Voltage regulator Comparison

[spike47]

Hi

I am trying to find a equivelant to this regulator MCP1700-2102E/TO from Microchip technology , I need 2.1 Volts output in a 3-Pin TO-92 package.
There seems to be plenty of 1.8 v and 3.3v around ! .

attached data sheet

Hi

Thanks for your reply , could not find any there , I have found a data sheet for one but it is a old data sheet by TelCom semiconducter inc , who are now Micochip , back were I started ! .

cheers

hi,
The closest I can find is the Holtek TO92 2.1v, most of the 2.1v are custom devices.

Does it have to be TO-92? If your more flexible on that requirement you will have better luck finding a similar part that is adjustable. For example:

https://www.mouser.com/ds/2/268/22070a-53890.pdf
The MCP1824/MCP1824S is a 300 mA Low Dropout
(LDO) linear regulator that provides high current and
low output voltages. The MCP1824 comes in a fixed or
adjustable output voltage version, with an output
voltage range of 0.8V to 5.0V. The 300 mA output
current capability, combined with the low output voltage
capability, make the MCP1824 a good choice for new
sub-1.8V output voltage LDO applications that have
high current demands. The MCP1824S is a 3-pin fixed
voltage version.
Also take a look at this selection Matrix:

I'm afraid if you stick with your TO-92 requirement, your gonna limit your choices. Party on

Hi

Thanks for your reply , yes I do need them to be in a 3-Pin TO-92 package , but ericgibbs as found some for me in a TO-92 package , just hope that they are available .

When I've had similar issues where I have to replace a custom-voltage three terminal regulator......................I build a small board with the regulator IC which can provide me with the proper voltage and its associated components, and have a three pin header coming out of it with the same pin configuration as the older regulator.
If done with SMT components, you can make it fit.
