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

Verify part status as obsolete before procurement planning. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics. Ensure the SOT-23-5 package matches your PCB footprint. Validate that the 2.7V fixed output meets your circuit requirements since adjustable alternatives are not available for this specific suffix.

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

Select this component when a precise 2.7V rail is required with minimal board space. The SOT-23-5 package suits compact layouts. Consider the 150mA limit for load demands. The enable feature allows system-level power sequencing. Verify input voltage does not exceed 6.5V. Thermal performance must be assessed based on ambient conditions and PCB copper area for heat dissipation.
