AZ78L05ZTR-E1

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

The AZ78L05ZTR-E1 is a three-terminal positive linear regulator from the AZ78LXX series, manufactured by Diodes Incorporated. It provides a fixed output voltage of 5V with an output current capability up to 100mA. The device operates within an input voltage range of 7.0V to 15V and maintains an output voltage tolerance of ±5% over the full temperature range (-40°C to +125°C). Key electrical parameters include a typical quiescent current of 3mA, a dropout voltage of 1.6V, and ripple rejection of 47dB to 62dB at 120Hz. It features internal short-circuit current limiting and thermal overload protection.
