... PC board space is a premium or fast settling is demanded. Reverse battery protection keeps the reference from conducting current and being damaged. The LT1460-5 is available in the 8-lead MSOP, SO, PDIP and the 3-lead TO-92 packages also available in the SOT-23 package; see separate data sheet LT1460S3-5 (SOT-23) ...

... LT1460-5 ELECTRICAL CHARACTERISTICS The denotes specifications which apply over the specified temperature range. Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: If the part is stored outside of the specified temperature range, the output may shift due to hysteresis. ...

... A load with a 0.01 F load capacitor. Fast Turn- recommended to add a 0 larger input capacitor to the input pin of the LT1460-5. This helps stability with large load currents and speeds up turn-on. The LT1460-5 can start but it is important to limit the dv/dt of the input ...

... F IN Output Accuracy Like all references, either series or shunt, the error budget of the LT1460-5 is made up of primarily three compo- nents: initial accuracy, temperature coefficient and load regulation. Line regulation is neglected because it typically contributes only 30ppm/V, or 150 V for a 1V input change. The LT1460-5 typically shifts less than 0.01% when soldered into a PCB, so this is also neglected (see PC Board Layout section) ...

... LT1460 APPLICATIONS INFORMATION This motion is repeated for a number of cycles and the relative output deviation is noted. The result shown in Figure 7a is for two LT1460S8-5s mounted vertically and Figure 7b is for two LT1460S8-5s mounted horizontally. The parts oriented in Figure 7a impart less stress into the package because stress is absorbed in the leads ...
