Diodes Inc.’s Dual LDO Offers High PSRR and Low Quiescent Current

April 10, 2019 Alix Paultre

Diodes Incorporated announced the AP7345D family of dual low-dropout (LDO) voltage regulators, with a high-power supply rejection ratio (PSRR) and low quiescent current. The AP7345D offers independent voltage input with an enable pin for controlling the output, for more flexibility. 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 AP7345D family features a PSRR of 75dB at 1kHz across the full output voltage range. The input voltage range extends from 1.7V to 5.25V and each of the two channels can deliver up to 300mA. 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 percent. With such a comprehensive range, the AP7345D family can address a wide variety of battery-powered applications. The AP7345D is supplied in an X2-DFN1612-8 package, providing a small PCB footprint to enable high levels of power density.
