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

Verify the specific suffix 'ACM' indicates the commercial grade variant and 'X' denotes tape-and-reel packaging. Confirm the '-3.3' designation aligns with your required fixed or adjusted output configuration against the datasheet's adjustable specifications. Ensure the NOPB suffix confirms lead-free and RoHS compliance status prior to final procurement authorization.

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

Select this component when a wide input voltage range up to 30 V is required alongside low power consumption. The 100 mA output capacity suits moderate load applications. The SOIC-8 package facilitates surface-mount assembly. Verify that the 380 mV dropout voltage meets the minimum headroom requirements for the specific input-output differential in the target circuit design.
