Ultra LDO 2A Linear Regulator AIC1221-33GY3TR
A low noise, high PSRR and ultra low dropout
linear regulator AIC1221 is optimized for low ESR
ceramic capacitors operation with 2A continuous
current. The AIC1221 is designed for portable and
wireless devices with demanding performance
and space requirements.
• Guaranteed 2A Output Current.
• Fast Response in Line/Load Transient.
• Wide Operating Voltage Ranges: 1.8V to 6V.
• 0.01μA Shutdown Standby Current.
• Low Quiescent Current: 30μA.
• Fixed: 3.3V Output Voltage.
• Low Dropout：550mV at 2A and 3.3V output
voltage, 480mV at 2A and 5V output voltage.
• High PSRR：70dB at 1kHz.
• Active Low or High Shutdown Control. Current
Limit and Thermal Protection.
• Available in ±2% Output Tolerance.
• Available in SOT-223
Compatible with the LM3940 in SOT223.
AIC1221-33GY3TR has a better "Quiescent current" and only +/- 2% output tolerance and a maximum current output of 2A.
