3 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 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).
