- Wireless Adapters
Procurement Notes
Verify the specific ordering suffix W5 corresponds to the SOT25 package configuration required for your design. Confirm that the non-discharge variant aligns with your system's power-down requirements. Ensure compatibility with RoHS 3 standards if applicable to your region. Validate that the 150mA output current meets the peak load demands of your target application circuit.
Selection Notes
Select this component when a stable 2.6V rail is needed for low-power portable electronics. The wide input voltage range accommodates single-cell battery operation. Consider the SOT25 footprint constraints against available PCB space. Evaluate the 35µA quiescent current impact on overall battery life in standby modes compared to higher consumption alternatives.
Part Context
This part belongs to the AP7315 series of low dropout regulators designed for handheld communication equipment. The series offers various fixed output voltages ranging from 1.1V to 3.3V. It is distinguished by its CMOS process technology which enables low power consumption and small physical size. The family supports dense PCB layouts through multiple package options including SOT23 and X2-DFN1010-4.

FAQ
What is the function of the EN pin?
The EN pin serves as the enable input. Driving it high turns the regulator on, while pulling it low activates shutdown mode. It must not be left floating.
Does this part include output discharge?
No, the AP7315-26W5-7 does not include built-in output discharge. The 'D' suffix indicates the discharge variant.
What is the typical ripple rejection performance?
The ripple rejection is typically 75dB at a frequency of 1kHz under standard test conditions.
