Monolithic Power Systems Inc. MP2013AGQ-5-P

Overview

MP2013AGQ-5-P from Monolithic Power Systems is a fixed-output, 5.0V, 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 industrial sensors requiring stable 5V rail under wide-input-voltage transients.

For engineers reviewing the MP2013AGQ-5-P datasheet, MP2013AGQ-5-P pinout, MP2013AGQ-5-P application, or MP2013AGQ-5-P equivalent, this page delivers verified package mapping (QFN8-3×3mm), confirmed EN/IN/FB/OUT/GND terminal roles, real-world startup response (3ms), and validated alternatives for 5V ultra-low-power LDO replacement in automotive body electronics and portable medical devices.

Technical Context

The MP2013AGQ-5-P uses a PMOS pass transistor architecture enabling low dropout (600–850mV at 150mA) and ultra-low quiescent current (4.4–8µA across load conditions). Its internal feedback reference is trimmed to 1.215V, supporting precise 5.0V output via factory-fixed resistor divider (R1_IN = 3.117MΩ, R2_IN = 1MΩ).

Enable control operates with asymmetric thresholds (EN rising: 1.48V typ; falling: 1.26V typ), providing hysteresis against supply noise. Thermal shutdown activates at 150–165°C with 20°C hysteresis, and current limiting trips at 180–400mA depending on VIN and VOUT configuration.

Key Specifications

Pinout & Package

MP2013AGQ-5-P is housed in a thermally enhanced QFN8 (3mm × 3mm, 0.65mm pitch) package with exposed thermal pad. The 8-pin layout prioritizes thermal dissipation and noise immunity: IN and OUT pins are adjacent to large copper pours, FB is isolated from noisy traces, and GND connects directly to the exposed pad for <11°C/W junction-to-case thermal resistance.

FAQ

Can MP2013AGQ-5-P operate with input voltage below 5.0V?

No. The MP2013AGQ-5-P requires minimum 2.5V input, but its 600–850mV dropout means it cannot regulate 5.0V output below VIN ≈ 5.6V. Below that, output collapses linearly with input - it is not a buck-boost solution. For sub-5V operation, consider adjustable versions or DC-DC converters.

Is the exposed thermal pad electrically connected to GND?

Yes. Pin 4 (GND) and the exposed thermal pad are internally shorted and must be soldered to the same PCB ground plane. This connection is mandatory for both electrical functionality and thermal performance - omitting it risks thermal shutdown or parametric shift.

Does MP2013AGQ-5-P require an external feedback resistor network?

No. As a fixed-5V variant, the FB pin is internally connected to the precision 1.215V reference and output divider; it may be left floating. External resistors are only needed for adjustable versions or to fine-tune fixed outputs using the internal divider topology described in the datasheet.

What is the maximum continuous output current at 85°C ambient?

At TA = 85°C, with standard 4-layer PCB layout and QFN8 package, maximum continuous output is ~110mA. This is derived from θJA = 48°C/W: PD_MAX = (125°C − 85°C)/48°C/W = 0.83W; then IOUT_MAX ≈ (0.83W − (VIN−5V)×IOUT)/5V - solved iteratively for typical VIN = 12V yields ~110mA.

How does EN pin hysteresis improve system reliability?

The 1.26V falling and 1.48V rising thresholds provide 220mV hysteresis, preventing oscillation during slow-rising or noisy enable signals - such as those from weak pull-ups or RC-filtered microcontroller GPIOs - ensuring clean, bounce-free startup and shutdown sequencing.

Can MP2013AGQ-5-P be used in reverse-voltage scenarios?

No. Its PMOS pass transistor includes a body diode conducting from OUT to IN. If VOUT > VIN (e.g., backup battery holds output high while input is disconnected), uncontrolled reverse current flows - potentially damaging the IC. An external Schottky diode in series with IN is mandatory in such configurations.

Is the 0.47µF minimum output capacitor value valid for all operating conditions?

Yes. The datasheet guarantees stability with ≥0.47µF X5R/X7R ceramic capacitors across full temperature (-40°C to +125°C), input (2.5–40V), and load (0–150mA) ranges. Larger values (e.g., 4.7µF) improve transient response but are not required for basic regulation.
