MAXIM INTEGRATED LDO稳压器 MAX8869EUE33

MAX8869EUE33概述

    # MAX8869 1A, MicroCap, Low-Dropout Linear Regulator
    Product Introduction
    The MAX8869 is a 1A low-dropout (LDO) linear regulator designed to operate within an input voltage range of +2.7V to +5.5V. It delivers a guaranteed 1A load current with a remarkably low dropout voltage of 200mV at full load. The MAX8869 offers precise output voltage options including preset values of +5V, +3.3V, +2.5V, +1.8V, and +1.0V, or an adjustable range from +0.8V to +5.0V via an external resistor divider. The product utilizes MicroCap™ technology, requiring only a small 1µF output capacitor for stability.
    Primary Features:
    - Output Current: Guaranteed 1A output current.
    - Low Dropout Voltage: Low 200mV dropout voltage at 1A.
    - Accurate Voltage Regulation: ±1% accuracy for preset outputs.
    - Compact Design: High-power 16-pin TSSOP package with dimensions 30% smaller than a standard SOT223.
    - Protective Features: Includes short-circuit protection, thermal shutdown, and adjustable soft-start capabilities.
    The MAX8869 is ideal for applications such as telecommunications hardware, network equipment, mobile phone base stations, personal computers, and battery-powered devices.
    Technical Parameters
    Key Specifications:
    | Parameter | Value | Unit |
    |
    | Input Voltage Range | 2.7 to 5.5 | V |
    | Output Voltage Options| +5.0V, +3.3V, +2.5V, +1.8V, +1.0V, adjustable | V |
    | Dropout Voltage | 200 | mV (typical) |
    | Output Current | 1 | A (continuous) |
    | Ground Current | 2.5 | mA (IOUT = 1A) |
    | PSRR @ 100kHz | 54 | dB |
    | Thermal Shutdown Temp | +170 | °C |
    Additional Electrical Characteristics:
    - Soft-Start: Adjustable soft-start time using an external capacitor.
    - Shutdown Supply Current: ≤ 10 µA (typical).
    - Short-Circuit Current Limit: Up to 1.9A.
    - Package Type: 16-pin TSSOP with an exposed pad (TSSOP-EP), height: 1.1mm.
    The device ensures stability with as little as 1µF output capacitance, making it highly efficient in compact designs.
    Product Features and Advantages
    The MAX8869 stands out with several unique features and advantages:
    1. High Power Density: Despite delivering up to 1A of current, the device occupies minimal space due to its small footprint and lightweight package.
    2. Advanced Protection Mechanisms: Includes short-circuit protection, thermal shutdown, and adjustable soft-start, ensuring robust performance across varying operating conditions.
    3. MicroCap™ Technology: Utilizes advanced MicroCap technology for higher efficiency and lower power consumption.
    4. Wide Input Voltage Range: Operates effectively over a broad input voltage range, enhancing flexibility in diverse applications.
    These features make the MAX8869 particularly well-suited for portable devices, battery-operated systems, and low-voltage microprocessor-based circuits where space and power management are critical.
    Application Cases and Usage Recommendations
    Typical Applications:
    - Telecommunications Hardware: Ensures stable power supply in routers, switches, and base stations.
    - Personal Computing Devices: Ideal for notebooks, desktops, and servers requiring reliable low-noise power regulation.
    - Embedded Systems: Suitable for embedded applications where precise and stable voltage regulation is needed.
    Usage Suggestions:
    - Use the MAX8869 with an external resistor divider for adjustable output voltages if the preset options do not meet specific requirements.
    - Ensure adequate heat dissipation by connecting the exposed pad to a large copper area on the PCB.
    - Always follow recommended layout guidelines for optimal performance and stability.
