GENERAL DESCRIPTION
For applications in tight quarters, the TCN4040 preci-
sion voltage reference is available in a space-saving
3mm x 1.3mm SOT-23B-3 surface mount package. The
TCN4040 eliminates the need for an external stabilizing
capacitor while maintaining stability with any capacitive
load. The minimum operating current is 60µA. The maxi-
mum operating current is 15mA.
To ensure that the prime parts have an accuracy of
better than ±0.5% (C grade) at 25°C, the TCN4040 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 (60µA to 15mA).
The TCN4040 also is available in both adjustable and
1.2V versions.
