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

Verify the specific suffix 'AB' indicates the ±1% output voltage accuracy class rather than the standard ±2% variant. Confirm the DPAK package designation matches your PCB footprint requirements. Check current lifecycle status as older revisions may be discontinued or subject to last-time buy constraints.

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

Select this model when precise 12V regulation with tight tolerance is required compared to the C-series variants. Ensure the application demands surface-mount assembly compatible with the DPAK form factor. Validate that the 250mA load current does not exceed thermal dissipation limits without adequate heatsinking.

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

This component belongs to the L4931 family of very low drop regulators designed for low power consumption. The family offers multiple output voltages and packages including SO-8, TO-92, and DPAK. The AB suffix specifically denotes higher precision manufacturing tolerances for critical analog or digital supply rails.
