Core Voltage Regulator
The OT1104 is a CMOS 75mA on-chip core voltage regulator designed for use when a pin for an external decoupling capacitor is not available.
A source follower output stage provides a low impedance at the output at high frequencies, minimizing on chip decoupling requirements for core logic.
