6.1 Overview

The TPS7A7100 is a low-dropout (LDO) regulator that uses innovative circuitry to offer very low dropout voltage along with the flexibility of a programmable output voltage.

The dropout voltage for this LDO regulator is 0.14 V at 1 A. This voltage is makes the TPS7A7100 into a point-of-load (POL) regulator because 0.14 V at 1 A is lower than any voltage gap among the most common voltage rails: 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3 V, and 3.3 V. This device offers a fully user-configurable output voltage setting method. The TPS7A7100 output voltage can be programmed to any target value from 0.9 V to 3.5 V in 50-mV steps.

Another big advantage of using the TPS7A7100 is the wide range of available operating input voltages: from 1.5 V to 6.5 V. The TPS7A7100 also has very good line and load transient response. All these features allow the TPS7A7100 to meet most voltage-regulator needs for under 6-V applications, using only one device so less time is spent on inventory control.

Texas Instruments also offers different output current ratings with other family devices: the TPS7A7200 (2 A) and TPS7A7300 (3 A).
