DESCRIPTION
The AIC1952 is a dual output linear regulator in a tiny SOT23-6, DFN-6 (2x2)package. It is optimized for low ESR ceramic capacitors operation and up to 300mA continuous current on each output.
The AIC1952 offers high precision output voltage of ±2%. At 300mA load current, a 200mV dropout is performed when output voltage is equal to 3.3V. The quality of low quiescent current and low dropout voltage makes this device ideal for battery power applications. The high ripple rejection and low noise of the AIC1952 provide enhanced performances for critical applications such as cellular phones, and PDAs.
The AIC1952 includes current limit and thermal shutdown protection. Each of the output is controlled independently.
