TPS78101DDCR

The TPS78101DDCR is a low-dropout (LDO) Regulator offers the benefits of ultralow power and selectable dual-level output voltage levels. The VSET pin allows the end user to switch between two voltage levels on-the-fly through a microprocessor-compatible input. This LDO is designed specifically for battery-powered applications where dual-level voltages are needed. With ultralow IQ (1µA), microprocessors, memory cards and smoke detectors are ideal applications for this device. The ultralow-power and selectable dual-level output voltages allow designers to customize power consumption for specific applications. Designers can now shift to a lower voltage level in a battery-powered design when the microprocessor is in sleep mode, further reducing overall system power consumption. The two voltage levels are preset at the factory through a unique architecture using an EPROM. The enable pin is compatible with standard CMOS logic. This LDO is stable with any output capacitor greater than 1µF.
