General Description
The LM1558 and the LM1458 are general purpose dual operational amplifiers. The two amplifiers share a common bias network and power supply leads. Otherwise, their operation is completely independent.
The LM1458 is identical to the LM1558 except that the LM1458 has its specifications guaranteed over the temperature range from 0˚C to +70˚C instead of −55˚C to +125˚C.

Components within dashed lines protect regulator IC from over current condition frequently encountered when zener-SCR crowbar is used across output.Regulated output is 5 V with IC shown. Article gives operating details of circuit and equation for shutdown time, which is about 1 s.-S. J.
