Introduction

AI Translation

The TPS7A24 low-dropout (LDO) linear regulator supports an input voltage range of 2.4V to 18V and features an ultralow quiescent current (IQ). These characteristics help modern appliances meet increasingly stringent energy requirements and extend battery life in portable power solutions.

The TPS7A24 is available in both fixed-voltage and adjustable-voltage versions. The fixed-voltage version requires no external resistors, minimizing PCB footprint. For greater flexibility or higher output voltages, the adjustable-voltage version uses feedback resistors to set the output voltage between 1.24V and 17.75V. Both versions offer 1.25% output regulation accuracy, enabling precise regulation of MCU reference voltages.

At 200mA, the TPS7A24 LDO features a maximum dropout voltage of less than 250mV, making it more efficient than standard linear regulators. This maximum dropout voltage achieves an efficiency of 92.8% across an input voltage (VIN) of 3.55V to an output voltage (VOUT) of 3.3V.
