explain
Tps784-q1 ultra low voltage drop regulator (LDO) is a small low static current LDO, which can provide 300mA current and has excellent line and load transient performance. With low output noise and excellent PSRR performance, the device is suitable for powering sensitive analog loads. Tps784-q1 has an input voltage range of 1.65v to 6.0V and an adjustable output voltage range of 1.2V to 5.5V. It is a flexible post regulator. It also provides a fixed output voltage of 0.65v to 5.0V to power the common voltage rail.
Tps784-q1 has turn back current limitation, which can reduce power dissipation under overcurrent conditions. The input of en terminal is helpful to meet the power supply timing requirements of the system
Please. The internal soft start reduces the surge current by controlling the start-up process, thereby reducing the input capacitance used.
Tps784-q1 provides an active pull-down circuit, which can quickly discharge the output load when disabled.
