Hello I'm Hidetoshi Matsunami,

I would like to ask 2 questions for TLV1117-18IDCYR.

1. TLV1117-18IDCYR has two Vout-pins.

What's the difference between Vout-pins?

Also will the noise performance change if either one Vout-pin connects to ceramic capacitor or gets closer the output?

2. Could you tell me the recommend layout of TLV1117-18IDCYR?

Hidetoshi-san,

1) The "two" VOUT pins are the same sheet of metal. Therefore either or both can be used for electrical connection.

2) The TLV1117 is not compatible with low ESR ceramic capacitors, see application information on page 11 of the data sheet. A series resistor is need to support ceramic capacitors

This device is designed to be stable with tantalum and aluminum electrolytic output capacitors having an ESR
between 0.2 Ohm and 10 Ohm.
