TPS7A2450DBVR

The TPS7A2450DBVR from Texas Instruments is a versatile low-dropout (LDO) linear voltage regulator designed for applications requiring low quiescent current and a wide input voltage range. It supports an input voltage from 2.4 V to 18 V and can deliver up to 200 mA of output current.

This regulator provides flexible output voltage options, including fixed outputs ranging from 1.25 V to 5.5 V and an adjustable output from 1.24 V to 17.75 V. Key electrical characteristics include a typical quiescent current of 2.0 µA, low noise of 300 µVrms, and a typical dropout voltage of 160 mV at 200 mA. It also features high power supply rejection ratio (PSRR) of 22 dB at 100 KHz and 1.25% accuracy over temperature.

Designed for ease of use, the TPS7A2450DBVR includes features such as an enable pin, active overshoot pulldown protection, thermal shutdown, and overcurrent protection. It is stable with a minimum of 1-µF output capacitors.

The device is housed in a compact 5-pin SOT-23 package, measuring 2.9 mm x 2.8 mm, making it suitable for space-constrained designs. The operating junction temperature range is -40°C to +125°C.
