Dual LDO offers high power supply rejection ratio
The AP7345D offers independent voltage input with an enable pin for controlling the output. This provides for more flexibility when designing the power source for applications. Each channel switches off or on within approximately 10µs of the EN pin changing state, while the EN pin on each channel can also be tied high if output control is not required. The devices feature an excellent PSRR of 75dB at 1kHz, across the full output voltage range. Input voltage range extends from 1.7V to 5.25V and each of the two channels can deliver up to 300mA, guaranteed. The inclusion of short-circuit protection ensures the LDO does not sustain damage in the event of a short circuit on either of the output voltage rails. The family comprises 22 devices covering a range of fixed dual-input/dual-output voltages between 1.2V and 3.6V, with an accuracy of ±1%. The AP7345D comes in an X2-DFN1612-8 package.
