1.2A CMOS Super LDO Voltage Regulator with EN CYT6220 Features 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 1.0µF. Standard voltage versions are 3.3V, 3.0V, and adjustable output from 1.25V to 4.5V. Typical 100mV Dropout Voltage at 500mA. Fast Enable Turn-On Time of 20µs (Typ.) Excellent Line and Load Regulation. High Accuracy Output Voltage of 2%. Ultra-Low Ground Current at 50µA (Typ.) Disable Current Less than 0.2µA (Typ.) Thermal and Over-Current Protection. Standard SOP-8 Package. Application USB removable devices MPEG4 devices Wireless LAN’s Hand-Held Instrumentation.
