RT9161/A
300/500mA Low Dropout Linear Voltage Regulator
General Description
The 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 most thermal-limiting provide maximal protection against any fault conditions. For ease of application, the RT9161/A comes in the popular 3-pin SOT-89 (300mA), SOT-223 (500mA), or TO-92 packages.
Features
Low Dropout Voltage of 200mV at Output Current 100mA, 450mV at Output Current 300mA, and 750mV at 500mA Output Current Guaranteed 300/500mA Output Current Internal 1.5 P-MOSFET Draws No Base Current Low Ground Current 110µA 2% Accuracy Output Voltage Input Voltage Range up to 12V Extremely Tight Load Regulation Fast Transient Response Current-limiting and Thermal-limiting
Applications
Voltage Regulator for LAN Card, CD-ROM, and DVD Wireless Communication Systems Battery Powered Systems

Note: (1) Guaranteed by design. (2) Regulation is measured at constant junction temperature, using pulsed ON time. (3) Current Limit is measured at constant junction temperature, using pulsed ON time. (4) Dropout is measured at constant junction temperature, using pulsed ON time, and the criterion is VOUT inside target value ± 2%. (5) Dropout test is skipped at the condition of VIN < 3V.
