RT9161/A is a 300/500mA fixed output voltage low dropout linear regulator. Typical ground current is approximately 110μA, from zero to maximum loading conditions. Wide range of available output voltage fits most of applications. Built-in output current-limiting and thermal-limiting provide maximal protection against any fault conditions. For ease of application, the RT9161/A comes in the popular 3-pin SOT-23 (300mA), SOT-89 (300mA), SOT-223 (500mA), or TO-92 packages. Applications include voltage regulators for LAN Card, CD-ROM, and DVD, wireless communication systems, and battery powered systems.
