Frequently Asked Questions
What is the output voltage range of the LM1086CT-ADJ and how is it set?
The LM1086CT-ADJ provides an adjustable output voltage from 1.2V to 15V, set by a resistor divider network connected between the output pin, the ADJ pin, and ground. Selecting appropriate resistor values using the standard LDO adjustment formula (V_out = 1.25 times (1 + R2/R1)) allows the user to precisely program any target voltage within the 1.2V to 15V range for their specific application requirements.
What is the maximum output current and dropout voltage of the LM1086CT-ADJ?
The LM1086CT-ADJ can deliver a maximum output current of 1.5A with a nominal dropout voltage of 1.3V (1.5V maximum). This means the input supply must be at least 1.3V to 1.5V higher than the desired output voltage to maintain regulation. For example, to regulate a 3.3V output, the input must be at least 4.6V, making it suitable for 5V-to-3.3V regulation with minimal power dissipation.
What package does the LM1086CT-ADJ come in?
The LM1086CT-ADJ is housed in a TO-263 3-pin surface-mount package, JESD-30 code R-PSFM-T3. The TO-263 provides a large thermal tab that can be soldered directly to a PCB copper pad, enabling efficient heat transfer without a bulky external heatsink. This surface-mount variant is preferred in modern automated PCB assembly for applications requiring high output current up to 1.5A.
Is the LM1086CT-ADJ suitable as a post-regulator for switching power supplies?
Yes, the LM1086CT-ADJ is commonly used as a low-noise post-regulator following a switching converter to clean up output ripple and provide adjustable fine voltage control. The LDO analog regulation characteristic filters switching noise of an upstream DC-DC converter, making it ideal for sensitive analog, RF, and precision measurement circuits that require quiet, low-ripple power supply rails at up to 1.5A.
