TPS717-Q1

SLVSBM4C –SEPTEMBER 2012–REVISED JANUARY 2016

TPS717-Q1

Low-Noise, High-Bandwidth PSRR, Low-Dropout, 150-mA Linear Regulator

1 Features

3 Description

The TPS717-Q1 family of low-dropout (LDO), low-

power linear regulators offers very high power-supply

rejection (PSRR) and maintains very low 45-μA

ground current in an ultra-small, five-pin SOT

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 PSRR performance. The TPS717-Q1 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 T_J, T_A= –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). The TPS717-

Q1 family of LDOs is qualified for AEC-Q100 grade 1.
