ACE520 - Dual 300mA High PSRR Linear Regulator

Description

ACE520 dual, low-noise, low-dropout regulator delivers at least 300mA of continuous output current.

The output voltage for each regulator is set independently by trimming.

Output voltages are selectable in 100mV steps within a range of 1.2V to 3.5V.

Features

  • Two low dropout voltage regulators.
  • 300mA output current for each LDO.
  • 25uA operating supply current per LDO.
  • Low 47uV.

ACE520 Dual 300mA High PSRR Linear Regulator Description ACE520 dual, low-noise, low-dropout regulator delivers at least 300mA of continuous output current. The output voltage for each regulator is set independently by trimming. Output voltages are selectable in 100mV steps within a range of 1.2V to 3.5V. Typical output noise is 47uVrms,and PSRR is 73dB at 100Hz. The ACE520 includes two independent logic-controlled shutdown inputs and allows the output of each regulator to be turned of independently. The ACE520 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. The ACE520 has excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system.
