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

Verify the specific suffix 'B' indicates the correct 3.7V output voltage variant during procurement. Confirm the 'P' suffix corresponds to the SOT-89-5 package type required for your PCB layout. Ensure compliance with RoHS directives if applicable to your manufacturing region. Cross-reference the manufacturer part number directly with official Torex documentation to avoid substitution errors.

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

Select this component when a stable 3.7V rail is required from a single-cell lithium battery or similar source. The low dropout characteristic allows efficient regulation even as battery voltage drops near the output level. The high speed response and ripple rejection make it suitable for sensitive RF or digital logic loads. Verify that the thermal dissipation in the SOT-89 package can handle the expected power loss under maximum load conditions.
