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.
