SBVS393B December 2020 – November 2022 TPS7A43
PRODUCTION DATA
The TPS7A43 low-dropout (LDO) linear voltage regulator introduces a combination of a 4-V to 85-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 TPS7A43 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 TPS7A43 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.
