FEATURES  
DESCRIPTION  
23  
•
Dual Output Voltages for Split-Supply  
TPS707xx 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 TPS707xx  
family ideal for any TMS320 DSP applications with  
power sequencing requirements. Differentiated  
features, such as accuracy, fast transient response,  
SVS supervisory circuit, manual reset inputs, and an  
enable function, provide a complete system solution.  
Applications  
•
•
Selectable Power-Up Sequencing for DSP  
Applications (See Part Number TPS708xx for  
Independent Enable Outputs)  
Output Current Range of 250mA on Regulator  
1 and 125mA 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 TPS707xx family of voltage regulators offer 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  
Ultralow 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  
voltage options. Regulator 1 can support up to  
250mA, and regulator 2 can support up to 125mA.  
Separate voltage inputs allow the designer to  
configure the source power.  
2% Accuracy Over Load and Temperature
