AMC317

AMC317 www.addmtek.com DESCRIPTION The AMC317 series is a 3-terminal adjustable regulator featuring output current of typical 1.2A over a wide output range from 1.2V to 20V. Only two external resistors are required to set the output voltage. This feature provides better line and load regulation than fixed regulators. Also, the AMC317 series offers full overload protection, current limit, and thermal protection features. In most applications, no capacitor is required for the AMC317. However, if the device is located far from the input filter capacitor, then an input bypass will be required. Also, in order to improve the transient response, an output capacitor is recommended. 1.2A / 3-TERMINAL ADJUSTABLE REGULATOR FEATURES Output current capability of 1.2A Wide output voltage range – adjustable from 1.2V to 20V Ripple rejection typically 80 dB Typically 0.1% load regulation Built-in over current, over temperature and overload protection. Internal thermal overload protection Available in 3-Lead TO-220, and surface mount 3-Lead TO-263. Identical pin assignment to earlier LM317 series.

The maximum power dissipation for a single-output regulator is : PD(MAX) = [(VIN(MAX) - VOUT(NOM))] × IOUT(NOM) + VIN(MAX) × IQ Where: VOUT(NOM) = the nominal output voltage IOUT(NOM) = the nominal output current, and IQ = the quiescent current the regulator consumes at IOUT(MAX) VIN(MAX) = the maximum input voltage Then θJA = (150 OC – TA)/PD Copyright © 2006 ADDtek Corp. 2 DD011_G -- MARCH 2007 AMC317 RECOMMENDED OPERATING CONDITIONS Recommended Operating Parameter Symbol Min.
