Note 1: Add the model type suffix where the
X
is where D : DIP type, S : SMD type
Ex.) DIP type: BTB05-03S80D, SMD type: BTB05-03S80S
Note 2: The output voltage inside ( ) is when Vadj. and -Vout is short. The adjustable range of output voltages
are: 3.15-3.6V (3.3V products), 4.75-6V (5V products), 11.4-15V (12V products) respectively.
Note 3: The output current inside ( ) is when adjusted to the max. output voltage.
