ADP3605:  120 mA Switched Capacitor Voltage Inverter with Regulated Output

Product Description

The ADP3605 is a 120 mA inverting regulator that converts a 3- to 6-volt input into a -3 volt output. It provides a fully regulated output voltage without using inductors. A charge pump converter, the ADP3605 combines the benfits of outstanding accuracy (±5% over line, load and temperature), low shutdown current (10 µA typical) and small size. It has an internal 500 kHz oscillator, allowing use of small charge pump and filter capacitors.

Features

  • Fully Regulated Output Voltage (–3 V and Adjustable)
  • High Output Current: 120 mA
  • Output Accuracy: 63%
  • 250 kHz Switching Frequency
  • Low Shutdown Current: 2 µA Typical
  • Input Voltage Range from 3 V to 6 V
  • SO-8 and RU-14 Packages
  • –40°C to +85°C Ambient Temperature Range
