AP7362-18SP-13

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

The AP7362-18SP-13 is a fixed-output linear regulator from Diodes Incorporated, providing a stable 1.8V output at up to 1.5A load current. It operates within an input voltage range of 2.2V to 5.5V and features ultra-low dropout characteristics, with a typical dropout voltage of 190mV at full load. The device incorporates internal enable logic for power management, alongside overcurrent and thermal shutdown protections. It is housed in an SO-8EP surface-mount package.

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

• Fixed 1.8V output configuration with high current capability
• Ultra-low dropout performance for efficient low-voltage operation
• Integrated enable pin for active high control logic
• Built-in thermal shutdown and current limit protection

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

• FPGA and DSP core or I/O power supplies
• ASIC power supplies in printers and graphics cards
• Conversion from 3.3V or 5V rails
• SMPS regulator stages

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

Verify the specific suffix 'SP' confirms the SO-8EP package variant rather than the U-DFN2030-8 option. Confirm the '-13' packaging code matches the required tape and reel quantity of 2500 units. Ensure the fixed 1.8V designation aligns with circuit requirements, as adjustable versions use different suffixes.

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

Select this component when a precise 1.8V rail is required without external resistor dividers. The SO-8EP package offers distinct thermal dissipation characteristics compared to the DFN variant. Verify that the system input voltage remains within the 2.2V to 5.5V operational window to ensure proper regulation and stability.

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

This part belongs to the AP7362 family of 1.5A low quiescent current linear regulators. The series includes both adjustable and fixed voltage options across multiple packages. The AP7362-18SP-13 specifically denotes the fixed 1.8V version manufactured in the SO-8EP footprint, distinguishing it from the adjustable ADJ variants.

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

AP7362-18HA-7 serves as a direct functional substitute utilizing the U-DFN2030-8 package instead of the SO-8EP form factor.
