Monolithic Power Systems Inc. EV2009EE-00A

Overview

EV2009EE-00A from Monolithic Power Systems is an evaluation board for the MP2009EE-1.8 ultra-low-noise, low-dropout linear regulator IC. It delivers 1.8V output at up to 120mA from a 2.3–6.0V input, features 172mV dropout, 16µVRMS output noise (100Hz–100kHz), and stable operation with 1µF ceramic capacitors.

For engineers reviewing the EV2009EE-00A datasheet, EV2009EE-00A pinout, EV2009EE-00A application, or EV2009EE-00A equivalent, this board enables rapid validation of MP2009 performance in noise-sensitive analog power rails-especially for VCOs, RF front-ends, and portable battery-powered systems requiring fast transient response and minimal PSRR degradation.

Technical Context

The EV2009EE-00A implements the MP2009EE-1.8 LDO in a 5-pin SC70 package with fixed 1.8V output, enabling direct evaluation of its ultra-low-noise regulation without external feedback components. Its EN pin is pre-biased via a 100kΩ resistor to VIN for automatic startup, and thermal shutdown + current limiting are fully functional on-board.

Designed for minimal external components, the board uses only two 1µF X7R 0603 ceramic capacitors (CIN/COUT) and requires no bypass capacitor for specified noise performance-leveraging the MP2009's internal architecture optimized for high PSRR (78dB @ 1kHz) and fast load-line transient recovery.

FAQ

What is the purpose of the EV2009EE-00A evaluation board?

The EV2009EE-00A is a ready-to-use hardware platform for evaluating the MP2009EE-1.8 LDO's electrical performance-including noise, PSRR, dropout, and transient response-under real-world conditions. It is not a production-ready power module but a design verification tool with validated layout and component selection.

Can the output voltage be adjusted on this board?

No. The EV2009EE-00A is configured exclusively for 1.8V output using the MP2009EE-1.8 variant. The IC has a fixed output; no resistor divider or external feedback network is present. For other voltages, refer to MP2009 variants (e.g., MP2009EE-2.5, MP2009EE-3.3) and their corresponding evaluation boards.

What input and output capacitors are used on the board?

The board uses two 1µF, 16V X7R ceramic capacitors in 0603 package (TDK C1608X7R1C105K) for both input (CIN) and output (COUT). These meet the MP2009's stability requirement and enable full-spec noise and transient performance without additional capacitance.

How is the EN pin configured, and can it be controlled externally?

The EN pin is pulled high to VIN through a 100kΩ resistor (R1), enabling automatic startup. A test point is provided to ground EN directly for shutdown testing. No level-shifting or active logic interface is included-external control requires simple open-drain or push-pull GPIO connection to the EN test point.

Does this board include thermal protection demonstration capability?

Yes. The MP2009EE-1.8 IC on the board retains full thermal overload protection per its datasheet specification. Under sustained 120mA load with inadequate airflow or elevated ambient temperature (>85°C), the device will throttle output current and reduce junction temperature autonomously-observable as output voltage sag or intermittent regulation.

Is the EV2009EE-00A RoHS compliant and lead-free?

Yes. All components-including the MP2009EE-1.8 IC (5-pin SC70, lead-free matte tin finish), TDK capacitors, and PCB-are RoHS 2011/65/EU compliant and manufactured with lead-free processes. The board documentation (Rev. 1.0, 2009) confirms compliance with MPS's environmental policy at time of release.
