MaxLinear | SPX5205M5-L-3-3/TR

The SPX5205M5-L-3-3/TR is a positive voltage  regulator with very lowdropout voltage, output noise and ground current (750 μA at 100mA). VOUT has atolerance of less than 1% and is temperature compensated. Fixed output voltages1.2 V, 1.5 V, 1.8 V, 2.0 V, 2.5 V, 2.8 V, 3.0 V, 3.3 V, and 5.0 V and anadjustable version are available in a small 5-pin SOT-23 package.

The other key features include zero off-mode current, reverse batteryprotection, thermal shutdown and current limit. The SPX5205 is an excellentchoice for use in batterypowered applications, and where power conservation isdesired such as: cellular/ cordless telephones, radio control systems, andportable computers.
