150mA,低压降稳压器,超低功耗,智商1毫安与引脚可选,双电平输出电压 150mA, Low-Dropout Regulator, Ultralow-Power, IQ 1mA with Pin-Selectable, Dual-Level Output Voltage
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 levelsThe TPS781 series are designed to be compatible with the 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. For high-performance applications requiring a dual-level voltage option, consider the TPS780 series, with an IQ of 500nA and dynamic voltage scaling.
