AZ1117BH-2.5TRE1

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

The AZ1117BH-2.5TRE1 is a positive fixed linear regulator from the AZ1117 series by Diodes Incorporated, housed in an SOT-223-3 package. It provides a fixed output voltage of 2.5V with a maximum output current of 1A. The device supports input voltages up to 15V and features a typical dropout voltage of 1.25V at full load. Key electrical characteristics include a quiescent current of 10 mA and a power supply rejection ratio (PSRR) of 75 dB at 120 Hz. It operates within a junction temperature range of -40°C to +125°C and includes thermal shutdown protection.
