AN-CM-408 How to measure PSRR for SLG5100X PMICs
PDF 1.25 MB 2025年3月28日
AI 生成的摘要: Power Supply Rejection Ratio (PSRR) measurement for SLG5100X PMICs evaluates how effectively LDO regulators maintain stable output voltage despite input voltage fluctuations. The measurement covers frequencies from 10 Hz to 10 MHz using equipment such as the Keithley 2460 power supply, Picotest J2120A line injector, and Omicron Lab Bode 100 network analyzer. The setup involves injecting AC ripple into the input, monitoring input/output voltages, and analyzing data to calculate PSRR. Detailed test conditions for various LDO types and calibration procedures ensure accurate and reliable PSRR characterization, supporting robust power management design.

AN-CM-405 SLG51003 Remote Sense Functionality
PDF 1.06 MB R19AN0321EE0300 Rev.3.00 2025年3月11日
AI 生成的摘要: Remote Sense functionality compensates for voltage drops caused by parasitic resistance and inductance between the LDO1 output and the load, especially in high current applications or when using long wires or flexible printed circuit (FPC) connectors. By sensing voltage at the load rather than the regulator output, it maintains accurate voltage delivery despite trace losses. The SLG51003 configures GPIO1 as an analog input for remote sensing, requiring VDDIO voltage higher than LDO1 output. This mode reduces the need for large output capacitors, saving PCB space and cost. Practical tests demonstrate significant voltage drop compensation across various wire lengths and load currents, highlighting the importance of proper ground routing to minimize residual voltage drops.

AN-CM-399 Enhancing LDO PSRR and Noise Performance Measurements Using Capacitors with Low Parasitic Parameters
PDF 1.74 MB R19AN0369EE0100 Rev.1.00 2024年11月04日
AI 生成的摘要: Low-dropout (LDO) voltage regulators maintain stable output voltage by rejecting input power supply noise and fluctuations, measured by Power Supply Rejection Ratio (PSRR). PSRR varies with frequency, voltage ripple, and load conditions, requiring careful measurement and capacitor selection. Using capacitors with low Equivalent Series Inductance (ESL) and Equivalent Series Resistance (ESR) improves PSRR and noise performance. Accurate PSRR measurement demands high-quality equipment and consideration of temperature and load variations. Noise sources within LDOs affect sensitive circuits, necessitating strategies to minimize output noise while balancing stability and efficiency.

AN-CM-400 Noise Component Role in Forming Image Quality
PDF 804 KB 2024年10月18日
AI 生成的摘要: Power supply noise significantly impacts image quality in image sensor applications by causing pixel artifacts and reducing signal-to-noise ratio (SNR). Stable power delivery across multiple voltage rails is essential, with noise sources including power ripple, EMI, ground loops, and transient loads. Low-dropout regulators (LDOs) and power management ICs (PMICs) help filter noise. A test bench using Raspberry Pi 4 and Camera module V2 evaluates noise effects, comparing default LDO with SLG51003V, which offers superior power supply rejection ratio (PSRR) and noise suppression. Image quality analysis shows SLG51003V reduces noise artifacts and maintains clearer images under noisy conditions, proving its effectiveness in noise-sensitive sensor applications.
