AP7368D-12RS4-7

Special Purpose Regulators Overview

The AP7368D-12RS4-7 is a single-output low dropout (LDO) voltage regulator manufactured by Diodes Incorporated. It provides a fixed 1.2 V output with a maximum load current of 1 A. The device operates within an input voltage range of 1.7 V to 5.5 V and features a typical power supply rejection ratio (PSRR) of 80 dB. Quiescent current is specified at 110 uA, while the maximum dropout voltage is 240 mV. Line regulation is 0.02 %/V and load regulation is 1 mV. Power dissipation reaches 1.7 W. It functions in temperatures from -40°C to +85°C and is housed in an X1-DFN1612-8 surface-mount package.

Special Purpose Regulators Feature Summary

• Delivers high output current capability of 1 A for demanding load applications
• Provides excellent noise filtering with a typical PSRR of 80 dB
• Maintains tight output accuracy through low line and load regulation specifications
• Operates efficiently with minimal quiescent current consumption

Special Purpose Regulators Applications

• Portable electronic devices requiring stable low-voltage power rails
• Embedded systems utilizing microcontrollers or digital logic
• Battery-powered equipment needing efficient linear regulation
• Noise-sensitive analog circuits requiring clean power supplies

Special Purpose Regulators Procurement Notes

Verify the complete part number including suffixes against official Diodes Incorporated documentation to ensure correct output voltage and packaging configuration. Confirm RoHS compliance status via the manufacturer's datasheet. Cross-reference the X1-DFN1612-8 footprint dimensions during PCB layout to prevent assembly errors. Ensure thermal management strategies align with the 1.7 W power dissipation rating under expected operating conditions.

Special Purpose Regulators Selection Notes

Select this component when a fixed 1.2 V rail is required with up to 1 A continuous current. The wide input voltage range supports various battery chemistries and system voltages. The compact X1-DFN1612-8 package suits space-constrained designs. Evaluate thermal performance carefully as high current combined with dropout voltage generates significant heat, potentially requiring copper area optimization on the PCB for adequate heat sinking.

Special Purpose Regulators Part Context

This LDO belongs to the AP7368 series of standard low-dropout regulators from Diodes Incorporated. The series focuses on providing reliable linear regulation in small form factors. The AP7368D variant specifically denotes the single-output configuration with fixed voltage options. It serves as a power management integrated circuit (PMIC) solution for general-purpose voltage regulation tasks in consumer and industrial electronics.

Special Purpose Regulators Replacement Considerations

Check Diodes Incorporated datasheets for other AP7368 variants with different fixed output voltages if 1.2 V is not required. Verify pin compatibility before substituting with other manufacturers' 1 A LDOs in the X1-DFN1612-8 package. Ensure replacement parts meet the same 80 dB PSRR and 110 uA quiescent current specifications for equivalent noise and efficiency performance.
