Texas Instruments TLV740 Low-Dropout (LDO) Linear Regulator
Texas Instruments TLV740 Low-Dropout (LDO) Linear Regulator is a low-quiescent current LDO with excellent line and load transient performance designed for power-sensitive applications. This device typically achieves an accuracy of 1%. The TLV740 also provides inrush current control during device power-up and enabling. The Texas Instruments TLV740 limits input current to the specified limit to prevent excessive current from flowing from the input power source. This functionality is especially important in battery-operated devices. The TLV740 also provides an active pulldown circuit to quickly discharge output loads.
