Frequently Asked Questions
What output voltage range can the TL317P regulate, and how is it set?
The TL317P adjusts its output from 1.25 V to 32 V using two external resistors connected between the output, adjust, and ground pins. The output voltage is set by the ratio of these two resistors, making it easy to target any voltage within the 1.25 V to 32 V range for a given design.
How much output current can the TL317P continuously supply in a typical circuit?
The TL317P can supply up to 100 mA of continuous output current, making it suitable for low-power regulated supply rails, bias circuits, and small signal loads where current demand stays below 100 mA.
In which package does the TL317P come, and what board footprint should designers plan for?
The TL317P is packaged in a TO-92 style plastic package with 3 pins occupying roughly 5 mm × 5 mm of board area. Designers should plan for a through-hole footprint with 1.27 mm lead spacing, and include adequate copper area for thermal dissipation at elevated currents approaching 100 mA.
When would the TL317P be a suitable lower-current alternative to the LM317?
The TL317P is a practical alternative to the LM317 in applications needing less than 100 mA output current, such as bias rails for op-amp circuits or small logic supply regulators. Its smaller package reduces board space by over 50 % compared to the LM317 in TO-220, and both share the same 1.25 V to 32 V adjustable output range.
