TPS7A24 Low Dropout (LDO) Linear Voltage Regulator with Power Good

Texas Instruments' 300 mA regulator is available in a fixed-output voltage version and an adjustable-output voltage version

Image of Texas Instruments' TPS7A24 LDO Linear Voltage RegulatorTexas Instruments' TPS7A24 LDO linear voltage regulator supports a 2.4 V to 18 V input voltage range with ultra-low quiescent current (IQ). These features help modern appliances meet increasingly stringent energy requirements and help extend battery life in portable power solutions.

The TPS7A24 is available in fixed and adjustable versions. The fixed-voltage version eliminates external resistors and minimizes the needed printed circuit board (PCB) area. For more flexibility or higher output voltages, the adjustable version uses feedback resistors to set the output voltage from 1.24 V to 17.75 V. Both versions offer 2% output regulation accuracy that provides precision regulation for microcontroller (MCU) references.

The TPS7A24 LDO operates more efficiently than standard linear regulators because the maximum dropout voltage is less than 250 mV at 200 mA of current. This maximum dropout voltage allows for 92.8% efficiency from a 3.55 V input voltage (VIN) to a 3.3 V output voltage (VOUT).
