Low Noise, High-Bandwidth PSRR
Low-Dropout 150mA Linear Regulator
23
• 150mA Low-Dropout Regulator with Enable
The TPS717xx family of low-dropout (LDO),
low-power linear regulators offers very high power
• Low I
Q
: 45 µ A (typical)
supply rejection (PSRR) while maintaining very low
• Available in Multiple Output Versions:
45 µ A ground current in an ultra-small, five-pin SC70
– Fixed Output with Voltages from 0.9V to
package. The family uses an advanced BiCMOS
5.0V Using Innovative Factory EEPROM
process and a PMOSFET pass device to achieve fast
Programming
start-up, very low noise, excellent transient response,
and excellent PSRR performance. The TPS717xx is
– Adjustable Output Voltage from 0.9V to
stable with a 1.0 µ F ceramic output capacitor, and
6.2V
uses a precision voltage reference and feedback loop
• Ultra-High PSRR:
to achieve a worst-case accuracy of 3% over all load,
– 70dB at 1kHz, 67dB at 100kHz and 45dB at
line, process, and temperature variations. It is fully
1MHz
specified from T
J
= – 40 ° C to +125 ° C and is offered in
a small SC70-5 package, a 2mm × 2mm SON-6
• Low Noise: 30 µ V typical (100Hz to 100kHz)
package with a thermal pad, and a 1.5mm × 1.5mm
• Stable with a 1.0 µ F Ceramic Capacitor
SON package, which are ideal for small form factor
• Excellent Load/Line Transient Response
portable equipment such as wireless handsets and
PDAs.
• 3% Overall Accuracy (over Load/Line/Temp)
• Over-Current and Over-Temperature
Protection
• Very Low Dropout: 170mV Typical at 150mA
• Small SC70-5, 2mm x 2mm SON-6, and 1.5mm
× 1.5mm SON-6 Packages
• Mobile Phone Handsets
• Wireless LAN, Bluetooth
