Monolithic Power Systems Inc. EV2015A-JE-Q-G-00A

Overview

EV2015A-JE-Q-G-00A from Monolithic Power Systems is a fully assembled and tested evaluation board for the MP2015A low-quiescent-current linear regulator, designed to validate 5V/150mA regulation from 6–24V input in battery-powered systems. It supports three package variants (TSOT23-4, QFN-6, QFN-8) via jumper-selectable IC mounting and features ±2% output accuracy, 700mV dropout at full load, and operation down to 3.3µA quiescent current.

For engineers reviewing the EV2015A-JE-Q-G-00A datasheet, EV2015A-JE-Q-G-00A pinout, EV2015A-JE-Q-G-00A application, or EV2015A-JE-Q-G-00A equivalent, this board enables rapid validation of MP2015A performance under real-world input range (6–24V), load step response, thermal behavior, and ceramic capacitor stability with ≥0.47μF output capacitance.

Technical Context

The EV2015A-JE-Q-G-00A implements a hardware-configurable platform for evaluating the MP2015A's fixed 5V output variant across three physical packages. Jumper-selectable JP1–JP6 allow direct substitution of MP2015AGJE (TSOT23-4), MP2015AGQ (QFN-8), or MP2015AGG (QFN-6) without PCB rework.

Board-level design incorporates six 1μF/50V X7R and six 4.7μF/25V X5R ceramic capacitors for input/output filtering, plus precision 1% feedback resistors (2.4MΩ and 768kΩ) enabling accurate VOUT verification and optional adjustment per MP2015A's adjustable version reference design.

FAQ

What IC packages does the EV2015A-JE-Q-G-00A support?

The board supports three MP2015A variants via jumper configuration: MP2015AGJE in TSOT23-4 (JP1+JP4), MP2015AGQ in QFN-8 (JP2+JP5), and MP2015AGG in QFN-6 (JP3+JP6). Each IC occupies its dedicated footprint with matching pad layout and thermal relief.

Can the output voltage be adjusted on this board?

No - the EV2015A-JE-Q-G-00A is configured for fixed 5V output only. Though the underlying MP2015A offers adjustable versions, this board uses a hard-wired 2.4MΩ/768kΩ resistor divider optimized for 5V, and no solder jumpers or trim pots are provided for VOUT modification.

What is the minimum input voltage required for regulation at 150mA?

At 150mA load, the board requires ≥5.7V input to maintain 5V output due to the MP2015A's 700mV dropout voltage. Below 5.7V, output drops linearly; regulation is guaranteed only within the 6–24V specified input range.

Are test points provided for measuring input/output ripple and transient response?

Yes - the board includes dedicated V_IN, V_OUT, and GND test points adjacent to each IC footprint and connector. These are routed with short, low-inductance traces to enable accurate oscilloscope probing of AC ripple, load-step response, and startup waveforms.

Does the board include thermal monitoring or overtemperature protection indicators?

No discrete thermal sensor or indicator LED is present. However, the MP2015A ICs themselves integrate thermal shutdown circuitry that disables output above ~150°C junction temperature - verified during board-level stress testing per MPS datasheet conditions.

What is the recommended output capacitor value for stable operation?

The board uses 1μF and 4.7μF X7R/X5R ceramics per rail, validating MP2015A's stability with ≥0.47μF total output capacitance. For production designs, 2.2μF–10μF X5R/X7R (6.3V–16V rating) is recommended to ensure phase margin >45° across temperature and aging.
