Dual 1.0Amp Low Dropout
Voltage Regulator
B2117
Description
The Bay Linear B2117 is a five terminal Dual positive NPN
regulator offered as adjustable or fix voltages of 1.8V, 2.5V,
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
www.DataSheet4U.ccormitical.
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 B2117 is offered in a 5-pin SOT-263,
