AP7345D-2828RH4-7

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AP7345D-2828RH4-7 is a dual low dropout regulator from Diodes Incorporated, packaged in an X2-DFN1612-8 footprint. It provides two independent channels with fixed output voltages of 2.8V each. Each channel guarantees an output current of 300mA and operates within an input voltage range of 1.7V to 5.25V. The device features high ripple rejection of 75dB at 1kHz and low output noise of 60µVrms across the 10Hz to 100kHz bandwidth. Quiescent current is specified as low as 50µA per channel.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How does the enable pin function on the AP7345D?

Each channel has a dedicated enable pin (EN1 and EN2). Driving the pin high activates the respective regulator output, while pulling it low shuts down the channel.

What is the maximum input voltage for this regulator?

The recommended operating input voltage range is 1.7V to 5.25V. The absolute maximum rating allows up to 6.0V.
