The Texas Instruments TPS73201MDBVREP is a low-dropout (LDO) voltage regulator that uses a new topology with an NMOS pass element in a voltage-follower configuration. This topology provides high stability with low-ESR output capacitors, and even allows operation without a capacitor. It also provides high reverse blockage (low reverse current) and ground pin current that is nearly constant over all values of output current.

The TPS73201MDBVREP is manufactured using an advanced BiCMOS process to yield high precision while delivering low dropout voltages and low ground pin current. It can deliver up to 250mA of output current, and has a wide input voltage range of 2.5V to 5.5V. The output voltage is adjustable from 1.2V to 5.5V, using a single external resistor.

The TPS73201MDBVREP is available in a small SOT-23-5 package, making it ideal for space-constrained applications. It is also fully RoHS compliant and AEC-Q100 qualified for automotive use.
