AME8817

Analog Microelectronics, Inc. AME8817 INARY PRELIM 1.5A CMOS LDO n General Description The AME8817 family of positive, linear regulators feature low quiescent current (35µA typ.) with low dropout voltage, making them ideal for battery applications. Output voltages are set at the factory and trimmed to 1.5% accuracy. These rugged devices have both thermal shutdown, and current fold-back to prevent device failure under the "worst" of operating conditions. In applications requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and Ground. An additional feature is a "Power Good" detector, which pulls low when the output is out of regulation. The AME8817 is stable with an output capacitance of 4.7µF or greater. n Features l l l l l l l l l l l Very Low Dropout Voltage Guaranteed 1.5A Output Accurate to within 1.5% 35µA Quiescent Current Typically Over-Temperature Shutdown Current Limiting Short Circuit Current Fold-back Noise Reduction Bypass Capacitor Power Good Output Power-Saving Shutdown Mode Space-Saving DDPAK-7 Package l Low Temperature Coefficient n Applications l l l l l n Functional Block Diagram IN OUT Instrumentation Portable Electronics Wireless Devices PC Peripherals Battery Powered Widgets Overcurrent Shutdown Thermal Shutdown n Typical Application R1 IN BYP (or ADJ) IN BYP GND OUT OUT AME8817 P G EN AMP PG EN C1 5V C2 C3 1 µF 1nF 4.7 µF 1.24V R2 GND 1 Analog Microelectronics, Inc.
