CM3702 - Micropower Low-Noise Charge-Pump and Linear Regulator

General Description

The CM3702 low-noise charge pump LDO regulator is designed to provide accurate and “clean” power to a subsystem, e.g an audio codec, LED driver, or flash memory.

The 5V output provides up to 100mA continuous current for input voltages from 2.8V to 5.5V, and up to 200mA for a narrower range.

Key Features

  • Low noise regulator with integrated charge pump voltage-booster 5V output with input voltage as low as 2.8V Charge pump can also power external LDO Low noise in 20Hz to 20kHz audio band Up to 200mA continuous output current Low operating and shutdown currents Stable with low-ESR ceramic or tantalum capacitors 10-Lead MSOP and TDFN packages Lead-free finishing Block Diagram.
