3 Description

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).
