LTC1474/LTC1475, high efficiency switching regulators that draw only 10μA supply current, are described.
Maximizing battery life, one of the key design requirements for all battery-powered products, is now easier with Linear Technology’s new family of ultralow quiescent current, high efficiency step-down regulator ICs, the LTC1474 and LTC1475. The LTC1474 and LTC1475 are step-down regulators with on-chip P-channel MOSFET power switches. These regulators draw only 10μA supply current at no load while maintaining the output voltage. With the on-chip switch (1.4Ω at VIN = 10V), minimal external ...
