Description

The TPS730xx 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 a small SOT23 package. NanoStar™ packaging gives an ultrasmall footprint as well as an ultralow profile and package weight, making it ideal for portable applications such as handsets and PDAs. 2E.a2c-mhFdecveicreaminic thceapfaacmitiolyr sonstatbhlee,wouithtpuat. smThae TPS730xx family uses an advanced, proprietary BiCMOS fabrication process to ield low dropout voltages (e.g., 120 mV at 200 mA, TPS73030). Each dmesvwiciethaach0ie.0v0e1s-mfaFstbsytpaarts-supcatipmaecsito(ar)ppwrhoixleimcaotneslyum50-ing low quiescent current (170 mA typical). Moreover, when the device is placed in tandby mode, the supply current is reduced to less than 1 A. The TPS73018 exhibits approximately 23 V_RMS of tput voltage noise at 2.8-V output with a 0.01-F bypass capacitor. Applications of TPS730xx with analog components that are oise-sensitive, such as portable RF electronics, benefit from the high PSRR and low-noise features as well as the fast esponse time.
