2 Description
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 TPS76750)
and is directly proportional to the output current.
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 1 µA at T_J = 25°C.
