TPS76833QPWPRQ1 General Description

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.

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-Q1) 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 the enable (EN) input shuts down the regulator, reducing the quiescent current to less than 1 µA at T_J = 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-Q1 is offered in 1.8-V, 2.5-V, 3.3-V, and 5-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-Q1 family is available in a 20-pin PWP package.

Looks great. Arrived well packaged and very quickly. I have not had a chance to try the sensors yet, but expect everything to go well. Will update once I've had a chance to use it.

Shipping is very long two weeks, the board itself is working, packed in anti-static package

Extremely fast delivery!

C**r 07/22/2020

Collected, the scheme works, but very weak, after a few clicks stopped working. I'm not happy. Voltage gave 5 volts
