AP7315-185SA-7

Overview

The AP7315-185SA-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a nominal output voltage of 1.85V. It operates within an input voltage range of 1.7V to 5.25V and guarantees a maximum output current of 150mA. The device features high ripple rejection of 75dB at 1kHz and low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is specified as low as 35µA. It utilizes SOT23 packaging and includes integrated current limit and enable control circuitry.

Feature Summary

CMOS-based architecture with integrated resistor network for fixed output voltage accuracy
High power supply ripple rejection and ultra-low output noise suitable for sensitive subsystems
Integrated enable pin allowing precise on/off control and shutdown mode operation
Built-in short-circuit protection and thermal management capabilities

Applications

Smartphones and tablet devices
RF power supply circuits
Portable video players
Wireless communication adapters
Camera modules

Procurement Notes

Verify the specific ordering suffix SA confirms the SOT23 package type and standard non-discharge configuration. Confirm the -185 designation matches the required 1.85V output level. Ensure compliance with RoHS and halogen-free requirements if mandated by your design specifications. Cross-reference the datasheet revision against your manufacturing standards.

Selection Notes

Select this component when a stable 1.85V rail is needed from lithium-ion battery sources or similar low-voltage inputs. The low quiescent current makes it appropriate for battery-operated portable electronics. Verify that the load current does not exceed the guaranteed 150mA limit and that the input voltage remains within the 1.7V to 5.25V operational window.

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 characterized by high PSRR and low noise, targeting applications requiring clean power delivery in compact form factors like SOT23 and X2-DFN1010-4 packages.
