The space-saving SOT-23-6 package is attractive for "Pocket" and "Hand Held" applications. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the "Worst" of operating conditions. An additional feature is a "Power Good" detector, which pulls low when the output is out of regulation. In appli- cations requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and ground. The AME8803 is stable with an output capacitance of 2.2 µF or greater. n n n n n Applications l Instrumentation l Portable Electronics l Wireless Devices l Cordless Phones l PC Peripherals l Battery Powered Widgets l Electronic Scales AMP GND OUT IN R1 R2 PG Overcurrent Shutdown Thermal Shutdown EN V ref=1.215V V ref x90% V ref x110% BYP AME8803 OUT IN C3 2.2 µF C1 1 µF GND OUT 5V PG BYP IN C2 1nF EN |
