Part Details:

LM4120 March 2005 Precision LM4120Precision Micropower Low Dropout Voltage ReferenceGeneral Description Features The LM4120 is a precision low power low dropout bandgap n Small SOT23-5 package Micropower voltage reference with up to 5 mA output current source and n Low dropout voltage: 120 mV Typ @ 1 mA sink capability. n High output voltage accuracy: 0.2% This series reference operates with input voltages as low as n Source and Sink current output: ±5 mA 2V and up to 12V consuming 160 µA (Typ.) supply current. In n Supply current: 160 µA Typ. power down mode, device current drops to less than 2 µA. n Low Temperature Coefficient: 50 ppm/°C The LM4120 comes in two grades (A and Standard) and n Enable pin seven voltage options for greater flexibility. The best grade n Fixed output voltages: 1.8, 2.048, 2.5, 3.0, 3.3, 4.096 devices (A) have an initial accuracy of 0.2%, while the stan- and 5.0V Low dard have an initial accuracy of 0.5%, both with a tempco of n Industrial temperature Range: -40°C to +85°C 50ppm/°C guaranteed from -40°C to +125°C. n (For extended temperature range, -40°C to 125°C, The very low dropout voltage, low supply current and power- contact National Semiconductor) down capability of the LM4120 makes this product an ideal Dropout choice for battery powered and portable applications. Applications The device performance is guaranteed over the industrial n Portable, battery powered equipment temperature range (-40°C to +85°C), while certain specs areguaranteed over the extended temperature range (-40°C to n Instrumentation and process control +125°C). Please contact National for full specifications over n Automotive & Industrial the extended temperature range. The LM4120 is available in V n Test equipment oltage a standard 5-pin SOT-23 package. n Data acquisition systems n Precision regulators
