The ADP220ACBZ-2818R7 from Analog Devices is a dual, 200 mA low dropout voltage regulator designed for applications requiring high performance and low noise. It features an input voltage range of 2.5 V to 5.5 V and provides two independent regulated outputs.
Key electrical specifications include a low dropout voltage of 150 mV at a 200 mA load, high Power Supply Rejection Ratio (PSRR) up to 76 dB at 1 kHz, and low output noise of 27 µV rms. The device operates with a typical ground current of 60 µA at no load, contributing to extended battery life in portable devices.
This regulator is available in a miniature 6-ball WLCSP package, making it suitable for space-constrained designs. It includes overcurrent and thermal protection features, along with logic-controlled enables for independent output control. The ADP220ACBZ-2818R7 is stable with 1 µF ceramic output capacitors and does not require a noise bypass capacitor.
Applications include mobile phones, digital cameras, portable medical devices, and battery-powered equipment where efficient and clean power delivery is critical. The device operates over a junction temperature range of -40°C to 125°C.
