Monolithic Power Systems Inc. EV20056-G-00A

Overview

EV20056-G-00A from Monolithic Power Systems is an evaluation board for the MP20056-G-18 low-noise, high-PSRR linear regulator IC, delivering 1.8V/250mA output from 2.5–5.5V input with 100mV dropout at full load, 13μVRMS output noise, and 70dB PSRR at 1kHz-designed for powering FPGA core rails in portable instrumentation.

For engineers reviewing the EV20056-G-00A datasheet, EV20056-G-00A pinout, EV20056-G-00A application, or EV20056-G-00A equivalent, this board enables rapid validation of transient response, thermal behavior, and enable-controlled sequencing in battery-powered 1.8V subsystems.

Technical Context

The EV20056-G-00A implements a fixed-output (1.8V), PMOS-based LDO using the MP20056-G-18 QFN-8 (2mm × 2mm) IC. It supports active enable control (EN threshold: 1.5V high / 0.4V low) and integrates current limiting and thermal shutdown.

Test conditions confirm operation across 2.5–5.5V input range with ≤150μA ground current at no load, enabling ultra-low quiescent power delivery to noise-sensitive analog and digital loads such as DSP I/O supplies and handheld instrument sensors.

FAQ

What input voltage range is supported by the EV20056-G-00A?

The board accepts 2.5V to 5.5V DC input on the VIN pins. Operation below 2.5V may cause dropout or regulation loss; above 5.5V risks damage to the MP20056-G-18 IC and bypass capacitors rated for 6.3V.

How is the enable function implemented on this evaluation board?

The EN pin (Pin 5 of U1) accepts TTL/CMOS-compatible logic: ≥1.5V enables regulation, ≤0.4V disables output. No external pull-up is required-the board includes no default bias, so EN must be actively driven.

Can the output voltage be adjusted to values other than 1.8V?

No. The MP20056-G-18 IC used on this board has an internally trimmed, fixed 1.8V output. There is no feedback resistor network or external adjustment option on the EV20056-G-00A layout.

What are the key decoupling capacitors used and why?

C1 (2.2μF X5R, 0603) and C2 (4.7μF X5R, 0603) provide bulk and high-frequency input/output filtering. Their low-ESR ceramic construction ensures stability and supports the regulator's fast transient response under dynamic load steps.

Does the board include thermal management features beyond IC-level protection?

Yes. The PCB uses 2oz copper on the top layer with exposed thermal pad under U1 (QFN-8), directly soldered to the IC's thermal pad. This enhances heat dissipation during continuous 250mA operation at elevated ambient temperatures.

Is the EV20056-G-00A RoHS and halogen-free compliant?

Yes. All components-including the MP20056-G-18 IC, Murata capacitors, and PCB finish-are lead-free, halogen-free, and fully compliant with the EU RoHS directive, as confirmed by MPS and component manufacturer declarations.
