1.2A CMOS Super LDO Voltage Regulator with EN Description The CYT6220 series of fixed output ultra lo w dropout linear regulators are designed for portable battery powered applications, which require low power consumption 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 CYT6220 has been designed to be used with low cost capacitors and requires a minimum output capacitor of 1.0F. 1.25V to 4.5V. Standard voltage versions are 3.3V, 3.0V, and adjustable output from CYT6220 Features Typical 100mV Dropout Voltage at 500mA. Fast Enable Turn-On Time of 20s (Typ.) Excellent Line and Load Regulation. High Accuracy Output Voltage of 2%. Ultra-Low Ground Current at 50A (Typ.) Disable Current Less than 0.2A (Typ.) Thermal and Over-Current Protection. Standard SOP-8 Package. Application USB removable devices MPEG4 devices Wireless LAN's Hand-Held Instrumentation.
