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

This component has reached end-of-life status and is no longer in active production by the manufacturer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific package variant and revision level, as obsolete parts may vary in condition. Due to the discontinuation, lead times are unpredictable, and long-term supply availability cannot be guaranteed for new manufacturing projects.

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

Engineers selecting this part should consider its fixed 5V output and 300mA current capability against their specific load requirements. The 20V maximum input voltage allows flexibility in higher-voltage bus architectures. Given the obsolete status, alternative components with similar electrical characteristics and compatible pinouts should be evaluated for new designs. Verify that the required operating temperature range and protection features align with the target application environment before finalizing the selection.
