THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 For technical support, please contact: analogswitchtechsupport@vishay.com Notes: a. VIN UVLO is programmable using a resistor divider from VIN to ENL to AGND. The ENL voltage is compared to an internal reference. b. Guaranteed by design. c. The switch-over threshold is the maximum voltage diff erential between the VLDO and VOUT pins which ensures that VLDO will internally switch-over to VOUT. The non-switch-over threshold is the minimum voltage diff erential between the VLDO and VOUT pins which ensures that VLDO will not switch-over to VOUT. d. The LDO drop out voltage is the voltage at which the LDO output drops 2 % below the nominal regulation point.
