TPS78228 单路固定输出 LDO、150mA、0.5µA 静态电流
TPS78228 描述
The TPS782 family of low-dropout regulators (LDOs) offers the benefits of ultra-low power (IQ = 1µA), and miniaturized packaging (2×2 SON).
This LDO is designed specifically for battery-powered applications where ultra-low quiescent current is a critical parameter. The TPS782, with ultra-low IQ (1µA), is ideal for microprocessors, memory cards, and smoke detectors.
The ultra-low power and miniaturized packaging allow designers to customize power consumption for specific applications. Consult with your local factory representative for exact voltage options and ordering information; minimum order quantities may apply.
The TPS782 family is designed to be compatible with the TI MSP430 and other similar products
