The TPS7A43-Q1 is a wide input, low-dropout (LDO) linear voltage regulator with 4V to 85V input voltage range and very-low quiescent current. This device can support a wide range of input voltages and withstand line transient voltages up to 90V (200ms), making the device designed for direct connection to 48V, 24V, or 12V automotive battery. Ultra-low IQ of 5.5µA typical, 9µA maximum helps meet stringent system requirements and extends battery life in battery-connected applications.

The TPS7A43-Q1 output (OUT) is available in both fixed and adjustable output versions, with regulation from 1.24V to 14.5V and ±0.8% accuracy across temperature. The device is intended for use in an array of automotive applications, including supply for always-on loads like microcontrollers and wake-up functionality for various ICs (for example, CAN). The device is an efficient option to provide power to critical components during system sleep conditions. The TPS7A43-Q1 also features a second intermediate output (MID_OUT) that can be set to 10V, 12V, or 15V using the MVSEL pins. MID_OUT can supply power for LIN or be used to bias amplifiers, minimizing system complexity by eliminating the need for additional regulators.

The TPS7A43-Q1 features a precision enable input that enables or disables 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.
