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

Verify the specific suffix 'B' indicates the absence of an auto discharge function at the off state. Confirm the 'T1' designation corresponds to the SOT-89-5 package type. Ensure compatibility with ceramic capacitors of 1.0µF or more as recommended for phase compensation and stability during operation.

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

Select this component when a fixed 0.7V output is required with up to 500mA load capability. Consider the SOT-89-5 package for higher power dissipation needs compared to smaller footprints. Evaluate the need for the non-discharge feature ('B' suffix) versus the discharge variant ('D' suffix) based on system power-down requirements.
