AP7347D-15W5-7

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

The AP7347D-15W5-7 is a low-dropout regulator manufactured by Diodes Incorporated, featuring a fixed 1.5V output voltage and packaged in SOT25 (Type A1). It supports an input voltage range of 1.7V to 5.5V and guarantees a continuous output current of 500mA. The device incorporates CMOS technology with a quiescent current as low as 60µA and provides high ripple rejection of 75dB at 1kHz. It includes integrated short-circuit protection, thermal shutdown, and an enable pin for power control.

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

• Integrated enable pin allows precise power management by switching the regulator on or off via logic-level signals.
• Built-in short-circuit protection clamps output current during faults to prevent component damage.
• Thermal shutdown circuitry activates when junction temperature exceeds safe operating limits.
• Low noise design minimizes interference for sensitive analog and digital circuits.

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

Verify the specific suffix W5 corresponds to the SOT25 package type required for your PCB layout. Confirm that the 1.5V fixed output aligns with system voltage requirements. Ensure EN pin connections are properly biased to avoid floating states during operation. Check datasheet for thermal dissipation needs based on ambient conditions.

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

Select this part when a stable 1.5V rail is needed from a single-cell lithium battery or similar supply. The SOT25 package suits space-constrained designs requiring surface-mount assembly. Consider the 500mA current capability against peak load demands. Verify input voltage stability remains within the 1.7V to 5.5V operational window.

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

This component belongs to the AP7347D series of low-noise LDO regulators designed for automotive and consumer electronics. It shares features like high PSRR and low dropout with other variants in the family but differs in output voltage and package options. The standard version complements the automotive-compliant AP7347DQ series.

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

AP7347DQ-15W5-7 serves as the automotive-grade equivalent with enhanced reliability standards. Other AP7347D variants with different output voltages may be used if voltage levels match application needs. Cross-reference pinouts and thermal characteristics before substituting packages.
