LM4132
SOT-23 Precision Low Dropout Voltage Reference
General Description
The LM4132 family of precision voltage references performs
comparable to the best laser-trimmed bipolar references, but
in cost effective CMOS technology. The key to this break
through is the use of EEPROM registers for correction of
curvature, tempco, and accuracy on a CMOS bandgap ar-
chitecture that allows package level programming to over-
come assembly shift. The shifts in voltage accuracy and
tempco during assembly of die into plastic packages limit the
accuracy of references trimmed with laser techniques.
Unlike other LDO references, the LM4132 is capable of
delivering up to 20mA and does not require an output ca-
pacitor or buffer amplifier. These advantages and the SOT23
packaging are important for space-critical applications.
Series references provide lower power consumption than
shunt references, since they do not have to idle the maxi-
mum possible load current under no load conditions. This
advantage, the low quiescent current (60µA), and the low
dropout voltage (400mV) make the LM4132 ideal for battery-
powered solutions.
The LM4132 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.
