The TS2940CW-3.3 is part of a family of low dropout (LDO) regulators by Taiwan Semiconductor. It is a voltage regulator specifically designed to provide a regulated 3.3V output at up to 2A current. The device features an extremely low dropout voltage, low quiescent current, excellent line and load regulation, and an ultra-high PSRR (power supply rejection ratio). It also features an external enable pin, allowing it to be turned off completely when not in use, saving power and extending battery life. The TS2940CW-3.3 is ideal for a wide range of applications such as cellular phones, battery- operated products, portable equipment, and any other device where a low dropout, high efficiency, low noise, and low quiescent current are desired.
