AS78L05Z-E1

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AS78L05Z-E1 is a three-terminal positive linear voltage regulator from the AS78LXX series by Diodes Incorporated. It provides a fixed output voltage of 5V with an output current capability up to 100mA. The device features internal current limiting, thermal shutdown protection, and safe-area compensation for overload immunity. It operates within an input voltage range of up to 30V and maintains an output voltage accuracy of ±5% over the full temperature range. The component is housed in a TO-92 package (TO-226-3) designed for through-hole mounting.

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

Verify that the ordering suffix 'E1' confirms lead-free compliance and RoHS standards as specified by the manufacturer. Confirm the package type corresponds to the Z designation for TO-92 bulk packing. Ensure the part number matches the specific 5V output requirement and standard precision level rather than high precision variants.

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

Select this component when a fixed 5V output is required with moderate current demands up to 100mA. Consider the TO-92 through-hole package for prototyping or applications where surface mount options are unsuitable. Evaluate the thermal resistance characteristics if operating near maximum power dissipation limits under varying ambient temperatures.
