#105915 - low pwr chips Responding to: ???'s previous message |
What is the input voltage to 7805?
9V How did you find that the regulator alone eating 3.2mA? by measuring without load and even on datasheet its written What is the max load current you would derive from the regulator? below 100mA. do u know a good low dropout and low power 5V regulator which is easily available? can u suggest me low power eating 51 derivatives. in place of 89c2051 or 89c4051? bye i will learn slowly how to talk in this forum. |
