LT1021C-5

The LT1021C-5 is designed as a precision reference with ultralow drift and noise, extremely good long term stability and almost total immunity to input voltage variations.

LT1021C-5 has nine features. (1)Pin compatible with most bandgap reference applications, including ref 01, ref 02, LM368, MC1400 and MC1404 with greatly improved stability, noise and drift. (2)Ultralow drift: 5ppm/°C max slope. (3)Trimmed output voltage. (4)Operates in series or shunt mode. (5)Output sinks and sources in series mode. (6)Very low noise: <1ppm P-P (0.1Hz to 10Hz). (7)>100dB ripple rejection. (8)Minimum input/output differential of 1V. (9)100% noise tested. Those are all the main features.

Some absolute maximum ratings of LT1021C-5 have been concluded into several points as follow. (1)Its input voltage would be 40V. (2)Its input/output voltage differential would be 35V. (3)Its output-to-ground voltage (shut mode current limit) would be 10V. (4)Its trim pin-to-ground voltage would be Vout for positive and -20V for negative. (5)Its output short-circuit duration would be 10 seconds for Vin=35V and would be indefinite for Vin<=20V. (6)Its operating temperature range would be from 0°C to 70°C for commercial and -40°C to 85°C for industrial and would be from -65°C to 150°C for military. (7)Its storage temperature range would be from -65°C to 150°C. (8)Its lead temperature soldering 10 sec would be 300°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of LT1021C-5 are concluded as follow. (1)Its output voltage would be min 4.9975V and typ 5V and max 5.0025V. (2)Its output voltage temperature coefficient would be typ 3ppm/°C and max 20ppm/°C. (3)Its line regulation would be typ 4ppm/V and max 12ppm/V for Vin<10V and would be typ 2ppm/V and max 6ppm/V for Vin>10V. Its  And so on.
