TPS73601DBVR Introduction

The TPS73601DBVR from Texas Instruments is the best when it comes to precise voltage regulation.

With the TPS73601DBVR from Texas Instruments, you can see how powerful exact voltage regulation can be. This regulator gives your devices stable power with an accuracy of 0.5% and an output voltage that can be changed from 1.2 to 5.5 V. It has a low dropout voltage of 0.075 V at 400 mA and can handle 0.4 A of current. This makes it easy to control power. This regulator is ready to improve your projects. It comes on a tape and reel for safe shipping and easy installation. When you upgrade to the TPS73601DBVR, you can control the power more reliably than ever before.

TPS73601DBVR Feature Description

● Enable Pin and Shutdown

The TPS73601DBVR has an activate pin (EN) that works as an active high and is compatible with standard TTL-CMOS levels. When the voltage on the EN pin (VEN) drops below the maximum of 0.5 V, the regulator turns off, and the current through the GND pin drops to about 10 nA.

By using the EN bit to turn off the regulator, all the charge on the pass transistor gate is drained. This makes the output slowly rise back up to the regulated VOUT level. If you don’t need the option to shut down, you can connect the EN pin directly to the VIN pin.

But it’s important to keep in mind that in this setup, the pass gate may not properly discharge, which could leave the pass transistor in an increased state for a long time after VIN has been turned off. If the IN pin has a low resistance, this can cause current to flow in the wrong direction, and power-up times will be faster. Also, if the ramp times for VIN are longer than a few milliseconds, the output voltage may overshoot when the power is turned on. It’s important to note that the current limit on foldback can stop the gadget from turning on in some situations.

By keeping these things in mind and carefully managing the enable pin and power-up process, you can get the most out of the TPS73601DBVR and make sure it works well in your circuits.

● Reverse Current

The TPS736xx has an NMOS pass element that prevents current from passing from the regulator’s output to its input when the gate of the pass device is pulled low. Before turning off the input voltage, the EN bit must be driven low to make sure that all of the charge is removed from the pass element’s gate. If you don’t do this, the pass part might stay on because the gate is still charged.

Once the EN pin is pushed low, no bias voltage is needed on any pin to stop the flow of current in the opposite direction. It’s important to know that reverse current is described as the current flowing out of the IN pin when voltage is applied to the OUT pin. A current is also flowing into the OUT pin because there is an 80-k resistor divider inside the chip that is linked to ground.

By carefully controlling the EN bit and making sure it is in the low state before turning off the input voltage, you can stop reverse current flow and make the TPS736xx regulator work as well as possible.

Device Functional Modes

● Normal Operation with 1.7 V, VIN 5.5 V, and VEN 1.7 V

To make sure the TPS736xx family works well and stays in control, it’s important to give it an input voltage of at least 1.7 V. But it’s important to know that if the device’s output voltage is higher than 1.5 V and the input voltage is 1.7 V, the device will go into dropout mode and cannot be regulated.

The TPS736xx devices use an NMOS architecture, which means that the dropout voltage is not greatly affected by the input voltage. But when the device is being used close to its maximum voltage rating of 5.5 V, care should be taken to stop any temporary spikes that might go over the exact maximum voltage limit of 6.0 V. To avoid damage, it is important to make sure that the gadget never runs at a continuous DC voltage of more than 5.5 V.

By following these voltage requirements and taking the required precautions, you can make sure that the TPS736xx family of devices works well and lasts as long as it should.
