LM317-N 的說明

The LM117 and LM317-N series of adjustable 3-pin positive voltage regulators are capable of supplying in excess of 1.5 A over a 1.25-V to 37-V output range and a wide temperature range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators.

The LM117 and LM317-N offer full overload protection such as current limit, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected.

Typically, no capacitors are needed unless the device is situated more than 6 inches from the input filter capacitors, in which case an input bypass is needed. An optional output capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple rejection ratios that are difficult to achieve with standard 3-terminal regulators.

Because the regulator is floating and detects only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input-to-output differential is not exceeded. That is, avoid short-circuiting the output.

By connecting a fixed resistor between the adjustment pin and output, the LM117 and LM317-N can be also used as a precision current regulator. Supplies with electronic shutdown can be achieved by clamping the adjustment terminal to ground, which programs the output to 1.25 V where most loads draw little current.

For applications requiring greater output current, see the LM150 series (3 A) and LM138 series (5 A) data sheets. For the negative complement, see the LM137 series data sheet.

包裝類型選項

您可依零件數量選擇不同包裝類型選項,包含完整捲盤、客製化捲盤、剪切捲帶、承載管或盤。

客製化捲盤是從一個捲盤上剪切下來的連續剪切捲帶,以維持批次和日期代碼可追溯性,依要求剪切至確切數量。依照業界標準,銅墊片會在剪切捲帶兩側連接 18 英吋前後導帶,以直接送至自動組裝機器。針對客製化捲盤訂單,TI 將酌收捲帶封裝費用。

剪切捲帶是從捲盤剪切下來的一段捲帶。TI 可能使用多條剪切捲帶或承載盒,以滿足訂單要求數量。

TI 常以盒裝或管裝、盤裝方式運送承載管裝置,視現有庫存而定。所有捲帶、管或樣本盒之封裝,皆符合公司內部靜電放電與防潮保護包裝要求。
