LT337AH概述

    Product Introduction
    The LT137A/LM137 and LT337A/LM337 are negative adjustable regulators designed to deliver stable and precise outputs across a wide voltage range. These devices are ideal for applications requiring high reliability and performance, especially in the domain of system power supplies, precision voltage/current regulators, and onboard regulators.
    Key features include adjustable output voltage ranging from –1.2V to –37V, capable of supplying up to 1.5A output current. The regulators boast advanced design improvements over their predecessors, offering superior line and load regulation, with a maximum output voltage error of just 1%.
    Technical Parameters
    The following table summarizes the key technical specifications of the LT137A/LM137 and LT337A/LM337:
    | Parameter | Typical Value | Min-Max Range | Unit |
    ||
    | Reference Voltage | -1.25V | -1.238 to -1.262 | V |
    | Line Regulation | 0.005%-0.03%/V %/V |
    | Load Regulation | 0.1%-1% % |
    | Thermal Regulation | 0.002%-0.04%/W %/W |
    | Adjust Pin Current | 65-100μA μA |
    | Minimum Load Current | 1.2-5mA mA |
    | Current Limit | 0.5-2.2A A |
    | Thermal Resistance | 2.3°C/W (H Package) °C/W |
    The regulators operate in extreme environments, with an operating junction temperature range of:
    - LT137A/LM137: -55°C to 150°C
    - LT337A/LM337: 0°C to 125°C
    They also feature advanced burn-in testing (100% thermal limit burn-in) to ensure zero-field failures.
    Product Features and Advantages
    The LT137A/LM137 and LT337A/LM337 offer numerous advantages that make them stand out in the electronic components market:
    - Guaranteed Voltage Tolerance: ±1% initial accuracy ensures high precision.
    - Excellent Regulation Characteristics: Line and load regulation are significantly enhanced compared to previous designs.
    - Thermal Stability: Thermal limiting protects against overheating even without a heatsink.
    - Advanced Burn-in Process: Ensures 100% reliability and minimizes field failures.
    - Protection Features: Internal current and power limiting safeguard against overload and short-circuit conditions.
    - Wide Application Range: Suitable for precision voltage regulation in various industries including telecommunications, industrial electronics, and automotive systems.
    These advantages position the LT137A/LM137 and LT337A/LM337 as highly competitive solutions for demanding applications.
    Application Case Studies and Usage Recommendations
    Example Applications:
    1. Precision Voltage Regulators: Used in medical equipment, scientific instruments, and laboratory power supplies to provide stable output voltages.
    2. System Power Supplies: Integral in industrial automation systems and data centers where multiple voltages are required.
    3. On-Board Regulators: Ideal for integrating into PCB designs, providing local regulation near sensitive circuits.
    Usage Tips:
    - Ensure proper layout of divider resistors (R1 & R2) as per the datasheet recommendations to avoid degrading load regulation.
    - For output voltages exceeding 6V, use a diode between input and output to prevent damage due to large capacitance.
    - Bypass the adjustment pin with a capacitor to reduce ripple and noise, ensuring it has a voltage rating at least equal to the output voltage.
    Compatibility and Support
    The LT137A/LM137 and LT337A/LM337 are compatible with a variety of existing electronic circuits and systems. They can be easily integrated with other standard components, sim
