TPS72301QDBVRQ1概述

    Product Introduction
    The TPS723xx-Q1 series is a family of low-dropout (LDO) negative voltage regulators designed to cater to high-demand applications requiring minimal noise and excellent power supply rejection ratios (PSRR). These devices deliver stable, precise negative voltages suitable for optical drives, networking equipment, video amplifiers, and other noise-sensitive electronic systems. They are available in fixed-output options of -2.5V and adjustable configurations ranging from -1.2V to -10V, offering broad applicability across various industries.
    Technical Parameters
    - Input Voltage Range: -10V to -2.7V
    - Output Voltage Options: Fixed (-2.5V), Adjustable (-1.2V to -10V)
    - Output Current: Up to 200mA
    - Quiescent Current: Less than 2μA in shutdown mode
    - Output Noise: 60 μVRMS typical (10Hz to 100kHz bandwidth)
    - Power Supply Rejection Ratio (PSRR): 65 dB at 1kHz
    - Dropout Voltage: ~280mV typical at 200mA, -2.5V output
    - Thermal and Overcurrent Protection: Integrated thermal shutdown and overcurrent protection mechanisms
    - Package Type: SOT23-5 (DBV), measuring 2.90mm x 1.60mm
    - Operating Temperature Range: -40°C to 125°C
    Product Features and Advantages
    1. Automotive Qualification: The TPS723xx-Q1 series complies with AEC-Q100 standards, making them suitable for automotive-grade applications.
    2. Ultralow Noise: Offers exceptional performance with typical output noise as low as 60 μVRMS, ensuring compatibility with sensitive analog circuits.
    3. High PSRR: With a typical PSRR of 65 dB at 1kHz, it effectively suppresses ripple and noise from the input power source.
    4. Compact Design: Its SOT23-5 package makes it highly space-efficient, facilitating integration in compact PCB designs.
    5. Precise Accuracy: Maintains overall accuracy within ±2%, covering variations due to line, load, and temperature fluctuations.
    6. Enhanced Reliability: Features thermal and overcurrent protections, extending the lifespan and robustness of the device.
    Application Scenarios and Recommendations
    The TPS723xx-Q1 finds widespread usage in critical applications like:
    - Optical Drives: Where accurate and stable negative voltages are essential for signal integrity.
    - Optical Networking: Beneficial in minimizing noise interference within high-speed communication systems.
    - RF and Analog Circuits: Ideal for minimizing jitter and enhancing signal quality in RF modules.
    Use Case Example: For video amplifiers where low noise and high PSRR are paramount, the TPS723xx-Q1 ensures clean and stable voltage outputs. To optimize performance, always place the recommended 2.2μF ceramic output capacitor near the device’s OUT pin and connect a 0.01μF capacitor to the NR pin for enhanced noise suppression.
    Recommendation: When designing circuits involving high-frequency signals, use additional ferrite beads and filtering capacitors if necessary to further enhance PSRR and minimize output noise.
    Compatibility and Support
    The TPS723xx-Q1 is fully compatible with industry-standard input/output configurations and can operate seamlessly alongside common power management ICs. Texas Instruments provides extensive documentation, including datasheets, application notes, and software tools, to assist engineers during the design phase. Furthermore, the company offers robust customer support through forums and direct technical assistance to address any issues encountered during implementation.
    Common Issues and Solutions
    | Issue | Solution |

    | High Output Noise | Add a 0.01μF capacitor to the NR pin to reduce noise by up to 60%. |
    | Insufficient Current Limit | Ensure proper heat dissipation; derating at temperatures above 70°C. |
    | Unstable Output Voltage | Verify correct placement of 2.2μF cera
