LM4132
SOT-23 Precision Low Dropout Voltage Reference
General Description
Features
The LM4132 family of precision voltage references performs n Output initial voltage accuracy 0.05%
comparable to the best laser-trimmed bipolar references, but n Low temperature coefficient 10ppm/˚C
in cost effective CMOS technology. The key to this break n Low Supply Current, 60µA
through is the use of EEPROM registers for correction of n Enable pin allowing a 3µA shutdown mode
curvature, tempco, and accuracy on a CMOS bandgap ar- n 20mA output current
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
maccuracy of references trimmed with laser techniques.
Unlike other LDO references, the LM4132 is capable of
odelivering up to 20mA and does not require an output ca-
pacitor or buffer amplifier. These advantages and the SOT23
.cpackaging are important for space-critical applications.
Series references provide lower power consumption than
shunt references, since they do not have to idle the maxi-
Umum possible load current under no load conditions. This
advantage, the low quiescent current (60µA), and the low
t4dropout voltage (400mV) make the LM4132 ideal for battery-
powered solutions.
The LM4132 is available in five grades (A, B, C, D and E) for
egreater flexibility. The best grade devices (A) have an initial
accuracy of 0.05% with guaranteed temperature coefficient
eof 10ppm/˚C or less, while the lowest grade parts (E) have
han initial accuracy of 0.5% and a tempco of 30ppm/˚C.
n Voltage options 2.048V, 2.5V, 4.096V
n Custom voltage options available (1.8V to 4.096V)
n VIN range of VREF + 400mV to 5.5V @ 10mA
n Stable with low ESR ceramic capacitors
