(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum
conditions for extended periods may degrade device reliability. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those specified is not
implied.
(2) VEN absolute maximum rating is VIN + 0.3V or +7.0V, whichever is greater.


Description

The TPS717xx family of low-dropout (LDO), low-power linear regulators offers very high power supply rejection (PSRR) while maintaining very low 50mA ground current in an ultra-small, five-pin SC70 package. The TPS717xx 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 1.0mF 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. TPS717xx is fully specified from T_J = 40°C to +125°C 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.
