I/O Connections
Typical at TA = +25°C under nominal line voltage and full-load conditions, unless noted. All models
are tested/specied with external 22μF tantalum input and output capacitors. These capacitors
are necessary to accommodate our test equipment and may not be required to achieve specied
performance in your applications. See I/O Filtering and Noise Reduction.
Ripple/Noise (R/N) is tested/specied over a 20MHz bandwidth and may be reduced with external
ltering. See I/O Filtering and Noise Reduction for details.
These devices have no minimum-load requirements and will regulate under no-load conditions.
Regulation specications describe the output-voltage deviation as the line voltage or load is varied
from its nominal/midpoint value to either extreme.
Nominal line voltage, no-load/full-load conditions.
VIN = 4.5 Volts minimum for VOUT = 3.3 Volts.
LSM-T/16-W3 specs are given with VOUT = 3.3 Volts, unless noted.
