1.0Amp Low Dropout Voltage Regulator

B1117

Adjustable & Fix (0.40Volt Dropout)

Description

Features

•

Adjustable Output Down to 1.2V

The Bay Linear B1117 is a three terminal positive NPN

regulator offered as adjustable or fix voltages of 1.5V,1.8V,

2.5V, 2.85V, 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 B1117

Dropout of 0.40 V in for B1117A

Adjustable & Fix 1.5V, 1.8V, 2.5V, 2.85V,

3.0V, 3.3V, 5.0V

•

0.05% Load Regulation

Current & Thermal Limiting

Lower Cost SOT-89 Package

Available in SOT-223, and TO-252,

TO-263 & SO-8

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.

•

Similar to industry Standard LT1117

The B1117 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.
