Product Summary

The TPS71733DCKR is a low-dropout(LDO), low-power linear regulator offers very high power supply rejection (PSRR) while maintaining very low 50μA ground current in an ultra-small, five-pin SC70-Fixed Output with Voltages from 0.9V topackage. The family uses an advanced BiCMOS process and a PMOSFET pass device to achieve fast start-up, very low noise, excellent transient response, and excellent PSRR performance. The applications of the TPS71733DCKR include Mobile Phone Handsets, Wireless LAN, Bluetooth, PDAs and Smartphones.
