Adjustable Output Down to 1.2V
The Bay Linear B033 is a three terminal positive NPN
regulator offered as adjustable or fix voltages of 1.8V, 2.5V,
3.0V, 3.3V, and 5Volts. The output current has a capability up
to 1.0Amp,. This device has been optimized for low voltage
where transient response and minimum input voltage are
critical. The 2.85V version is designed specifically to be used
in active terminators for SCSI bus.
Output Current of 1.0Amp
Low Dropout 1.0V for B033
Dropout of 0.40 V in for B033A
Adjustable & Fix 1.8V, 2.5V, 3.0V, 3.3V,
5.0V
Current & Thermal Limiting
Lower Cost SOT-89 Package
Available in SOT-223, and TO-252, &
TO-263

Current limit is trimmed to ensure specified output current and
controlled short-circuit current. On-Chip thermal limiting
provides protection against any combination of overload and
ambient temperatures that would create excessive junction
temperatures.
