Product Overview
TPS7A05 is a Texas Instruments low-dropout linear regulator in the Power_Management category. The device is specified for a recommended input voltage range of 1.4 V to 5.5 V and fixed nominal output-voltage versions from 0.8 V to 3.3 V. Its recommended output-current range is 0 mA to 200 mA, with output current limit specified from 210 mA minimum to 700 mA maximum under the stated test condition.
Package options include X2SON-4 1.00 mm x 1.00 mm, DSBGA-4 0.65 mm x 0.65 mm, SOT-23-5 2.90 mm x 1.60 mm, and SOT-23-3 2.90 mm x 1.60 mm. The recommended external capacitor conditions are 1 µF at the input and an output capacitor from 0.47 µF minimum to 22 µF maximum, with 1 µF nominal.
The device includes enable control with a recommended enable voltage range from 0 V to VIN. It is specified across an operating junction temperature range of -40°C to +125°C, with shutdown current, ground current, dropout voltage, line regulation, load regulation, PSRR, and ESD ratings defined in the manufacturer technical datasheet.
