1 A Low Dropout Positive Voltage Regulator LD1117A 1A Low Dropout Positive Voltage Regulator General Description • LD1117A is a three terminal low dropout positive voltage regulator with a dropout of 1.15V at 1A output current. SOT-223 • LD1117A is available in an adjustable version which can set the output voltage 1.25V to 12V with only 2 external resisitors.In addition,it is also available in 7 Fixed output voltages: 1.2V,1.5V,1.8V,2.5V,2.85V,3.3V an 5.0V SOT-89 • LD1117A provides current limiting and thermal shutdown. Its circuit includes a trimmed Bandgap reference to assure output voltage accuracy to be within ±1.0% for fixed output voltage version and ±2.0% for adjustable output voltage version. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal shutdown provides protection against any combination of overload and ambient temperature TO-220 that would create excessive junction temperature • LD1117A series are available in SOT-223 ,SOT-89 ,TO-220,DPAK (TO-252) and D2PAK (TO-263-3) Packages Features • • • • • • Input Voltage up to 20V Output Current up to 1A Low Drop Output Voltage:Typical 1.15V at 1A output current Trimmed Current Limit and On-Chip Thermal Shutdown Operation Junction Temperature: -40°C to 125°C RoHS Compliance and Halogen Free DPAK （TO-252） D2PAK （TO-263-3） Applications • • • • PC Mother Board Graphic Card NIC/Switch LCD Monitor , DVD Video Player and Printer • Telecom Equipment and other Peripheral Equipment TAITRON COMPONENTS INCORPORATED www.taitroncomponents.com Tel: Fax: (800)-TAITRON (800)-824-8766 (800)-TAITFAX (800)-824-8329 (661)-257-6060 (661)-257-6415 Rev.

Recommend operating ratings indicate conditions for which the device is functional, but do not guarantee specific specification limits. For guarantee specification and test conditions, see the Electrical Characteristics, the guarantee specification apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Note2: The Max power dissipation is a function of TJ(max), θJA and TA .The maximum allowable power dissipation at any temperature is PD(Max)=(TJ(max)-TA)/ θJA, Exceeding the maximum allowable power dissipation will result in die temperature and the Regulator will go into thermal shutdown Rev.
