Monolithic Power Systems Inc. MPQ2013DGJE-25-AEC1-P

Overview

MPQ2013DGJE-25-AEC1-P from Monolithic Power Systems is a fixed-output 2.5V, 100mA AEC-Q100 Grade 1 linear regulator with 2.5V–40V input range, 3.3µA quiescent current, 385mV dropout at full load, and ±4% output accuracy. It powers ultra-low-power microcontrollers in automotive body electronics and battery-backed industrial sensors where wide VIN and thermal robustness are critical.

For engineers reviewing the MPQ2013DGJE-25-AEC1-P datasheet, MPQ2013DGJE-25-AEC1-P pinout, MPQ2013DGJE-25-AEC1-P application, or MPQ2013DGJE-25-AEC1-P equivalent, key selection criteria include its TSOT23-4 footprint, -40°C to +150°C junction temperature rating, internal current limiting (120–400mA), thermal shutdown threshold (150°C), and compatibility with ≥0.47μF ceramic output capacitors.

Technical Context

The device uses a P-channel MOSFET pass element with internal feedback control referenced to a 1.215V bandgap voltage at the FB pin. Its UVLO circuit disables regulation below 2.5V VIN to prevent unstable startup, while the integrated thermal shutdown activates at 150°C with 20°C hysteresis for reliable fault recovery.

Operation requires no external compensation: stability is ensured with ≥0.47μF X5R/X7R ceramic output capacitance. The fixed 2.5V version internally connects the FB node to the output divider; the pin remains functional for optional external adjustment but may be left floating per datasheet guidance.

FAQ

What is the minimum input voltage required for regulation at 2.5V output?

The MPQ2013DGJE-25-AEC1-P maintains regulation down to 2.5V input, as specified in the absolute maximum ratings and operating conditions. At 100mA load, the dropout voltage is 385mV typ., so VIN must exceed 2.885V for stable 2.5V output. Below 2.5V VIN, the device enters undervoltage lockout and disables output.

Can the FB pin be left unconnected in the fixed 2.5V version?

Yes-the FB pin may be left floating in the MPQ2013DGJE-25-AEC1-P fixed-output configuration. The internal resistor divider sets VOUT to 2.5V; no external components are required. Floating FB introduces no instability or leakage concerns, as confirmed in the datasheet's PIN FUNCTIONS section.

Does this regulator require an input capacitor, and what value is recommended?

Yes-an input capacitor is mandatory. The datasheet specifies a 1µF to 10µF X5R or X7R ceramic capacitor placed directly between the IN pin and GND. A 1µF unit suffices for basic stability; larger values (e.g., 4.7µF) improve line transient response and reduce input ripple coupling.

How does thermal shutdown behave during sustained overload?

When junction temperature reaches 150°C, thermal shutdown disables the pass transistor. After cooldown of ≥20°C (hysteresis), the device automatically resumes regulation. During sustained overload, this results in duty-cycled operation-verified in typical characteristics plots showing repetitive shutdown/restart waveforms under short-circuit conditions.

Is reverse-voltage protection built-in, or is external circuitry needed?

No internal reverse-voltage protection exists. Due to the P-channel MOSFET's intrinsic body diode, current flows from OUT to IN when VOUT > VIN-potentially damaging the IC. An external Schottky diode (cathode to IN, anode to GND) is required in applications with backup batteries or hot-swap scenarios, as detailed in the Application Information section.

What is the output voltage accuracy over temperature and load?

At 25°C and zero load, output is 2.463V to 2.537V (±1.5%). Over full operating range (-40°C to +125°C ambient, 0–100mA load), accuracy degrades to 2.4V to 2.6V (±4%), as guaranteed in the Electrical Characteristics table. This includes initial tolerance, line/load regulation, and thermal drift effects.

Can this part be used with tantalum or polymer capacitors on the output?

The datasheet explicitly recommends ceramic capacitors (X5R/X7R) ≥0.47μF for stability. Tantalum and polymer capacitors exhibit higher ESR and capacitance variation over temperature/voltage, which may cause oscillation or degraded transient response. Ceramic-only designs are validated; alternatives require full bench characterization per application.
