open-in-new Find other Linear regulators (LDO)


The TPS7A26 low-dropout (LDO) linear voltage regulator supports a 2.4-V to 18-V input voltage range with very-low quiescent current (IQ). These features help modern appliances meet increasingly stringent energy requirements and help extend battery life in portable-power solutions.

The TPS7A26 is available in both fixed and adjustable versions. For more flexibility or higher output voltages, the adjustable version uses feedback resistors to set the output voltage from 1.24 V to 17.4 V. Both versions have 1% output regulation accuracy that provides precision regulation for microcontroller (MCU) references.

With the open-drain, power-good (PG) output the device can provide a reset to an MCU or be wire-ORed and level-shifted with other open-drain PGs to provide a system-wide PG or reset.

The TPS7A26 LDO operates more efficiently than standard linear regulators because the maximum dropout voltage is less than 590 mV at 500 mA of current. This maximum dropout voltage allows for 87.7% efficiency from a 5.7-V input voltage (VIN) to
5.0-V output voltage (VOUT).

For lower power applications, consider the TPS7A25.
