Technical content

Features

  • High Accurate * Over-Temperature Shutdown ± 1.5% * Very Low Dropout Voltage * Low Temperature Coefficient * Short Circuit Current Fold-back * Guaranteed 300mA output * Current Limiting * Portable Electronics

Applications

  • PC Peripherals * Wireless Devices * Battery Powered Widgets * Electronic Scales * Instrumentation * Cordless Phones for battery applications. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the "Worst" of operating conditions. The S2123 is stable with an output capacitance of 2.2µF or greater. 01-Jun-2002 Rev.
