300mA Low Power Low Noise LDO CMOS Voltage Regulator Description The SE5509 series of fixed output low dropout linear regulators are designed for portable battery powered applications, which require low power consumption, low noise environment, and low dropout voltage. Each device contains a bandgap voltage reference, an error amplifier, a PMOS power transistor, and resistors for setting output voltage, and current limit and temperature limit protection circuits. The SE5509 has been designed to be used with low cost capacitors and requires a minimum output capacitor of 1.0μF. The output voltages range from 1.3V to 4.4V in 100mV increments. Standard voltage versions are 1.5, 1.8, 2.5, 2.8, 3.0, and 3.3V. SE5509 Features ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ Typical 200mV Dropout Voltage at 150mA.
