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 60¬µVrms from 10Hz to 100kHz. This regulator is characterized by low quiescent current, as low as 35¬µA, 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¬8C to +125¬8C, making it robust for various environmental conditions.
