TPS7A43/-Q1 LDO Linear Voltage Regulators

Texas Instruments TPS7A43/-Q1 Low-Dropout (LDO) Linear Voltage Regulators offer a 4V to 85V input voltage range and very low quiescent current. This device can support a wide range of input voltages (for example, a 15s battery and 24V to 48V line power) and withstand line transient voltages up to 85V. These features help modern applications extend battery life and meet increasingly stringent energy requirements in portable power solutions.
