The TPS7A44 low-dropout (LDO) linear voltage regulator introduces a combination of a 4-V to 65-V input voltage range with very-low quiescent current.

This device can support a wide range of input voltages (for example, a 15-s battery and 24-V to 48-V line power) and withstand line transient voltages up to 85 V. 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 1.24 V to 14.5 V at 1% accuracy. The device also provides a second intermediate output (MID_OUT) that can be set to 10 V, 12 V, and 15 V using the MVSEL pins and can be used to bias gate drivers in place of a discrete regulator.

The 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 status of the output voltage. The EN input and PG output can be used for sequencing multiple power sources in the system.
