description  
The TPS790xx family of low-dropout (LDO)  
voltage regulators offers the benefits of  
low-dropout voltage, ultralow-power operation,  
low-output noise, and miniaturized packaging.  
These regulators feature low-dropout voltages  
and ultralow quiescent current compared to  
conventional LDO regulators. An internal resistor,  
in conjunction with an external bypass capacitor,  
creates a low-pass filter to reduce the noise. The

O

TPS79030 exhibits only 56 µV  
of output  
RMS  
voltage noise using 0.01 µF bypass and 10 µF  
output capacitors. Offered in a 5-terminal small  
outline integrated-circuit SOT-23 package, the  
TPS790xx series devices are ideal for  
micropower operations, low output noise, and  
where board space is limited.

FREQUENCY  
The usual PNP pass transistor has been replaced  
by a PMOS pass element. Because the PMOS  
pass element behaves as a low-value resistor, the  
dropout voltage is very low, typically 57 mV at  
50 mA of load current (TPS79030), and is directly  
proportional to the load current. The quiescent  
current is ultralow (17 µA typically) and is stable  
over the entire range of output load current (0 mA  
to 50 mA). Intended for use in portable systems  
such as laptops and cellular phones, the  
ultralow-dropout voltage feature and ultralow-  
power operation result in a significant increase in  
system battery operating life.
