Product Introduction
The TPS781 family of low-dropout (LDO) regulators offer the benefits of ultralow power (IQ = 1µA), miniaturized packaging (2×2 SON-6), and selectable dual-level output voltage levels. An adjustable version is also available, but does not have the capability to shift 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 lQ(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 EPROM technique allows for numerous output voltage options between VSET low (1.5V to 4.2V) and VSET high (2.0V to 3.0V) in the fixed output version only.
The TPS781 series are designed to be compatible with the TI MSP430 and other similar products. The enable pin is compatible with standard CMOS logic. This LDO is stable with any output capacitor greater than 1.0µF. Therefore, implementations of this device require minimal board space because of miniaturized packaging and a potentially small output capacitor. The TPS781 series IQ (1µA) also come with thermal shutdown and current limit to protect the device during fault conditions. All packages have an operating temperature range of TJ = -40°C to +125°C.
