AS116 Low Dropout Voltage Three Terminal Regulator FEATURES APPLICATIONS • 3.5V, 3.3V, 3.0V and AdjustableVersions Available • Very Low Dropout Voltage • Output Current In Excess Of 100mA • Low Standby Current (ON, No Load) • Short Circuit Protection • Internal Thermal Shutdown • Available in TO-92, SO-8 & SO-89 Packages • Direct Replacement Pin to Pin to TK116 • Battery Powered Systems • Cordless Telephones • Radio Control Systems • Portable/ Palm Top / Notebook Computers • Portable Consumer Equipment • Portable Instrumentation • Pager • Low Voltage Systems • Cellular Phone PRODUCT DESCRIPTION The AS116 is a low power voltage regulators. This devices are an excellent choice for use in battery-powered applications such as cordless telephones, radio control systems, and pagers. The AS116 features very low quiescent current in ON (400µA no load and 2mA at 60mA load) and OFF mode and very low dropout voltage of less than 200mV at 80mA load through internal PNP passtransistor. The junction temperature of 150°C is achieved through an internal thermal shutdown. In case of short circuit, the AS116 will shut down. This device is available in 3.0V, 3.3V and 3.5V output voltages. This regulator is available in TO-92, SO-8 and SOT-89 packages, it can also be supplied in tape and reel. The AS116 is a direct replacement to TK116. ORDERING INFORMATION TO-92 SO-8 SOT-89 3-PIN Oper. Temp. Range AS116N-XX AS116S-XX AS116M1-XX IND.
