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

FEATURES
DESCRIPTION
The TPS717xx family of low-dropout (LDO),
low-power linear regulators offers very high power
supply rejection (PSRR) while maintaining very low
50µA 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 PSRR performance. The TPS717xx is
stable with a 1.0µF 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. It is fully
specified from T
J
= –40°C to +125°C and is offered in
a small SC70-5 package, a 2mm
×
2mm SON-6
package with a thermal pad, and a 1.5mm
×
1.5mm
SON package, which are ideal for small form factor
portable equipment such as wireless handsets and
PDAs.
