Features
* s LNB selection and standby function s Built-in tone oscillator factory trimmed to 22-kHz, facilitates DiSEqC™ (a trademark of EUTELSAT) encoding s Tracking switch-mode power converter for lowest dissipation s Externally adjustable short-circuit protection s LNB short-circuit protection and diagnostApplications
* a precision 140-mΩ resistor is recommended. For 500-mA applications, the resistor value can be raised to 200-mΩ. In operation, the short-circuit protection produces current limiting at the input due to the tracking converter. If the output is shorted, the linear regulator will limit the output curr8282 Distributors
