Part Description

The TPS717 family of low-dropout (LDO), low-power linear regulators offers very high power-supply rejection (PSRR) while maintaining very low 45-μA ground current in an ultra-small, five-pin SOT package. The family uses an advanced BiCMOS process and a PMOS pass device to achieve fast start-up, very low noise, excellent transient response, and excellent PSRR performance. The TPS717 is stable with a 1-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. The device family is fully specified from TJ = –40°C to 125°C and is offered in a small SOT (SC70-5) package, a 2-mm × 2-mm WSON-6 package with a thermal pad, and a 1.5-mm × 1.5-mm WSON-6 package, which are ideal for small form factor portable equipment (such as wireless handsets and PDAs).
