Description

General part information

TPS7A44 Series

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.
