ACE513

ACE513
2A Linear Regulator
Description
ACE513 series are a group of positive voltage output, high precise, and low power consumption voltage
regulator. Voltages are selectable in 100mV steps within a range of 1.2V to 3.6V. It also can be
customized on command.
ACE513 series have 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%.
Features
• Low Quiescent Current: 26uA at 5V
• High PSRR: 60dB range to 1KHz
• Low Output Noise: 44uVRMS
• Low Dropout: 430mV at 1.5A load
• Maximum output current: 2.5A
• Highly Accurate: ±2%
• Low ESR Ceramic Capacitor Compatible
Application
• Reference Voltage Source
• Battery Powered Equipment
• PC Peripherals
• Wireless Devices
• Instrumentation
