#129460 - CMOS 7402 , LDO Responding to: ???'s previous message |

The 7402 is being operated at 3.3v, since it is CMOS logic. Is it 74HCMOS, means 74HC02? Brad said:
Also, what do you mean by a tantal on the 3.3 voltage regulator? 3.3V regulators are often LDO (low drop out types), which are intrinsically unstable. They need a certain minimum capacitance (mostly a tantal) connected to the output to become stable. Kai |
