DIODES Incorporated Voltage Regulators - Linear, Low Drop Out (LDO) Regulators AP7343DQ-29W5-7

The AP7343DQ-29W5-7 is a low dropout linear voltage regulator designed for automotive applications, capable of delivering a guaranteed output current of 300mA. It operates within a wide input voltage range of 1.7V to 5.25V and provides a fixed output voltage of 2.9V with an accuracy of ±1%. The device features a high power supply rejection ratio (PSRR) of 75dB at 1kHz, ensuring minimal output noise, which is measured at 60µVrms from 10Hz to 100kHz. This regulator is characterized by low quiescent current, as low as 35µA, making it suitable for power-sensitive applications. It is qualified under AEC-Q100, ensuring compliance with automotive standards, and is manufactured in IATF 16949 certified facilities. The AP7343DQ-29W5-7 is available in a compact SOT25 package, facilitating dense PCB layouts. Its operational temperature range spans from -40°C to +125°C, making it robust for various environmental conditions.
