4 / 8 page FAN1537 PRODUCT SPECIFICATION 4 REV. 1.1.1 3/20/02 Application Hints External Capacitors Like any low-dropout regulator, the FAN1537 requires external capacitors for stability. Input Capacitor A Tantalum input capacitor of 22µF is recommended. This capacitor must be located at a distance of no more than 0.5" from the input pin of the device and returned to a clean ana- log ground. Output Capacitor The FAN1537 is designed to work with Ceramic or Tantalum load capacitors. A value of 22µF is recommended on each output, but the value can be reduced to 10µF to save space. Additional capacitance can be added without limit for better performance, e.g. improved transient response and lower noise. When a Ceramic multilayer capacitor is used, the X7R dielectric is recommended which holds the capacitance within ±15%. The output capacitor should be located not more than 0.5" from the output pins of the device and returned to a clean analog ground. |
