Precision Micro power Voltage Reference

B4041

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.
