The LM4132 familyof precision voltage references
performs comparable to the best laser-trimmed
bipolar references, but in cost-effective CMOS
technology. The keyto this breakthroughis the useof
EEPROM registers for correction of curvature,
temperature coefficient (tempco), and accuracy ona
CMOS band-gap architecture allowing package-level
programmingto overcome assembly shift. The shifts voltage accuracy and tempco during assemblyof
die into plastic packages limit the accuracy of
references trimmed with laser techniques.
Unlike other LDO references, the LM4132 can deliverto20 mA and does not requirean output capacitor buffer amplifier. These advantages along with the
SOT-23 packaging are important for space-critical
applications.
Series references provide lower power consumption
than shunt references, because they do not haveto
idle the maximum possible load current under no-load
conditions. This advantage, the low quiescent current
(60 µA), and the low dropout voltage (400 mV) make
the LM4132 idealfor battery-powered solutions.
The LM4132is availablein five grades (A,B, C,D
andE) for greater flexibility. The best grade devices
(A) have an initial accuracyof 0.05% witha specified
temperature coefficientof 10 ppm/°Cor less, while
the lowest grade devices (E) have an initial accuracy 0.5% anda tempcoof30 ppm/°C.
