CYT 6220 1.5A COMS Super LDO Voltage Regulator Features General Description The CYT6220 series of fixed output low 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 0.8V 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 120µA (Typ.) Disable Current Less than 0.1µA (Typ.) Thermal and Over-Current Protection.
