to its 48°C/W θJA in QFN8 package and 2.08W max power dissipation at 25°C ambient.

Can MP2013GQ-33-Z operate with a 2.7V input?

Yes - MP2013GQ-33-Z supports inputs as low as 2.5V. At 2.7V input, it delivers 3.3V output only if the dropout condition is met (i.e., V_IN ≥ V_OUT + V_DROPOUT). Since V_DROPOUT is 740mV at 150mA, 2.7V input cannot sustain 3.3V output at any significant load; it is viable only for very light loads (<1mA) where dropout drops below 400mV.

Is an external feedforward capacitor required for stability?

No - MP2013GQ-33-Z is stable with only a ≥0.47µF ceramic output capacitor. A 22nF feedforward capacitor across the upper FB resistor improves transient response and reduces output noise but is optional and not required for basic regulation stability.

How should the exposed thermal pad be connected?

The exposed pad on the bottom of the QFN8 package must be soldered to a dedicated GND copper pour with ≥4 thermal vias (0.3mm diameter) connecting to inner-layer or backside GND planes. This ensures both electrical grounding and thermal dissipation - failure to do so risks thermal shutdown at currents above ~80mA.

Does MP2013GQ-33-Z include reverse-voltage protection?

No - the internal PMOS pass transistor has a body diode that conducts from OUT to IN if V_OUT > V_IN. In configurations with backup batteries or hot-swap scenarios, an external Schottky diode (e.g., 1N5819) must be placed in series with the IN1 pin to prevent destructive reverse current.

What is the FB pin voltage accuracy and how does it affect output tolerance?

The FB pin is regulated to 1.215V ±2% (1.191V–1.239V). For the MP2013GQ-33-Z fixed version, this reference sets the 3.3V output via an internal 1.72MΩ/1MΩ resistor divider. Output accuracy is therefore determined by both FB reference tolerance and resistor ratio matching, resulting in total ±2% output error over temperature and line conditions.

Can MP2013GQ-33-Z replace MP2013GG-33-Z in existing designs?

Yes - both share identical electrical specifications and 3.3V output, but MP2013GQ-33-Z uses QFN8 (3mm×3mm) while MP2013GG-33-Z uses QFN6 (2mm×2mm). Pin compatibility is not maintained: QFN6 has 6 pins (IN1, IN2, GND, FB, OUT, NC); QFN8 adds two NC pins and relocates GND/FB/OUT. PCB layout and footprint must be revised.
