AP7369Q-25W5-7

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AP7369Q-25W5-7 is a wide input-voltage range low-dropout linear regulator manufactured by Diodes Incorporated. It provides a fixed output voltage of 2.5V with a maximum load current capability of 150mA. The device operates within an input voltage range of 3V to 45V and features a typical quiescent current of 2.1µA. It offers high power supply rejection ratio of 85dB at 1kHz and maintains excellent line and load regulation. The component is housed in a SOT25-5 surface-mount package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix matches the required package type, as the AP7369Q series is available in both SOT25 and SOT223 configurations. Confirm that the fixed output voltage variant aligns with system requirements, as the part number indicates a 2.5V version. Ensure compliance with RoHS directives and confirm manufacturing facility certifications if automotive PPAP capabilities are required for the specific project.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this regulator when a wide input voltage range up to 45V is necessary alongside low quiescent current consumption. The device is suitable for applications requiring fast transient response and integrated protection mechanisms. Consider the SOT25 package for space-constrained designs while ensuring adequate PCB copper area is allocated for thermal dissipation due to the exposed pad requirement.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The AP7369Q belongs to Diodes Incorporated's ULDO regulator family designed for high-voltage automotive environments. Unlike standard LDOs, this series accommodates inputs up to 45V, making it ideal for direct connection to vehicle batteries or alternator lines. The Q-series designation indicates qualification for automotive quality standards, distinguishing it from general-purpose industrial variants.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include other AP7369Q variants with different output voltages such as AP7369Q-33W5-7 (3.3V) or AP7369Q-50W5-7 (5.0V). For pin-compatible alternatives with similar electrical characteristics, consider the AP7380 series, though input voltage ranges may differ.
