GENERAL DESCRIPTION
For applications in tight quarters, the TCN4041 preci-
sion voltage reference is available in a space-saving
3mm x 1.3mm SOT-23B-3 surface mount package. The
TCN4041 eliminates the need for an external stabilizing
capacitor while maintaining stability with any capacitive
load. The minimum operating current is for both the TCN4041-
1.2V and the TCN4041-ADJ. Both versions have a maxi-
mum operating current of 12mA.
To ensure that the prime parts have an accuracy of
better than
±
0.5% (C grade) at 25
°
C, the TCN4041 uses
fuse and zener-zap reverse breakdown voltage trim during
wafer sort. Low dynamic impedance and bandgap reference
temperature drift curvature correction maintain stable re-
verse breakdown voltage accuracy over a wide range of
operating temperatures (– 40
°
C to + 85
°
C) and currents
from (60
μ
A to 12mA).
The TCN4041 is available in small SOT-23, TO-92, and
SO-8 packages.
