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
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)
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.
