TPS7A8001 描述
The TPS7A80xx family of low-dropout linear regulators (LDOs) offer very high power-supply ripple rejection (PSRR) at the output. This series of LDOs uses an advanced BiCMOS process and a PMOSFET pass device to achieve very low noise, excellent transient response, and excellent PSRR performance.
The TPS7A80xx 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% over all load, line, process, and temperature variations.
This device is fully specified over the temperature range of TJ = –40°C to +125°C and is offered in a 3mm × 3mm, SON-8 package with a thermal pad.
