Monolithic Power Systems Inc. MP2013AGQ-33-P

Overview

MP2013AGQ-33-P from Monolithic Power Systems is a fixed-output 3.3V, 150mA low-quiescent-current linear regulator with 2.5V–40V input range, 620mV dropout at full load, ±2% output accuracy, and thermal shutdown protection-designed for battery-powered microcontrollers and industrial sensors requiring ultra-low standby power.

For engineers reviewing the MP2013AGQ-33-P datasheet, MP2013AGQ-33-P pinout, MP2013AGQ-33-P application, or MP2013AGQ-33-P equivalent, key selection criteria include quiescent current (4.4–10 µA at no load), dropout voltage under 150mA load, FB pin functionality for optional adjustment, and QFN8 (3mm×3mm) thermal performance in high-temperature environments.

Technical Context

The MP2013AGQ-33-P implements a PMOS pass transistor architecture enabling low-dropout operation across its 2.5V–40V input range while maintaining stable regulation at 3.3V output. Its internal 1.215V reference and feedback loop deliver ±2% accuracy over –40°C to +125°C junction temperature.

Enable control is implemented via a precision EN pin with 1.26V falling threshold and 1.48V rising threshold, supporting external UVLO configuration. Thermal shutdown activates at 150°C with 20°C hysteresis, and current limiting caps peak output at 270mA to protect against overload.

FAQ

What is the minimum input voltage required for regulation at 3.3V output?

The MP2013AGQ-33-P maintains regulation down to VIN = VOUT + VDROPOUT. With a maximum dropout of 850mV at 150mA, the minimum functional input is 4.15V. At lighter loads, dropout falls below 700mV, allowing stable operation from 4.0V input.

Can the FB pin be used to adjust the output voltage of the MP2013AGQ-33-P?

Yes-the MP2013AGQ-33-P retains the FB pin from the adjustable MP2013A base design. Though configured for 3.3V, connecting an external resistor divider between OUT and GND allows reprogramming the output from 1.215V to 15V, using the internal 1.716MΩ/1MΩ divider as baseline.

Is an input capacitor required, and what value is recommended?

Yes-an input ceramic capacitor is mandatory for stability and transient suppression. MPS specifies a 1µF to 10µF X5R or X7R capacitor placed directly between IN and GND, with 4.7µF commonly used in reference designs to balance ESR, size, and line regulation performance.

How does thermal performance differ between QFN6 and QFN8 packages?

The QFN8 (3mm×3mm) package has θJA = 48°C/W versus 80°C/W for QFN6 (2mm×2mm), meaning it dissipates heat 1.7× more effectively on identical PCBs. At 150mA and 12V input, QFN8 junction rise is ~50°C lower-critical for operation above 85°C ambient or in enclosed enclosures.

Does the MP2013AGQ-33-P include reverse-voltage protection?

No-it lacks internal reverse-current blocking. When VOUT > VIN (e.g., backup battery scenario), the PMOS body diode conducts uncontrolled current from OUT to IN. An external Schottky diode in series with the IN pin is required to prevent damage in such configurations.

What is the purpose of the NC pins (3 and 7) in the QFN8 package?

Pins 3 and 7 are no-connect terminals. They may be left floating or tied to GND to enhance thermal conduction from the exposed pad without affecting electrical function-recommended for high-power or high-ambient-temperature deployments to reduce junction temperature.

How does the EN pin behave during power-up and brownout conditions?

The EN pin features asymmetric thresholds: rising threshold is 1.48V (±0.1V), falling threshold is 1.26V (±0.08V), providing 220mV hysteresis. This prevents oscillation during slow-rising inputs and ensures clean, glitch-free enable/disable transitions during voltage sags.
