300mA Low Power Low Noise LDO
CMOS Voltage Regulator
Description
The SE5509B 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 SE5509B 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. The SE5509B is characterized for operation from -40 C
