LM4130 Precision Micropower Low Dropout Voltage Reference
LM4130
Precision Micropower Low Dropout Voltage Reference
General Description
The LM4130 family of precision voltage references performs
comparable to the best laser-trimmed bipolar references, but
in cost effective CMOS technology. Key to this break through
is the use of EEPROM registers for correction of curvature,
tempco, and accuracy on a CMOS bandgap architecture that
allows package level programming to overcome assembly
shift. The shifts in voltage accuracy and tempco during as-
sembly of die into plastic packages limit the accuracy of ref-
erences trimmed with laser techniques.
Unlike other LDO references, the LM4130 requires no output
capacitor. Neither is a buffer amplifier required, even with
loads up to 20mA. These advantages and the SOT23 pack-
aging are important for cost-critical and space-critical appli-
cations.
Series references provide lower power consumption than
shunt references, since they dont have to idle the maximum
possible load current under no load conditions. This advan-
tage, the low quiescent current (75µA), and the low dropout
voltage(275mV) make the LM4130 ideal for battery-powered
solutions.
The LM4130 is available in five grades (A, B, C, D and E) for
greater flexibility. The best grade devices (A) have an initial
accuracy of 0.05% with guaranteed temperature coefficient
of 10ppm/C or less, while the lowest grade parts (E) have
an initial accuracy of 0.5% and a tempco of 30ppm/C.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see Electrical Characteristics. The guar-
anteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
