- TIDA-00599, LP5910 and TPS61221 as Power Reference Design for devices Interacting with Ultra-Low Voltage MSP430. The MSP430X09X can operate form ultra-low voltages (ULV) in the range of 0.9V to 1.65V, however most of the devices in the system requires higher voltages. TIDA-00599 provides a solution for those companion devices that requires 1.8V and 3.3V input voltages. A 3.3V voltage rail is generated from a 0.9V to 1.65 V batteries using the TPS61221 boost converter and a 1.8V voltage rail is generated using a high PSRR LDO (LP5910) connected in series with the boost converter output voltage rail. The combine output current is 100 mA at 1.65V input voltage and 50 mA at 0.90 V input voltage
