8.3.4 Pin-Selectable Output Voltage (DEF)

The output voltage of the TLV62130 devices can be increased by 5% above the nominal voltage by setting the DEF pin to High (1). When DEF is Low, the device regulates to the nominal output voltage. Increasing the nominal voltage allows adapting the power supply voltage to the variations of the application hardware. More detailed information on voltage margining using TLV62130 can be found in SLVA489. A pull down resistor of about 400 kΩ is internally connected to the pin, to ensure a proper logic level if the pin is high impedance or floating after initially set to Low. The resistor is disconnected if the pin is set High.

1. Maximum allowed voltage is 7 V. Therefore, TI recommends connecting it to VOUT or PG, not VIN.
