3.3-V, 4.75-V, and Adjustable High PSRR (70 dB at 10 kHz) Ultralow Noise (32 µV) Fast Start-Up Time (50 µs) Stable With a 2.2-µF Ceramic Capacitor Excellent Load/Line Transient Very Low Dropout Voltage (112 mV at Full Load, TPS79330) 5-Pin SOT23 (DBV) Package
DESCRIPTION
The TPS793xx 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 a small outline, SOT23, package. Each device in the family is stable, with a small 2.2-µF ceramic capacitor on the output. The TPS793xx family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (e.g., 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 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.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: All voltage values are with respect to network ground terminal.

NOTES: 2. To calculate the minimum input voltage for your maximum output current, use the following formula: VI(min) = VO(max) + VDO (max load) 3. Continuous output current and operating junction temperature are limited by internal protection circuitry, but it is not recommended that the device operate under conditions beyond those specified in this table for extended periods of time. 4. The minimum IN operating voltage is 2.7 V or VO(typ) + 1 V, whichever is greater. The maximum IN voltage is 5.5 V. The maximum output current is 200 mA. 5. If VO 2.5 V then VImin = 2.7 V, VImax = 5.5 V: 00 If VO 2.5 V then VImin = VO + 1 V, VImax = 5.5 V. Line Reg. (mV) + % V V O
