TPS79330) - 5- and 6-Pin SOT23 (DBV) and NanoStar Wafer
Chip Scale (YZQ) Packages
The TPS793 family of low-dropout (LDO) low-power linear voltage regulators features high power-supply rejection ratio (PSRR), ultralow-noise, fast start-up, and excellent line and load transient responses in NanoStar™ wafer chip scale and SOT23 packages. NanoStar packaging gives an ultrasmall footprint as well as an ultralow profile and package weight, making these devices ideal for portable applications such as handsets and PDAs. Each device in the family is stable, with a small, 2.2-µF ceramic capacitor on the output. The TPS793 family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example, 112 mV at 200 mA, TPS79330). Each device achieves fast start-up times (approximately 50 µs with a 0.001-µF bypass capacitor) while consuming very low quiescent current (170 µA typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1 µA. The TPS79328 exhibits approximately 32 µVRMS of output voltage noise at 2.8-V output with a 0.1-µF bypass capacitor. Applications with analog components that are noise-sensitive, such as portable RF electronics, benefit from the high PSRR and low-noise features as well as the fast response time.
