ADP2119ACPZ-R7

ADP2119 is a low quiescent current, synchronous, step-down DC to DC regulator. This device uses a current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. Under light load conditions, it can be configured to operate in a pulse frequency modulation (PFM) mode, which reduces switching frequency to save power. It supports input voltages from 2.3V to 5.5V. It requires minimal external parts and provide a high efficiency solution with their integrated power switches, synchronous rectifiers, and internal compensation. Other key features include undervoltage lockout (UVLO), integrated soft start to limit inrush current at start-up, overvoltage protection (OVP), overcurrent protection. It is used in application such as point of load conversion, communications and networking equipment, industrial and instrumentation, consumer electronics, medical applications etc.
