AP7350-185CF4-7

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

The AP7350-185CF4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a stable 1.85V output with a maximum current of 150mA. The device operates within an input voltage range of 2.0V to 5.25V and maintains an output voltage accuracy of ±1%. Key electrical characteristics include a quiescent current as low as 0.25µA, a standby current of 0.02µA, and a typical dropout voltage of 0.32V at full load. The component is housed in an X2-WLB0606-4 wafer level chip scale package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix CF4 corresponds to the X2-WLB0606-4 package when sourcing. Confirm whether the non-discharge variant (AP7350) or discharge variant (AP7350D) is required, as this affects the part number. Ensure EN pin connections are strictly defined to avoid floating states during operation. Check datasheet thermal derating curves for high ambient temperatures.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for applications requiring minimal board space and ultra-low power consumption. The 1.85V output is fixed; verify compatibility with downstream loads. Consider the AP7350D variant if active output discharge is needed to pull VOUT to ground upon shutdown. Ensure input capacitors are placed close to the VIN and GND pins to maintain stability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the AP7350 series of 150mA LDOs from Diodes Incorporated. It utilizes a CMOS process technology optimized for low current consumption. The series offers various fixed output voltages ranging from 1.2V to 4.5V. All variants share the same miniature X2-WLB0606-4 package and similar electrical performance profiles regarding quiescent current and dropout voltage.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

The AP7350D-185CF4-7 serves as a direct functional substitute featuring built-in output discharge. Other Diodes Incorporated AP7350 variants with different output voltages may be used if the voltage requirement changes. Cross-manufacturer replacements require verification of pinout compatibility, package dimensions, and electrical parameters such as dropout voltage and quiescent current.
