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
GND/HSINK 9
12 GND/HSINK
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.
GND/HSINK 10 11 GND/HSINK
NC − No internal connection
Additionally, since the PMOS pass element is a
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 TJ = 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.
