The TLV74118PDBVR is an ultra-low-dropout voltage regulator with 150mA load current range manufactured by Texas Instruments. It is a three-terminal integrated circuit with an output voltage accuracy of ±0.4%, a dropout voltage of 250mV at 150mA, an input voltage range of 1.8V to 10V, and a temperature range of -40°C to +125°C. The maximum input/output differential voltage is 40V. It is thermal and short-circuit protected and provides an output voltage of +3.3V, +5V, or +9V. It is ideal for applications demanding high power efficiency and low dropout voltage, such as point-of-load systems, portable electronic equipment, cellular phones, and battery-overload protection. It also features low quiescent current, high power supply rejection ratio (PSRR), fast transient response, output current limiter, and noise reduction circuitry.
