The EC8812 series of fixed output ultra low dropout linear regulators are designed for portable battery powered pplications, which require low power consumption and low dropout voltage.
Each device contains a bandgap voltage reference, an error amplifier, a PMOS power transistor, and current limit and temperature limit protection circuits.
The EC8812 is designed to work with low cost electrolytic and ceramic capacitors and requires a minimum output capacitor of 10μF.
