The power supply operating • Predictable Curvature Error range is 2.4 V to 5.5 V. The transfer function of LM20 is predominately linear, yet has a slight predictable • Suitable for Remote Applications parabolic curvature. The accuracy of the LM20 when • Accuracy at 30°C ±1.5 to ±4°C (Maximum) specified to a parabolic transfer function is ±1.5°C at • Accuracy at 130°C and −55°C ±2.5 to ±5°C an ambient temperature of 30°C. The temperature (Maximum) error increases linearly and reaches a maximum of ±2.5°C at the temperature range extremes. The • Power Supply Voltage Range 2.4 V to 5.5 V temperature range is affected by the power supply • Current Drain 10 μA (Maximum) voltage. At a power supply voltage of 2.7 V to 5.5 V, • Nonlinearity ±0.4% (Typical) the temperature range extremes are 130°C and • Output Impedance 160 Ω (Maximum) −55°C. Decreasing the power supply voltage to 2.4 V changes the negative extreme to −30°C, while the • Load Regulation positive extreme remains at 130°C. 0 μA < IL< 16 μA −2.5 mV (Maximum) The LM20 quiescent current is less than 10 μA. 2 Applications Therefore, self-heating is less than 0.02°C in still air. Shutdown capability for the LM20 is intrinsic because • Cellular Phones its inherent low power consumption allows it to be • Computers powered directly from the output of many logic gates or does not necessitate shutdown. • Power Supply Modules • Battery Management Device Information(1) • FAX Machines PART NUMBER PACKAGE BODY SIZE (NOM) • Printers SC70 (5) 2.00 mm × 1.25 mm LM20 • HVAC DSBGA (4) 0.96 mm × 0.96 mm • Disk Drives (1) For all available packages, see the orderable addendum at • Appliances the end of the data sheet.
