Texas Instruments TPS7A80 Low-Dropout Linear Regulators (LDOs)
Texas Instruments TPS7A80 Low-Dropout Linear Regulators (LDOs) offer very high power-supply ripple rejection (PSRR) at the output. These LDO regulators use an advanced BiCMOS process and a PMOSFET pass device to achieve very low noise, excellent transient response, and excellent PSRR performance. The TPS7A80 family is stable with a 4.7µF ceramic output capacitor and uses a precision voltage reference and feedback loop to achieve a worst-case accuracy of 3% overall load, line, process, and temperature variations. These devices are fully specified over the temperature range of –40°C to +125°C. The Texas Instruments TPS7A80 is offered in a 3mm×3mm, VSON-8 package with a thermal pad.Features
