ELECTRICAL CHARACTERISTICS (continued)
Limits in standard typeface are for TJ = 25°C, and limits in boldface type apply over the full operating temperature range.
Unless otherwise specified: VIN = VO(NOM) + 1V, IL = 1 mA, COUT = 1 μF, VON/OFF = 2V.

(3) The ON/OFF inputs must be properly driven to prevent misoperation. For details, refer to ON/OFF INPUT OPERATION.
(4) See related curve(s) in TYPICAL PERFORMANCE CHARACTERISTICS section.
Typical Application Circuit
*ON/OFF input must be actively terminated. Tie to VIN if this function is not to be used.
**Minimum Output Capacitance is 1 μF to insure stability over full load current range. More capacitance provides
superior dynamic performance and additional stability margin (see APPLICATION HINTS).
***Do not make connections to this pin.
