Texas Instruments TPS7A44 Low-Dropout (LDO) Linear Voltage Regulators introduce a combination of a 4V to 65V input voltage range with a 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 meet increasingly stringent energy requirements and help extend battery life in portable power solutions.
The TPS7A44 output (OUT) is available in both fixed and adjustable output versions, which can regulate from 1.24V to 14.5V at 1% accuracy. The device also provides a second intermediate output (MID_OUT) that can be set to 10V, 12V, and 15V using the MVSEL pins and can be used to bias gate drivers in place of a discrete regulator.
The Texas Instruments TPS7A44 features a precision enable input that helps enable or disable the LDO at a fixed and accurate threshold voltage using a resistor divider from the input. The Power-Good (PG) output is used to monitor the voltage at the feedback pin to indicate the output voltage status. The EN input and PG output can be used for sequencing multiple power sources in the system.
