AP7347D-12W5-7

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

The AP7347D-12W5-7 is a low-dropout regulator manufactured by Diodes Incorporated, featuring a fixed 1.2V output voltage and a guaranteed maximum output current of 500mA. It operates within an input voltage range of 1.7V to 5.5V and maintains high output voltage accuracy of ±1%. The device incorporates a CMOS process with a quiescent current as low as 60µA and provides ripple rejection of 75dB at 1kHz. Packaged in the SOT25 (Type A1) form factor, it includes thermal shutdown and short-circuit protection mechanisms.

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

Verify that the ordering suffix W5 corresponds specifically to the SOT25 package type rather than alternative packages like W-DFN2020-6. Confirm the internal code matches the required 1.2V output designation. Ensure compliance with RoHS standards and check for any specific automotive-grade variants if operating conditions require higher reliability thresholds.

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

Select this component when a stable 1.2V rail is required from a single-cell lithium-ion or similar power source. The wide input voltage range accommodates varying battery states. Consider the SOT25 footprint constraints and ensure adequate PCB copper area is allocated for thermal dissipation given the package's thermal resistance characteristics under load.
