TPS76830QD

1A低压差3.0V线性稳压器

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

Since 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, because 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 shutdown 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.
