Notes:
(1) All parameters, except nominal output voltage are specified for the variable voltage version, allowing a wider Vin Range.
The specified limits also apply for the fixed voltage versions over the allowable input voltage range: GS1084-1.8 (3.2V - 7.0V), GS1084-2.5 (3.9V - 7.0V),
GS1084-3.3 (4.75V - 7.0V).
(2) To maintain the specified junction temperatures, low duty cycle pulse testing is required for most parameters.
Notes:
VREF = VOUT ? VADJ = 1.25V (typ.)
VOUT = VREF x (1+R2/R1) + IADJ x R2
IADJ = 55
A (typ.)
(1) C1 needed if device is far away from filter capacitors
(2) C2 required for stability
