AP7331-30SNG-7

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

The AP7331-30SNG-7 is a fixed-output linear regulator providing 3.0V at up to 300mA in a DFN2020-6 package. It operates with an input voltage range of 2V to 6V and features a typical quiescent current of 65µA at full load. The device includes an enable pin, low dropout voltage of 300mV at 300mA, and fast start-up time of 80µs. It offers PSRR of 65dB at 100Hz and stability with 1µF ceramic output capacitors. Protection circuits include current limit, short circuit, and thermal shutdown.

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

Verify the specific suffix SNG confirms the DFN2020-6 package and 3.0V fixed output configuration. Ensure compatibility with RoHS compliance requirements as indicated by the Green molding compound designation. Confirm that the tape and reel packaging quantity aligns with manufacturing needs. Cross-reference the datasheet revision to ensure all electrical characteristics match design specifications.

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

Select this component when a stable 3.0V rail is required from a 2V to 6V source with minimal ground current draw. The DFN2020-6 package is ideal for space-constrained designs requiring efficient heat dissipation. Consider the 300mA output capability and low dropout performance for systems where input voltage may approach the output level. The enable pin allows for system-level power sequencing or standby mode control.

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

This part belongs to the AP7331 family of low dropout regulators from Diodes Incorporated. The series offers both adjustable and fixed output options in SOT25 and DFN2020-6 packages. The AP7331-30 variant specifically provides a fixed 3.0V output, distinguishing it from adjustable models or other fixed voltage versions within the same product line.

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

Direct substitutes within the AP7331 family include AP7331-33SNG-7 for 3.3V output or AP7331-ADJSNG-7 for adjustable output, provided the voltage requirement changes. Other manufacturers' LDOs with similar 300mA current, 3.0V output, and DFN2020-6 packaging may be considered if electrical parameters like dropout voltage and quiescent current are comparable.
