Product Overview
The TPS7A7001 is a Texas Instruments positive-voltage low-dropout linear regulator for Power_Management designs. It supports a maximum recommended output current of 2 A and operates from a recommended input voltage range of 1.425 V to 6.5 V. The output can be programmed as low as 0.5 V, with reference voltage specified at 0.490 V minimum, 0.500 V typical, and 0.510 V maximum under the stated feedback test condition.
Dropout performance is specified as 200 mV typical at 1.0 A, 300 mV typical at 1.5 A, and 380 mV typical at 2.0 A across 0.5 V to 5.0 V output settings. Output accuracy is specified at +/-2% or +/-3% depending on operating condition, with line regulation of 0.2 %/V typical and 0.4 %/V maximum, and load regulation of 0.25 %/A typical and 0.75 %/A maximum.
The device is supplied in an 8-pin SO PowerPAD (DDA) package with a 3.90 mm x 4.89 mm nominal body size. Stability requires an OUT-pin capacitor of 4.7 uF or larger, with recommended input and output capacitor ranges, feedforward capacitance limits, enable input thresholds, current-limit behavior, thermal shutdown, and package thermal metrics specified in the datasheet facts.
