ACE535C (VER1.1)

ACE535C
300mA High PSRR, Fast Response Linear Regulator
Description
ACE535C series is a group of positive voltage output, low power consumption, low dropout
voltage regulator.
ACE535C can provide output value in the range of 1.0V~4.5V every 0.1V step. It also can be
customized on command.
ACE535C includes high accuracy voltage reference, error amplifier, current limit circuit and output driver
module with discharge capability.
ACE535C has excellent load and line transient response and good temperature characteristics, which
can assure the stability of chip and power system. And it uses trimming technique to guarantee output
voltage accuracy within ±2%.
ACE535C is available in SOT23-5 and DFN1x1-4 packages which are lead free.

Note:
1)Heat Sink Area of PCB for DFN1x1-4 is recommended at least 2.5mmx4mm.
2) Package Thermal Resistance value can be affected by PCB design, outside radiator, ambient airflow, operating power, it just
shows for reference.
3) Exceed these limits to damage to the device.
4) Exposure to absolute maximum rating conditions may affect device reliability
