DESCRIPTION
The TS3310 is a low power boost switching regulator with an industry leading low quiescent current of 150nA. The 150nA is the actual current consumed from the battery while the output is in regulation. The TS3310’s extremely low power internal circuitry consumes 90nA on average, with periodic switching cycles which service the load occurring at intervals of up to 25 seconds, together yielding the average 150nA. The TS3310 steps up input voltages from 0.9V to 3.6V to eight selectable output voltages ranging from 1.8V to 5V.
