AME1300BEQA300

AME AME1300 n General Description The AME1300 combines a Low Dropout Regulator and a Microprocessor Reset Monitor in a space-saving MSOP8 package. Total supply current is 50µA (typical), 20 to 60 times lower than in bipolar regulators . The AME1300 has an extremely precise output with a typical accuracy of ±1.5%. Other key features include ultra low noise operation, very low dropout voltage and internal feed-forward compensation for fast response to step changes in load. The AME1300 incorporates both over-temperature and over-current protection. When the shutdown control EN is low, the regulator output voltage falls to zero, RESETB output remains valid and supply current is reduced to 10µA(typical). The AME1300 is stable with an output capacitor of only 2.2µF and has a minimum output current of 300 mA. An active low RESET is asserted when the detected voltage (V DET) falls below the reset voltage threshold. The reset output remains low for 300msec(typical) after VDET rises above reset threshold. The AME1300 also has a fast wake up response time (10µsec typically) when released from shutdown. 470pF 300mA CMOS LDO with RESET Function n Applications l Instrumentation l Portable Electronics l Wireless Devices l Cellular / GSM / CDMA Phones l PC Peripherals l Battery Powered Widgets n Typical Applications RESETB RESETB VDET VDET V DET and VOUT can be connected together VOUT OUT IN VIN GND 1300 NC BYP EN SHUTDOWN CONTROL CBypass (Option) n Features l LDO with intergrated Microprocessor Reset Monitor Functionality l Guaranteed 300mA Output l Accurate to within 1.5% l 50µA Quiescent Current l Over-Temperature Shutdown l Current Limiting l Short Circuit Current Fold-back l Noise Reduction Bypass Capacitor l Power-Saving Shutdown Mode l Space-Saving MSOP Package l Factory Pre-set Output Voltages l Low Temperature Coefficient l All AME's Lead Free Products Meet RoHS Standards. 1 2 3 4 8 n Pin Configuration MSOP-8 Top View 7 6 5 AME1300 1.
