AP7362-33SP-13

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

The AP7362-33SP-13 is a fixed-output linear regulator from Diodes Incorporated, delivering a nominal 3.3V at up to 1.5A. It operates within an input voltage range of 2.2V to 5.5V and features ultra-low dropout characteristics, specified at 190mV under full load. The device incorporates internal current limit and thermal shutdown protection. It utilizes an SO-8EP package and includes an enable pin for logic-controlled power management.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Ultra-low dropout performance ensures stable regulation with minimal voltage difference between input and output.
• Integrated enable function allows precise control via high or low logic signals.
• Built-in thermal shutdown and current limit mechanisms protect the IC during fault conditions.

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

• ASIC power supplies in printers, graphics cards, and set-top boxes
• FPGA and DSP core or I/O power supplies
• Step-down conversion from 3.3V or 5V rails

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

Verify that the specific suffix SP corresponds to the SO-8EP package configuration required for the target PCB footprint. Confirm that the -13 packaging suffix aligns with the intended reel quantity for automated assembly processes. Ensure the fixed 3.3V output variant matches the system voltage requirements without needing external adjustment resistors.

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

Select this component when a fixed 3.3V rail is required with high current capability up to 1.5A. The SO-8EP package offers improved thermal dissipation compared to smaller footprints. Consider the wide input voltage range suitable for systems powered by single-cell lithium batteries or standard 5V lines.

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

This part belongs to the AP7362 family of low quiescent current, fast transient ultra-low dropout linear regulators. The series provides both adjustable and fixed output options, designed for low-to-medium power applications requiring efficient voltage regulation and robust protection features.

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

Compatible substitutes include other 1.5A LDOs with similar SO-8EP packages and 3.3V fixed outputs. Verify that alternative parts match the 190mV dropout specification and support the same 2.2V to 5.5V input range to ensure circuit compatibility.
