This device is designed to have a fast transient  
response and be stable with 10-µF low ESR  
capacitors. This combination provides high  
performance at a reasonable cost.

Because the PMOS device behaves as a low-value  
resistor, the dropout voltage is very low (typically 230  
mV at an output current of 1 A for the TPS76850) and  
is directly proportional to the output current.  
Additionally, since the PMOS pass element is a  
GND/HSINK  
GND/HSINK  
GND/HSINK  
GND/HSINK  
NC − No internal connection  
voltage-driven device, the quiescent current is very low and independent of output loading (typically 85 µA over  
the full range of output current, 0 mA to 1 A). These two key specifications yield a significant improvement in  
operating life for battery-powered systems. This LDO family also features a sleep mode; applying a TTL high  
signal to EN (enable) shuts down the regulator, reducing the quiescent current to less than 1 µA at T = 25°C.

Power good (PG) is an active high output, which can be used to implement a power-on reset or a low-battery  
indicator.  
The TPS768xx is offered in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V, and 5.0-V fixed-voltage versions and  
in an adjustable version (programmable over the range of 1.2 V to 5.5 V). Output voltage tolerance is specified  
as a maximum of 2% over line, load, and temperature ranges. The TPS768xx family is available in a 20-pin PWP  
package.
