AP7368D-28RS4-7

Special Purpose Regulators Overview

The AP7368D-28RS4-7 is a fixed-output low dropout (LDO) voltage regulator manufactured by Diodes Incorporated. It provides a stable 2.8 V output with a maximum continuous current of 1 A. The device operates within an input voltage range of 1.7 V to 5.5 V and features a typical dropout voltage of 240 mV at full load. Quiescent current is specified at 110 uA, ensuring efficient power management in battery-powered applications. It offers high power supply rejection ratio (PSRR) of 80 dB and maintains line regulation of 0.02 %/V. The component is housed in an X1-DFN1612-8 surface-mount package and supports operation from -40°C to +85°C.

Special Purpose Regulators Procurement Notes

Verify that the specific suffix RS4-7 corresponds to the required packaging configuration and tape-and-reel quantity. Confirm the fixed 2.8 V output voltage matches the target circuit design requirements. Ensure the X1-DFN1612-8 footprint aligns with the PCB layout specifications before finalizing procurement orders.

Special Purpose Regulators Selection Notes

Select this component when a fixed 2.8 V output is required with 1 A current capacity. Consider the 110 uA quiescent current for standby power constraints. Verify that the 5.5 V maximum input voltage suits the source supply. The X1-DFN1612-8 package size should fit the available board space constraints.
