Frequently Asked Questions
How is the output voltage of the LM1117ILD-ADJ/NOPB set?
The output voltage of the LM1117ILD-ADJ/NOPB is set by a resistor divider connected between the output, the adjust pin, and ground. The internal reference voltage of 1.25V appears across the lower resistor, and the output voltage is determined by the resistor ratio. This allows the output to be programmed anywhere from 1.25V up to 13.75V, limited by the 15V maximum input and 1.5V minimum input-output differential specification.
What is the dropout voltage of the LM1117ILD-ADJ/NOPB?
The LM1117ILD-ADJ/NOPB has a typical dropout voltage of 1.2V and a maximum of 1.4V at full 800mA load current. This means the input voltage must exceed the desired output voltage by at least 1.4V to guarantee regulation. While not as low as modern LDOs, this characteristic is acceptable in applications powered from 5V, 12V, or higher bus rails.
What is the maximum input voltage and output current of the LM1117ILD-ADJ/NOPB?
The LM1117ILD-ADJ/NOPB accepts input voltages from 2.6V minimum to 15V maximum, making it compatible with a wide range of power supply rails. It delivers up to 800mA continuous output current with proper thermal management. The combination of 15V input tolerance and 800mA output current makes it versatile for bench power supplies, programmable lab references, and multi-rail embedded systems.
What package does the LM1117ILD-ADJ/NOPB use?
The LM1117ILD-ADJ/NOPB is packaged in an 8-pin WSON (Wafer-Scale Outline No-Lead) package with JESD-30 code S-PDSO-N8. The WSON package has a compact footprint with an exposed thermal pad on the bottom for PCB heat spreading. The ILD suffix in the part number specifically identifies this WSON package variant of the LM1117 family, as other variants come in SOT-223 and TO-252 packages.
What are common applications for the LM1117ILD-ADJ/NOPB?
Common applications include programmable voltage regulators for FPGA I/O banks, custom reference voltage generation for ADC and DAC circuits, post-regulation after switching converters for noise-sensitive analog circuits, and adjustable power supplies in test and measurement equipment. The adjustable output and industrial temperature range make it a flexible choice for industrial sensors, embedded computing modules, and communication hardware requiring non-standard supply voltages.
