AS78L15ZTR-E1

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

The AS78L15ZTR-E1 is a three-terminal positive linear voltage regulator from the AS78LXX series by Diodes Incorporated. It provides a fixed 15V output with a maximum current of 100mA. The device operates within an input voltage range up to 36V and features internal short-circuit current limiting, thermal overload protection, and safe-area compensation. It utilizes a TO-92 package (TO-226AA) with ammo packing and supports through-hole mounting across a temperature range of -40°C to 125°C.

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

Verify that the ordering suffix 'E1' confirms lead-free compliance as specified in the datasheet. Confirm the 'Z' package designation corresponds to the TO-92 form factor and ensure the 'TR' suffix indicates ammo packing rather than tape and reel. Cross-reference the manufacturer part number against official Diodes Incorporated documentation to validate component authenticity and revision status.

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

Select this component for applications requiring a fixed 15V supply with moderate current demands up to 100mA. Ensure the input voltage remains within the 36V absolute maximum rating while accounting for power dissipation limits. Verify that the TO-92 package size accommodates the available board space and that through-hole assembly methods align with the manufacturing process requirements.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the AS78LXX series of 100mA positive voltage regulators manufactured by Diodes Incorporated. The series includes variants with different fixed output voltages such as 5V and 12V, packaged in TO-92, SOT-89, and SOIC-8 configurations.
