Hello,
I have another question about LDO TPS7A7300 and its pin configurable voltage.
http://www.ti.com/product/tps7a7300
IC has adjustable output voltage with:
- external resistor divider from 0.9V .. 5V or
- voltage settings pins 0.9V .. 3.5V
but we need output voltage 3,65V. It's possible to set it with voltage divider, but it needs >E24 resistor or combination from lower E's
In datasheet @ page 15 is note:
-----------------------------------------------------------------------------------------
Any output voltage setting that is not listed in Table 1 is not covered in the Electrical Characteristics. For output voltages greater than 3.5 V, use a traditional adjustable configuration (see the TRADITIONAL ADJUSTABLE CONFIGURATION section).
-----------------------------------------------------------------------------------------
I connected all settings pins to GND for output voltage 3,65V and I haven't discovered any problems. Why should we use external voltage divider for the output voltage greater than 3,5V?
And another question: Is it possible to combine Traditional adjustable configuration and User Configurable Output Voltage Setting (eg. coarse setting by E12 external resistors and fine setting by connecting pins of LDO to GND)?
