The Texas Instruments TPS7A1901DRBR is a versatile low-dropout linear regulator (LDO) designed for a wide range of applications. It supports an input voltage range from 4V to 40V and can deliver an output current of up to 450mA. The output voltage is adjustable, ranging from 1.5V to 18V, providing flexibility for various design needs.
Key electrical characteristics include a low quiescent current of 15µA and a dropout voltage of 450mV at 400mA. The regulator also features an Enable pin for control and protection mechanisms such as overcurrent and overtemperature shutdown. Its PSRR is rated at 45dB at 100KHz.
This device is housed in an 8-SON (3x3) package, suitable for surface mount applications. The operating temperature range is from -40°C to 125°C, making it suitable for demanding environments. The TPS7A1901DRBR is designed for stability with ceramic output capacitors.
