TPS780300250 具有引脚可选双电平输出电压的 150mA Iq 500nA 超低功耗 LDO 稳压器
TPS780300250 描述
The TPS780 family of low-dropout (LDO) regulators offer the benefits of ultralow power (IQ = 500nA), 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 IQ (500nA), 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.
