Description
The B4041 is a two-terminal, temperature compensated,
band-gap voltage reference, which provides a fixed
1.25V output for input currents between 500 µA to
5mA. The bandgap voltage (1.225V) is independently
laser trimmed from the output voltage to achieve a very
low tempco, then the output voltage is laser trimmed to
1.225 volts. This trimming technique and the low
tempco (A grade 50 ppm/ °C) thin film resistor process
gives a very stable device over the full temperature
range. The B4041 is available in the sub-miniature
(3mm × 1.3mm) SOT-23, SO-8 surface mount package,
or TO-92 package. The operating temperature is -40°C
to 85°C.
The Bay Linear B4041 advanced design eliminates the
need for an external stabilized capacitor while insuring
stability with any capacitive load, making them easy to
use.
