Precision Micropower Low Dropout Voltage Reference
General DescriptionThe LM4130familyof precision voltage references performs
comparabletothe best laser-trimmed bipolar references,butcost effective CMOStechnology.Keytothis breakthroughtheuseof EEPROM registersfor correctionof curvature,
tempco, andaccuracy ona CMOSbandgaparchitecturethat
allows package level programmingto overcome assembly
shift. The shiftsin voltage accuracyand tempco duringas-
semblyofdieinto plastic packages limitthe accuracyofref-
erences trimmed with laser techniques.
Unlike other LDOreferences, theLM4130requiresno output
capacitor. Neitherisa buffer amplifier required, even with
loadsupto 20mA. These advantagesandthe SOT23 pack-
agingare importantfor cost-criticaland space-critical appli-
cations.
Series references provide lower power consumption than
shunt references, sincethey don’t have toidlethe maximum
possible load current underno load conditions. This advan-
tage,thelow quiescent current (75μA),andthelow dropout
voltage(275mV) makethe LM4130 idealfor battery-powered
solutions.
The LM4130is availableinfive grades (A,B,C,DandE)for
greater flexibility.The best grade devices(A) havean initial
accuracyof 0.05% with guaranteed temperature coefficient 10ppm/˚Cor less, whilethe lowest grade parts(E) have initial accuracyof 0.5%anda tempcoof 30ppm/˚C.
Features Small SOT23-5 package High output voltage accuracy 0.05% Low Temperature Coefficient 10 ppm/˚C Stable with capacitive loadsto 100μF Low dropout voltage ≤275mV@10mA Supply Current ≤75μA Full accuracy −40˚Cto 85˚C Extended operationto 125˚C Excellent loadandline regulation Output current 20mA Output impedance <1Ω Voltage options: 2.048V, 2.500V,and 4.096V
