1 / 15 page  Analog Microelectronics, Inc. 1 AME1117 1A Low Dropout Positive Voltage Regulator n n n n n Typical Application n n n n nGeneral Descriptions The AME1117 is a 1A low-dropout positive voltage regu- lator. It is available in fixed and adjustable output voltage versions. Overcurrent and thermal protection are integrated onto the chip. Output current will limit as while it reaches the pre-set current or temperature limit. The dropout voltage is specified at 1.4V Maxi- mum at full rated output current. The AME1117 series provides excellent regulation over line, load and tem- perature variations. n n n n nApplications l High Efficiency Linear Regulators l 5V to 3.3V Voltage Converter l Battery Charger l Post Regulators for Switching Supplies n n n n nFunctional Block Diagram Figure 1 n n n n nKey Features l Low dropout voltage ..............1.2V at 1A l Adjustable or fixed voltages 2.5V, 3.3V, 5.0V l Typical line regulation ....... 0.2% l Typical load regulation ...... 0.15% l Adjust pin current less than 90µA l Overcurrent protection l Thermal protection l Available in TO-220, TO-252, SOT-223 Input range depends on V OUT Please refer to electrical characteristics.
