AP7315-26SA-7

Overview

The AP7315-26SA-7 is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed output voltage of 2.6V and housed in an SOT23 package. It supports an input voltage range from 1.7V to 5.25V and guarantees an output current of 150mA. The device provides high ripple rejection of 75dB at 1kHz and maintains low output noise of 60µVrms across the 10Hz to 100kHz bandwidth. Quiescent current is specified as low as 35µA, with standby current reaching 0.01µA when disabled. Output voltage accuracy is maintained within ±1% at room temperature.

Feature Summary

• CMOS-based architecture providing high output voltage accuracy and low on-resistance for efficient power management.
• Integrated enable pin allows precise control over regulator operation, supporting active shutdown modes to minimize standby power consumption.
• Built-in short circuit protection clamps output current during fault conditions to prevent thermal damage and ensure component safety.

Applications

• Smart Phone/PAD
• RF Supply
• Cameras
• Portable Videos
• Wireless Communication

Procurement Notes

Verify that the ordering suffix SA corresponds specifically to the SOT23 package configuration required for your PCB layout. Confirm the -7 suffix indicates tape and reel packaging if automated assembly is planned. Ensure the fixed 2.6V output aligns with system requirements, as other voltage options exist within the AP7315 series. Check RoHS compliance status against specific regional regulatory needs before finalizing procurement orders.

Selection Notes

Select this component when a stable 2.6V rail is needed from lithium-ion battery sources or similar variable inputs. The SOT23 package suits space-constrained designs requiring surface mount technology. Consider the 150mA current limit for moderate load applications. Evaluate the 75dB ripple rejection capability for noise-sensitive analog or RF circuits where clean power delivery is critical for signal integrity.

Part Context

This part belongs to the AP7315 family of low dropout regulators designed for portable electronics. The series offers various fixed output voltages ranging from 1.1V to 3.3V. Different package options including X2-DFN1010-4, SOT25, and SOT23 are available to accommodate diverse footprint constraints. The non-discharge variant lacks internal output discharge resistors upon shutdown.

Replacement Considerations

AP7315-26SR-7 serves as a direct functional replacement offering identical electrical characteristics but utilizes the SR package variant instead of SA.
