LM4132

SOT-23 Precision Low Dropout Voltage Reference

General Description

Features

n Output initial voltage accuracy 0.05%

n Low temperature coefficient 10ppm/˚C

n Low Supply Current, 60µA

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.

n Enable pin allowing a 3µA shutdown mode

n 20mA output current

n Voltage options 1.8V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V

n Custom voltage options available (1.8V to 4.096V)

n V_INrange of V_REF+ 400mV to 5.5V 10mA

n Stable with low ESR ceramic capacitors

n SOT23-5 Package

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.

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.

n Battery Chargers

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.

is optional.
