The TPS7B4255 is a low-dropout (LDO) voltage-tracking regulator, with high tracking accuracy and excellent load and line transient response. The device is available in a 5-pin, SOT-23 (DBV) package. The TPS7B4255 is designed to supply off-board sensors in industrial applications such as condition monitoring sensor systems. The device provides integrated protection features such as reverse polarity, output short to supply and ground, current limit, and thermal shutdown to protect against the high risk of cable failures in an off-board power system. The device is designed to survive a 45-V (absolute maximum) input voltage during extreme transient events.

A reference voltage applied at the ADJ/EN pin is effectively tracked with high accuracy for loads up to 70 mA. The high tracking accuracy provides accurate power supply to off-board modules and enables better accuracy when making measurements using ratiometric sensors.

By setting the ADJ/EN input pin low, the TPS7B4255 switches to standby mode and reduces the quiescent current to the minimum value.
