LM4130
Precision Micropower Low Dropout Voltage Reference
General Description Features 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 assembly of die into plastic packages limit the accuracy of references 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 packaging are important for cost-critical and space-critical applications.
Series references provide lower power consumption than
shunt references, since they don’t have to idle the maximum
possible load current under no load conditions. This advantage, 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. Small SOT23-5 package
