The TPS717xx family of low-dropout (LDO), low-power linear regulators offers very high power supply rejection (PSRR) while maintaining very low 50A ground current in an ultra-small, five-pin SC70 package. The family uses an advanced BiCMOS process and a PMOSFET pass device to achieve fast start-up, very low noise, excellent transient response, and excellent performance. The TPS717xx is stable with a 1.0F ceramic output capacitor, and uses a precision voltage reference and feedback loop to achieve a worst-case overall accuracy of 3% over all load, line, process, and temperature variations. It is fully specified from TJ = 40C to +125C and is offered in a small, five-pin SC70 package, which is ideal for small form factor portable equipment such as wireless handsets and PDAs. |
