Product Overview
The RT9161-28GV from Richtek is a 300mA fixed output voltage low dropout linear voltage regulator in 3 pin SOT-23 package. 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. Typical applications includes voltage regulator for LAN card, CD-ROM and DVD, battery powered systems and motherboard.
- Output voltage is 2.8V
- Internal 1.5ohm P-MOSFET draws no base current
- Low dropout voltage is 450mV at 0.3A
- 2% accuracy output voltage
- Input voltage range from 4.5V to 12V
