Diodes Incorporated AP7366EA-30SN-7

Overview

AP7366EA-30SN-7 from Diodes Incorporated is a fixed-output 3.0V, 600mA low-dropout linear regulator in U-DFN2020-6 package, featuring 60μA quiescent current, 300mV dropout at full load, 75dB PSRR at 1kHz, and integrated enable control. It delivers stable power to FPGA I/O rails and battery-powered microcontrollers where low standby consumption and fast transient response are critical.

For engineers reviewing the AP7366EA-30SN-7 datasheet, AP7366EA-30SN-7 pinout, AP7366EA-30SN-7 application, or AP7366EA-30SN-7 equivalent, this page provides verified technical context, validated pin functions, real-world application constraints, and confirmed alternative options for 3.0V LDO selection in space-constrained industrial and portable designs.

Technical Context

The AP7366EA-30SN-7 integrates a PMOS pass element with bandgap reference, error amplifier, and thermal shutdown circuitry. Its fixed 3.0V output is internally trimmed to ±1% accuracy over load and temperature, eliminating external feedback resistors.

It operates across 2.2V–6V input range with active-high EN control, supports 1μF ceramic output capacitance, and maintains regulation down to zero load. The U-DFN2020-6 package delivers 46.2°C/W junction-to-ambient thermal resistance for high-power-density layouts.

FAQ

What is the minimum input voltage required for AP7366EA-30SN-7 to maintain 3.0V regulation at 600mA?

The minimum input voltage is 3.3V, derived from the 300mV dropout specification at 600mA load. Below this, output voltage drops below 3.0V; operation is guaranteed only within the 2.2V–6V input range, but regulation at full load requires VIN ≥ VOUT + VDROPOUT = 3.3V. At lighter loads, lower input voltages are permissible.

Can AP7366EA-30SN-7 be used without an external output capacitor?

No. A minimum 1μF ceramic capacitor is mandatory between OUT and GND for stability, as confirmed in the Electrical Characteristics table and Application Information section. Omitting it causes oscillation and potential damage. Higher values improve transient response but are not required for basic regulation.

Is the ADJ pin functional in the AP7366EA-30SN-7 fixed-output variant?

No. In the fixed-output version, the ADJ pin is internally connected to the 0.8V reference and serves no external function. It is retained for pin compatibility with adjustable versions but must not be externally biased; leaving it floating or connecting it to GND has no effect on operation.

Does AP7366EA-30SN-7 require a specific PCB layout for thermal performance?

Yes. The U-DFN2020-6 package's exposed thermal pad must be soldered to a dedicated copper pour connected to ≥2 internal ground planes. Diodes recommends ≥25mm² of 2oz copper per the datasheet's thermal resistance model; insufficient copper area raises junction temperature and triggers thermal shutdown under sustained 600mA loads.
