SPX5205

150mA Low-Noise LDO Voltage Regulator

Description

The SPX5205 is a positive voltage regulator with very low dropout voltage, output noise and ground current (750μA at 100mA). VOUT has a tolerance of less than 1% and is temperature compensated. Fixed output voltages 1.2V, 1.8V, 2.5V, 2.8V, 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 battery powered applications and where power conservation is desired, such as cellular/cordless telephones, radio control systems and portable computers.
