FEATURES  
DESCRIPTION  
•
250-mA Low-Dropout Regulator With Enable  
The TPS794xx family of low-dropout (LDO) linear  
voltage regulators features high power-supply  
rejection ratio (PSRR), ultralow-noise, fast start-up,  
and excellent line and load transient responses in  
small outline, MSOP-8 PowerPAD™ and SOT223-6  
packages. Each device in the family is stable with a  
small 2.2-µF ceramic capacitor on the output. The  
family uses an advanced, proprietary BiCMOS  
fabrication process to yield extremely low dropout  
voltages (for example, 155 mV at 250 mA). Each  
device achieves fast start-up times (approximately  
50 µs with a 0.001-µF bypass capacitor) while  
consuming low quiescent current (170 µA typical).  
Moreover, when the device is placed in standby  
mode, the supply current is reduced to less than

time.
