12VIN
External capacitor input used to filter the internal supply rail.
12V power supply input internally regulated to 3.6 or 5.5V. Input range is 6V to
14V using the 3.6V internal regulator setting and 10V to 14V using the 5.5V
internal regulator setting.
2.7V to 5.5V Power supply of the part.
Ground of the part.
External sample and hold capacitor input used to set the voltage on the TRIM
pins.
Output voltage used to margin and/or trim converter voltages. Connect to the
converter Trim input or to the VADJ or FB pin of an adjustable output switching
regulator or LDO through a resistor.
