Overview
The ADP2118ACPZ-1.0-R7, produced by Analog Devices Inc., is a low quiescent current, synchronous, step-down DC-to-DC regulator. It is designed in a compact 16-lead, 4 mm × 4 mm LFCSP package, making it ideal for space-constrained applications. This regulator uses a current mode, constant frequency pulse-width modulation (PWM) control scheme, ensuring excellent stability and transient response. It can also operate in pulse frequency modulation (PFM) mode under light loads to reduce power consumption.
