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. PACKAGE PIN OUT

THERMAL DATA T, ST PACKAGE: Thermal Resistance-Junction to Tab, JT Thermal Resistance-Junction to Ambient, JA Junction Temperature Calculation: TJ = TA + (PD x JA). The JA numbers are guidelines for the thermal performance of the device/pc-board system. All of the above assume no ambient airflow. Maximum Power Calculation:
PD(MAX)= TJ(MAX) - TA(MAX) JA TJ(OC): Maximum recommended junction temperature
3.0C /W 45C /W
TA(OC): Ambient temperature of the application JA(OC/W): Junction-to-junction temperature thermal resistance of the package, and other heat dissipating materials. The maximum power dissipation for a single-output regulator is : PD(MAX) = [(VIN(MAX) - VOUT(NOM))] x IOUT(NOM) + VIN(MAX) x 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 JA = (150 OC - TA)/PD
