| 100mA Adjustable Positive Voltage Regulator LA317L 100mA Adustable Positive Voltage Regulator General Description * The LA317L is an adjustable 3-terminal positive voltage regulator capable of supplying 100mA over a 1.2V to 12V output range. This voltage regulator is exceptionally easy to use and requires only tow external resistors to set the output voltage. * The LA317L is available in standard TO-92 and SOP-8 packages. TO-92 SOP-8 Features * * * * * * * * * Adjustable output down to 1.2V Guaranteed 100mA output current Output short circuit protected Line regulation: 0.01%/V Load regulation: 0.1% Constant current limit over temperature Standard 3-lead transistor package Input ripple rejection: 70dB RoHS Compliance Applications * * * * High Efficiency Linear Regulators Post Regulation for Switching Supplies Microprocessor Power Supply Mother Board I/O Power Supply Ordering Information 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.
