The 2-pin fixed-output device • Tight Output Tolerances and Low Temperature requires no external capacitors for operation and is Coefficient stable with all capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, – Max 0.1%, 100 ppm/°C – A Grade and low temperature coefficient to ensure a stable – Max 0.2%, 100 ppm/°C – B Grade output voltage over a wide range of operating – Max 0.5%, 100 ppm/°C – C Grade currents and temperatures. The LM4040 uses fuse – Max 1.0%, 150 ppm/°C – D Grade and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, • Low Output Noise: 35 μVRMS Typ ranging from 0.1% (max) for the A grade to 1% (max) • Wide Operating Current Range: 45 μA Typ to 15 for the D grade. Thus, a great deal of flexibility is mA offered to designers in choosing the best cost-to- • Stable With All Capacitive Loads; No Output performance ratio for their applications. Capacitor Required Packaged in space-saving SC-70 and SOT-23-3 • Available in Extended Temperature Range: –40°C packages and requiring a minimum current of 45 μA to 125°C (typ), the LM4040 also is ideal for portable applications. The LM4040xI is characterized for operation over an ambient temperature range of 2 Applications –40°C to 85°C. The LM4040xQ is characterized for • Data-Acquisition Systems operation over an ambient temperature range of • Power Supplies and Power-Supply Monitors –40°C to 125°C. • Instrumentation and Test Equipment Device Information(1) • Process Controls PART NUMBER PACKAGE (PIN) BODY SIZE (NOM) • Precision Audio SOT-23 (3) 2.92 mm × 1.30 mm • Automotive Electronics LM4040xxx SC70 (6) 2.00 mm × 1.25 mm • Energy Management (1) For all available packages, see the orderable addendum at • Battery-Powered Equipment the end of the data sheet. 4 Simplified Schematic 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
