Le blog de l'entreprise [ADI] Linear Regulator Evaluation Board ADP7185-3.3-EVALZ For Demonstrating the ADP7185 Ultra-Low-Noise Linear Regulator

Mingjiada Electronics has established a comprehensive service system for supplying and procuring ADI evaluation boards, particularly in the field of linear regulator evaluation boards. Below is a detailed introduction to the ADI ADP7185 evaluation board (ADP7185-3.3-EVALZ) and related service information.

Evaluation Board Core Information

The ADP7185-3.3-EVALZ evaluation board primarily demonstrates and evaluates the performance of the ADI ADP7185 ultra-low-noise, high-PSRR linear regulator. This board provides engineers with a convenient platform to conduct necessary testing and validation before integrating the chip into end products.

Key characteristics of the evaluation board and its core chip, the ADP7185:

Evaluation Board Functionality: Demonstrates the ADP7185 linear regulator's capabilities, supporting line/load regulation and voltage drop measurements.

Core Chip: ADP7185

Input voltage range: -2.0 V to -5.5 V

Output voltage: -3.3 V (fixed version)

Maximum output current: -500 mA

Power supply rejection ratio (PSRR): e.g., 68 dB @ 10 kHz

Output Noise: 4 µV rms (100 Hz to 100 kHz)

Dropout Voltage: Typical -190 mV @ -500 mA

Operating Temperature Range: -40°C to +125°C

Key Features: Ultra-low noise, high PSRR, low dropout voltage, externally adjustable output via resistor

Evaluation Board Capabilities and Advantages

Convenient Evaluation: This evaluation board enables straightforward measurement of key parameters such as line regulation, load regulation, and dropout voltage using only a single voltage source, voltmeter, ammeter, and load resistor.

Flexible Configuration: The board's adaptable design incorporates both a fixed voltage output from the ADP7185 itself and an adjustable output voltage version set via an external resistor divider (R1 and R2), facilitating testing under diverse operating conditions.

Comprehensive On-Board Components: The board integrates essential components including a 4.7μF input bypass capacitor, 1μF regulator capacitor, 0.01μF output voltage reference feedback capacitor, 1μF low-noise reference voltage capacitor, and 4.7μF output capacitor, ensuring immediate operation upon unboxing.

The ADP7185 evaluation board is ideally suited for noise-sensitive applications demanding stringent power quality, such as:

Precision data conversion systems

Communications and infrastructure equipment

Medical electronic instruments

Industrial and instrumentation equipment
