The ADP7104ARDZ-5.0-R7 is a low dropout (LDO) regulator in 8 pin SOIC-8_EP_150mil RoHS package manufactured by Analog Devices. It is used to provide a low noise, low dropout voltage source of 5V from an input voltage range of up to 21V. This LDO regulator contains a power field-effect transistor (FET) to achieve low quiescent current and requires an external bypass capacitor to stabilize the output voltage. It has a maximum load current of 1A, output voltage accuracy of ±2.5%, optimized line regulation of 0.05%/V, temperature power offset of 11mV/°C and guaranteed shutdown current of 0.1uA. The device also features internal current limiting and thermal protection for over-temperature use.
