Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community TPS7A8101 SBVS179B – DECEMBER 2011 – REVISED AUGUST 2015 TPS7A8101 Low-Noise, Wide-Bandwidth, High PSRR, Low-Dropout 1-A Linear.

General Description

The TPS7A8101 low-dropout linear regulator (LDO) offers very good performance in noise and powersupply rejection ratio (PSRR) at the output.

This LDO uses an advanced BiCMOS process and a PMOSFET pass device to achieve very low noise, excellent transient response, and excellent PSRR performance.

The TPS7A8101 device is stable with a 4.7-μF ceramic output capacitor, and uses a precision voltage reference and feedback loop to achieve a worst-case accuracy of 3% over all load, line, process, and temperature variations.
