Are there any LDO regulators with adjustable output voltage available (requiring external resistors)?

Our product lineup includes LDO regulators that allow output voltage (VOUT) to be adjusted via external resistors.

To view the lineup of LDO regulators with adjustable output voltage, click the link shown below.

VOUT is calculated

These LDO regulators allow the output voltage to be adjusted via two resistors connected between VOUT and GND so that the voltage between the two resistors is applied to the VADJ pin.

VOUT is calculated as follows:

Typical external resistor values are shown in the datasheet for each LDO regulator. You may want to connect high-value resistors to reduce power consumption, but resistors whose values are too high might cause the LDO regulator to function incorrectly. Care should be exercised during design and evaluation processes to ensure that your LDO regulator works with the resistors selected.
