Dual-Output Low-Dropout Voltage Regulators  
with Power-Up Sequencing for Split-Voltage DSP Systems  
FEATURES  
DESCRIPTION  
•
•
•
Dual Output Voltages for Split-Supply  
Applications  
TPS701xx family devices are designed to provide a  
complete power management solution for the  
TMS320™ DSP family, processor power, ASIC,  
FPGA, and digital applications where dual output  
voltage regulators are required. Easy programmability  
of the sequencing function makes the TPS701xx  
family ideal for any TMS320 DSP applications with  
power sequencing requirements. Differentiated fea-  
tures, such as accuracy, fast transient response, SVS  
supervisory circuit, manual reset inputs, and an  
enable function, provide a complete system solution.  
Selectable Power-Up Sequencing for DSP  
Applications  
Output Current Range of 500mA on Regulator  
1 and 250mA on Regulator 2  
•
•
Fast Transient Response  
Voltage Options: 3.3V/2.5V, 3.3V/1.8V,  
3.3V/1.5V, 3.3V/1.2V, and Dual Adjustable  
Outputs  
The TPS701xx family of voltage regulators offers very  
low dropout voltage and dual outputs with power-up  
sequence control, which is designed primarily for  
DSP applications. These devices have extremely low  
noise output performance without using any added  
filter bypass capacitors and are designed to have a  
fast transient response and be stable with 10µF low  
ESR capacitors.  
•

•
•
•
Open Drain Power-On Reset with 120ms Delay  
Open Drain Power Good for Regulator 1  
Ultra Low 190µA (typ) Quiescent Current  
1µA Input Current During Standby  
Low Noise: 65µVRMS Without Bypass  
Capacitor

•
Quick Output Capacitor Discharge Feature  
Two Manual Reset Inputs  
These devices have fixed 3.3V/2.5V, 3.3V/1.8V,  
3.3V/1.5V, 3.3V/1.2V, and adjustable/adjustable volt-  
age options. Regulator 1 can support up to 500mA,  
and regulator 2 can support up to 250mA. Separate  
voltage inputs allow the designer to configure the  
source power.  
2% Accuracy Over Load and Temperature  
Undervoltage Lockout (UVLO) Feature
