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

Verify the specific ordering suffix '13' corresponds to the SOT-89 package and tape & reel packing quantity of 2,500 units as defined in the manufacturer's ordering information. Confirm that the application environment remains within the recommended operating junction temperature range of -40°C to +125°C. Ensure proper PCB layout practices are followed, particularly regarding the connection of the ground pin and placement of input/output capacitors to maintain stability and thermal performance.

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

Select this component when a fixed 5V output is required from a high-voltage input source up to 60V. It is appropriate for designs needing low standby power consumption due to its 2µA quiescent current. Consider the SOT-89 package size and thermal resistance characteristics for heat dissipation requirements. Verify that the load current does not exceed the 150mA maximum rating and that the dropout voltage specifications align with the minimum input voltage constraints of the system.
