Integrated MCU Power Solution for C2000™ Microcontrollers  
Check for Samples: TPS75005

FEATURES  
DESCRIPTION  
The TPS75005 is a complete power management  
solution for Texas Instruments' C2000 real-time  
microcontrollers and other DSP, FPGA, and ASIC  
MCUs. The device has been tested with and meets  
TI's F2833x (DELFINO), F2823x, F281x, and  
F280x/F2801x power requirements.

•
Optimized to Supply TI's C2000 MCU Series:  
F2833x ( DELFINO™), F2823x, F281x, and  
F280x/F2801x  
•
Dual 500-mA Voltage Regulators with  
Dedicated Supply Voltage Supervisors (SVSs)  
•
•
One Auxiliary SVS  
All of these C2000 controllers require ±5% power-rail  
accuracy. With the combination of high-accuracy,  
low-dropout regulators (LDOs) and dedicated SVSs,  
the device allows for a ±5% power supply to the  
C2000 with a power-good (PG) signal. (For more  
details, see Application Report SBVA032, LDO+SVS  
Combined Accuracy.)  
LDO1 and SVS1 for 1.8 V/1.9 V (Selectable):  
±5% Specified with PG  
•
LDO2 and SVS2 for 3.3 V:  
±5% Specified with PG  
•
•
•
Input Voltage Range: 3.75 V to 6.5 V  
Independent Soft-Start for LDO1 and LDO2  
Two power outputs are controlled by an integrated  
sequencer circuit. A single EN logic input signal  
makes sure that the power-up and power-down  
requirements of the C2000 controllers are met. The  
sequencer includes a soft-start for both LDOs to  
avoid inrush current. A third rail monitor is provided  
for general-purpose monitoring (for example, to  
monitor input voltage).
