Monolithic Power Systems Inc. EV2013A-18-J-Q-G-00A

Overview

EV2013A-18-J_Q_G-00A from Monolithic Power Systems is a fully assembled and tested evaluation board for the MPQ2013AGQ-18 low-quiescent-current linear regulator, designed to validate operation of this 40V-input, 1.8V/150mA LDO in high-voltage battery-powered systems. It supports input voltages from 2.8V to 40V, delivers ±3% output accuracy, features thermal shutdown and current limiting, and targets ultra-low-power microcontrollers and portable industrial equipment.

For engineers reviewing the EV2013A-18-J_Q_G-00A datasheet, EV2013A-18-J_Q_G-00A pinout, EV2013A-18-J_Q_G-00A application, or EV2013A-18-J_Q_G-00A equivalent, this board enables rapid validation of MPQ2013AGQ-18 startup behavior, load transient response, dropout performance at 100mA (700mV), line regulation across 2.8–40V input, and EN-controlled enable/disable sequencing under real-world conditions.

Technical Context

The EV2013A-18-J_Q_G-00A implements a fixed-output 1.8V configuration using the MPQ2013AGQ-18 in QFN-8 (3×3mm) package, with internal feedback divider (0.482MΩ/1MΩ) and integrated EN logic threshold (1.48V turn-on, 1.26V turn-off). It includes three parallel 1μF/50V input capacitors and three 4.7μF/16V output capacitors to ensure stability and transient response per MPS design guidelines.

Board-level features include jumper-selectable IC variants (JP2/JP5 for MPQ2013AGQ-18), test points for VIN, VOUT, GND, and EN, and provisions for external FB resistor divider (R7/R8) or UVLO adjustment (R5/R6), enabling verification of adjustable-output and input undervoltage lockout configurations beyond the default 1.8V setup.

FAQ

What IC is populated on the EV2013A-18-J_Q_G-00A evaluation board?

The board is populated with the MPQ2013AGQ-18 - a 40V-input, 1.8V/150mA LDO in QFN-8 (3×3mm) package, featuring 700mV dropout at 100mA, ±3% output accuracy, thermal shutdown, and enable control with 1.48V turn-on threshold.

Can the output voltage be adjusted above or below 1.8V?

Yes - the board includes footprints and jumpers (R7/R8) to connect an external feedback resistor divider. The internal 1.215V reference and recommended R8 values (≤1MΩ at ≤105°C) allow precise VOUT tuning while maintaining stability and minimizing no-load current error.

How is enable functionality implemented and verified on this board?

EN is routed to a test point and controlled via jumper JP2 and resistor R5. Removing R5 allows direct EN voltage injection; applying >1.48V turns on the regulator, <1.26V shuts it down. Startup/shutdown waveforms, including transient response, are documented in the board's test report (Rev. 1.0, p.5–6).

Does the board support UVLO configuration, and how is it set?

Yes - resistors R5 and R6 form a divider from VIN to EN to set custom undervoltage lockout. With EN falling threshold fixed at 1.26V, selecting R5 = 2MΩ and R6 = 778kΩ sets VIN_UVLO_F to 4.5V, preventing regulator operation during brown-out conditions.

What capacitor types and values are used for input and output filtering?

The board uses three 1μF/50V X7R ceramic capacitors (1206) at the input and three 4.7μF/16V X7R ceramics (0805) at the output - matching MPS's recommended layout for optimal ESR, ESL, and transient suppression per the MPQ2013AGQ-18 datasheet.

Is thermal performance validated on this evaluation board?

Yes - the board's test results include short-circuit steady-state operation (p.6), confirming thermal shutdown activation under fault conditions. The QFN-8 package's exposed pad is soldered to the PCB ground plane, enabling direct junction-to-ambient thermal path measurement per JEDEC JESD51-7.
