TPS7A8101DRBR

TPS7A8101DRBR is the tape-and-reel VSON-8 (DRB) ordering code for the Texas Instruments TPS7A8101 adjustable low-dropout regulator, listed by TI as Active in the Package Option Addendum dated 31 October 2025. Its internal reference sits between 0.79 V and 0.81 V (0.80 V typical), the dropout is 170 mV typical at a 1 A load in the datasheet features with an electrical-characteristics maximum of 500 mV at the same load - two figures with different standing that must not be merged - the current limit runs between 1100 mA and 2000 mA (1400 mA typical), and output noise is 23.5 µVRMS typical. The selection point is low-noise adjustable regulation at ampere class: RF, data-converter and clocking rails that need a settable voltage with dropout headroom a fixed regulator cannot trim. Selection advice: design dropout margin against the 500 mV electrical maximum at full load, treating the 170 mV typical as a characterisation figure only; and set the output with the feedback divider values the datasheet specifies for the 0.8 V reference. Parameters verified against the TI TPS7A8101 datasheet and the current Package Option Addendum.
