Overview
The TPS73130DBVR is a low-dropout linear voltage regulator produced by Texas Instruments. This regulator is designed using an advanced BiCMOS process, which enables high precision, very low dropout voltages, and minimal ground pin current. It is particularly suited for portable applications due to its ultra-low current consumption of less than 1 μA in shutdown mode. The device features extremely low output noise, making it ideal for powering noise-sensitive components such as voltage-controlled oscillators (VCOs).
