Its PSRR starts at 88 dB at 10 kHz and rolls off to 50 dB at 1 MHz. Maximum dropout is 0.42 V at the full 200 mA load. The enable and soft-start control features let you sequence the rail on power-up and limit inrush current into capacitive loads. ## Package and thermal handling Housed in an 8-SOIC with exposed pad (0.154\" body width, 3.90 mm), the ADP7118ARDZ-3.3 relies on the pad for heat sinking. Solder the exposed pad to a copper plane on the PCB — the thermal resistance drops significantly versus the standard SOIC-8 without a pad. The -40 to 125 °C operating range covers industrial and automotive auxiliary-supply environments. Protection features include over-current and over-temperature shutdown.","metaTitle":"ADP7118ARDZ-3.3 Linear Regulator, 3.3V Fixed Output, 200mA","metaDescription":"ADI ADP7118ARDZ-3.3 LDO regulator: 3.3V fixed output, 200mA, PSRR 88dB~50dB (10kHz~1MHz), dropout 0.42V max at full load, -40 to 125°C.
