Precision Micropower Low Dropout Voltage Reference
LM4120
Precision Micropower Low Dropout V oltage Reference
General DescriptionThe LM4120isa precision low power low dropout bandgap
voltage reference withupto5 mA output current source and
sink capability.
This series reference operates with input voltagesas lowas andupto 12V consuming 160μA (Typ.) supply current.In
power down mode, device current dropsto less than2 μA.
The LM4120 comesin two grades(A and Standard) and
seven voltage optionsfor greater flexibility. The best grade
devices(A) havean initial accuracyof 0.2%, while the stan-
dard havean initial accuracyof 0.5%, both witha tempcoof
50ppm/˚C guaranteed from −40˚Cto +125˚C.
The very low dropout voltage, low supply current and
power-down capabilityofthe LM4120 makes this productan
ideal choicefor battery powered and portable applications.
The device performanceis guaranteed over the industrial
temperature range (−40˚Cto +85˚C), while certain specs are
guaranteed over the extended temperature range (−40˚Cto
+125˚C). Please contact Nationalforfull specifications over
the extended temperature range. The LM4120is availablein standard 5-pin SOT-23 package.
Features Small SOT23-5 package Low dropout voltage: 120 mV Typ@ 1mA High output voltage accuracy: 0.2% Source and Sink current output: ±5mA Supply current: 160μA Typ. Low Temperature Coefficient: 50 ppm/˚C Enablepin Fixed output voltages: 1.8, 2.048, 2.5, 3.0, 3.3, 4.096
and 5.0V Industrial temperature Range: −40˚Cto +85˚C (For extended temperature range, −40˚Cto 125˚C,
