High efficiency 3.3V regulator
The LTC1174-3.3 current mode DC/DC converter provides efficiencies better than 90% over a wide load current range while requiring only 1μA in shutdown.
3.3V battery-powered supply with shutdown
The LT1121-3.3 low dropout linear regulator provides up to 150mA output current with 30μA quiescent current.
3.3V supply with shutdown
The LT1129-3.3 low dropout ...
