Overview
The ADP7102ACPZ-R7 is a CMOS, low dropout linear voltage regulator (LDO) produced by Analog Devices Inc. This regulator is designed to operate from an input voltage range of 3.3 V to 20 V and can provide up to 300 mA of output current. It is particularly suited for high-performance analog and mixed-signal circuits, offering excellent line and load transient response, high power supply rejection ratio (PSRR), and low noise characteristics.
The ADP7102ACPZ-R7 is available in an 8-lead, 3 mm × 3 mm LFCSP (Wafer Level Chip Scale Package) with an exposed pad, which provides a compact solution and excellent thermal performance.
