Description
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.
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.
The B033 is offered in a 3-pin SOT-223, and TO-252 (DPAK)
packages compatible with other 3 terminal regulators.
5-pin
version in TO-263 with lower dropout of 0.4 volt is
available.
