SPX5205
SPX5205 is Low-Noise LDO Voltage Regulator manufactured by MaxLinear.
Description
The SPX5205 is a positive voltage regulator with very low dropout voltage, output noise and ground current (750μA at 100m A). VOUT has a tolerance of less than 1% and is temperature pensated. Fixed output voltages 1.8V, 3.0V, 3.3V, and 5.0V and an adjustable version are available in a small 5-pin SOT-23 package. Other key features include zero off-mode current, reverse battery protection, thermal shutdown and current limit. The SPX5205 is an excellent choice for use in batterypowered applications, and where power conservation is desired such as: cellular/ cordless telephones, radio control systems and portable puters.
