Monolithic Power Systems Inc. MP2013AGG-Z

Overview

MP2013AGG-Z from Monolithic Power Systems is a 40V-input, 150mA low-quiescent-current linear regulator in QFN6 (2mm×2mm) package, delivering fixed 3.3V output with ±2% accuracy and 620mV dropout at full load. It operates across –40°C to +125°C junction temperature and supports ultra-low-power microcontrollers and battery-powered industrial sensors.

For engineers reviewing the MP2013AGG-Z datasheet, MP2013AGG-Z pinout, MP2013AGG-Z application, or MP2013AGG-Z equivalent, key selection criteria include its 3.3µA quiescent current, compatibility with ≥0.47μF ceramic output capacitors, thermal shutdown behavior at 150°C, and EN pin logic-level enable control for power sequencing.

Technical Context

The MP2013AGG-Z implements a PMOS pass transistor architecture enabling low-dropout operation and reverse-voltage protection awareness via external diode recommendation. Its internal feedback reference is trimmed to 1.215V, supporting both fixed-output (3.3V) and adjustable configurations through FB pin routing.

It integrates overcurrent limiting (270mA peak), thermal shutdown with 20°C hysteresis, and EN-controlled shutdown reducing supply current to <3µA. Input UVLO is programmable via external resistor divider on EN, with rising/falling thresholds of 1.48V/1.26V respectively.

FAQ

What is the minimum input voltage required for MP2013AGG-Z to regulate 3.3V output?

The MP2013AGG-Z requires VIN ≥ (VOUT + VDROPOUT) = 3.3V + 0.62V = 3.92V at 150mA load. At lighter loads, dropout decreases-e.g., 350mV at 10mA-so regulation begins as low as 3.65V under light conditions. Absolute minimum specified VIN is 2.5V, but regulation is not guaranteed below 3.92V at full load.

Can MP2013AGG-Z be used with an input voltage higher than 40V?

No. The absolute maximum input voltage is +42V, but continuous operation above 40V violates the recommended operating condition and risks permanent damage. Transient spikes beyond 40V must be clamped externally-for example, with a TVS diode rated for ≤40V working voltage-to ensure long-term reliability.

Is the FB pin internally connected in the MP2013AGG-Z fixed-output variant?

Yes. In the MP2013AGG-Z (3.3V fixed version), the FB pin is internally tied to a precision resistor divider that sets VOUT = 3.3V. It may be left unconnected (floating) in standard operation. External feedback is only required for adjustable versions like MP2013AGG.

Does MP2013AGG-Z require an input capacitor, and what type is recommended?

Yes. A ceramic capacitor of 1µF–10µF (X5R or X7R dielectric) must be placed between IN and GND, as close as possible to the IN pin. This stabilizes input impedance, filters high-frequency noise, and improves line transient response-omitting it risks instability or erratic enable behavior during input voltage steps.

How does thermal shutdown behave during overload, and can it be manually reset?

When junction temperature reaches 150°C, thermal shutdown disables the pass transistor, dropping output to 0V and reducing quiescent current to <3µA. Recovery occurs automatically after temperature falls by ≥20°C (hysteresis). No manual reset is needed-the device resumes regulation once cooled, provided EN remains high.

What is the purpose of the exposed thermal pad on the QFN6 package?

The exposed pad is electrically connected to GND and serves as the primary thermal conduction path from the die to the PCB. It must be soldered to a solid copper pour tied to the system ground plane. Omitting this connection increases θJA by ~30°C/W, risking premature thermal shutdown even at moderate loads.

Can MP2013AGG-Z safely drive a 150mA load continuously at 85°C ambient temperature?

Yes-if PCB layout provides adequate thermal relief. With θJA = 80°C/W (QFN6), power dissipation at 150mA and 6V dropout (0.62V × 0.15A ≈ 93mW) yields ΔT = 93mW × 80°C/W = 7.4°C rise. Junction temperature would be 85°C + 7.4°C = 92.4°C-well below the 125°C max operating TJ and 150°C shutdown threshold.
