TPS7B6950DBVR

The Texas Instruments TPS7B6950DBVR is a low-dropout (LDO) linear voltage regulator designed for applications requiring stable power delivery from a wide input voltage range. It operates with an input voltage from 4V up to 40V, withstanding transients up to 45V. The device provides a fixed 5V output voltage and can deliver a maximum output current of 150mA.

A key feature of the TPS7B6950DBVR is its ultralow quiescent current, typically 15 µA at light loads and a maximum of 25 µA under full temperature conditions. This makes it suitable for always-on systems and battery-powered devices. The regulator offers excellent line and load regulation, with maximums of 10mV and 20mV, respectively. It also includes integrated fault protection, such as thermal shutdown and short-circuit protection.

Designed for ease of use, the TPS7B6950DBVR is stable with low-ESR ceramic output capacitors. It is available in a compact 5-pin SOT-23 package, suitable for surface-mount applications where space is limited. The operating temperature range is -40°C to 105°C.

This LDO is well-suited for applications such as e-meters, appliances, fire alarms, smoke detectors, and medical devices where low power consumption and reliable voltage regulation are critical.
