Description

The AP7347DQ is a low dropout regulator with high output voltage accuracy, low RDS(on), high PSRR, low output noise, and low quiescent current. This regulator is based on a CMOS process. The AP7347DQ includes a voltage reference, error amplifier, current limit circuit, and an enable input to turn it on and off. With the integrated resistor network, fixed output voltage versions can be delivered. With its low power consumption and line and load transient response, the AP7347DQ is well-suited for low power handheld automotive equipment. The AP7347DQ is packaged in the SOT25 (Type A1) and WDFN2020-6 (wettable) packages, which allow for the smallest footprint and a dense PCB layout.

Feature(s)

  • Low VIN and Wide VIN Range: 1.7V to 5.5V
  • Guarantee Output Current: 500mA
