Note 1: Dice are probe tested at 25°C to the limits shown except for high

current tests. Dice are tested under low current conditions which assure

full load current specifications when assembled in packaging systems

approved by Linear Technology. For absolute maximum ratings, typical

specifications, performance curves and finished product specifications,

please refer to the standard product RH data sheet.

Note 2: Testing is done using a pulsed low duty cycle technique. See

thermal regulation specifications in the LT1185 data sheet for output

changes due to heating effects.
