TPS71918-12DRVT is an advanced family of low-dropout regulators (LDOs) that integrates dual-channel and/or high-current/high-side PDU with enhanced protection. Regulated output and adjustable output voltage from 1.2V to 12V with up to 5A continuous current and up to 8A transient current output based on the input voltage. It is suitable for a wide range of applications such as power conversion, automotive, medical, industrial and consumer. 

The TPS71918-12DRVT is versatile, low-cost, easy-to-use and reliable when compared with other monitoring solutions. The part offers a wide operating temperature range from -40°C to +125°C that enables system designers to use the TPS71918-12DRVT in a variety of challenging environments. Furthermore, it provides a variety of features including exact voltage tracking, phase control or 45mV under voltage lock-out threshold (UVLO), buffered VIN, soft-start, compensation, and external shutdown.

The TPS71918-12DRVT is typically used for power supplification for other devices and offers low-dropout characteristics, low quiescent current, high power conversion efficiency, and low draw overload current protection. The LDO designed with tight voltage regulation, low-ESD protection, and startup current limitation. It also provides thermal shutdown and ESD protection.

The working principle of this device is quite simple. The input voltage is received through an integrated voltage regulator and then filtered through a low-pass filter. The voltage is then converted using an amplifier and an output voltage regulator. The output voltage is then input to the regulator’s compensation circuit. The compensation circuit adjusts the input voltage to the output voltage to maintain the desired voltage level. If a voltage peak or trough is detected, the device reacts and changes its output voltage accordingly.
