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

Verify the specific package variant (SOT-89-3, TO-92, or SOT-23-3) required for your design, as the HT73XX-A series spans multiple form factors. Confirm that the input voltage does not exceed the 12V maximum rating during operation. Ensure thermal management aligns with the specified operating temperature range of -25°C to 70°C. Cross-reference the manufacturer part number HT7336-A with official UMW documentation to ensure component authenticity and compliance with RoHS3 standards.

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

Select the HT7336-A when a stable 3.6V rail is needed from inputs up to 12V with minimal static power draw. The low dropout characteristic makes it suitable for battery applications where maintaining output stability near the end of discharge is critical. Consider the available package options based on PCB space constraints and thermal dissipation requirements. Verify that the load current remains within the 250mA limit to ensure proper regulation and prevent overheating.

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