Technical Data  
Dual Output DC-DC & Linear  
Regulator IC  
The 34710 is a dual-output power regulator IC integrating  
switching regulator, linear regulator, supervisory and power supply  
sequencing circuitry. With a wide operating input voltage range of  
13 V to 32 V, the 34710 is applicable to many commercial and  
industrial applications using embedded MCUs.

DUAL OUTPUT DC-DC & LINEAR  
REGULATOR  
A mode-selected 5.0 Vor 3.3 V DC-DC switching regulator is  
provided for board-level I/O and user circuitry up to 700 mA. A linear  
regulator provides mode-selected core supply voltages of either 3.3V,  
2.5V,1.8V, or 1.5V at currents up to 500 mA.  
The supervisor circuitry ensures that the regulator outputs follow a  
predetermined power-up and power-down sequence.
