Monolithic Power Systems Inc. EV2016DJ-00A

Overview

EV2016DJ-00A from Monolithic Power Systems is an evaluation board for the MP2016DJ low-dropout linear regulator, designed to validate high-voltage, low-quiescent-current power delivery in battery-powered systems. It supports 7–42V input, delivers 5V output at up to 30mA, features ±2% output accuracy, 50dB PSRR, and thermal shutdown protection.

For engineers reviewing the EV2016DJ-00A datasheet, EV2016DJ-00A pinout, EV2016DJ-00A application, or EV2016DJ-00A equivalent, this board enables rapid validation of adjustable-output LDO performance under line/load transients, dropout conditions, and thermal stress in portable and smart-battery applications.

Technical Context

The EV2016DJ-00A implements the MP2016DJ IC in a fully assembled TSOT23-5 footprint layout with external resistor divider (R1 = 76.8kΩ, R2 = 24.9kΩ) presetting VOUT to 5.0V. EN is pulled high via 100kΩ to VIN for automatic startup, and SHDN functionality is accessible via U1 Pin 1.

It integrates input decoupling (C1 = 1μF/50V X7R), output bulk capacitance (C2 = 4.7μF/25V X7R), and feedback bypass (C3 = 22nF/50V X7R), all placed per MPS layout guidelines to ensure stability across 0–40mA load and 7–42V input range.

FAQ

What is the default output voltage and how is it set?

The board is configured for 5.0V output using a precision 76.8kΩ (R1) and 24.9kΩ (R2) resistor divider on the FB pin of the MP2016DJ. The feedback threshold is 1.23V, yielding VOUT = 1.23V × (1 + R1/R2) = 5.00V. Resistor tolerances are ±1% to maintain ±2% overall accuracy.

Can the output voltage be adjusted, and what is the supported range?

Yes - VOUT is fully adjustable from 1.2V to 24V by changing R1 and R2 per the formula VOUT = 1.23V × (1 + R1/R2). R2 must remain 24.9kΩ ±1% for accuracy; R1 is selected accordingly. The MP2016DJ's internal reference and error amplifier support this full range with guaranteed stability.

How is enable/shutdown controlled on this board?

Pin 1 (SHDN) of U1 is routed to a test point and also tied to VIN through a 100kΩ pull-up resistor (R3), enabling automatic startup when input is applied. To disable the regulator, drive SHDN low (≤0.4V) externally - the shutdown current drops to <1.5µA as specified for the MP2016DJ.

What capacitors are used for input and output filtering?

C1 (1μF, 50V X7R, 1206) provides input high-frequency decoupling; C2 (4.7μF, 25V X7R, 1206) serves as output bulk capacitance; C3 (22nF, 50V X7R, 0603) bypasses the FB node to improve transient response and noise immunity. All are placed per MPS layout recommendations.

Does this board support thermal testing, and what protection features are active?

Yes - the MP2016DJ on this board retains its full protection suite: thermal shutdown triggers at ~150°C junction temperature, and current limiting activates at ~50mA peak. Board copper pour and component placement allow direct IR thermography of the IC during sustained load testing.
