AZ1117CR-5.0TRG1

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

The AZ1117CR-5.0TRG1 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated, providing a nominal 5.0V output with a maximum continuous current of 800mA. It operates within an input voltage range up to 15V and features a typical dropout voltage of 1.3V at 800mA load. The device incorporates on-chip thermal shutdown and current limiting for protection. It maintains output voltage accuracy within ±1% and delivers a ripple rejection ratio of 70dB at 120Hz. The component functions reliably across a junction temperature range from -20°C to +125°C.
