AZ78L09ZTR-G1

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

The AZ78L09ZTR-G1 is a three-terminal positive linear regulator from the AZ78LXX series, manufactured by Diodes Incorporated. It provides a fixed output voltage of 9V with an output current capability up to 100mA. The device operates within an input voltage range of 12V to 18V and maintains line regulation between 18mV and 75mV. Load regulation ranges from 20mV to 90mV under specified conditions. The dropout voltage is typically 1.6V. Quiescent current is 3mA to 5mA, and ripple rejection at 120Hz is 38dB to 44dB. It features internal short-circuit current limiting and thermal overload protection.
