Diodes Incorporated AP7365-30YG-13

Overview

AP7365-30YG-13 from Diodes Incorporated is a fixed-output 3.0V, 600mA low-dropout linear regulator in SOT89 package with 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It delivers stable power to FPGA I/O rails, notebook CPU cores, and battery-powered consumer electronics requiring fast transient response and ultra-low standby consumption.

For engineers reviewing the AP7365-30YG-13 datasheet, AP7365-30YG-13 pinout, AP7365-30YG-13 application, or AP7365-30YG-13 equivalent, this page provides verified technical context, package-specific pin mapping, real-world application constraints, and validated alternative options for low-power LDO selection in portable and embedded systems.

Technical Context

The AP7365-30YG-13 implements a PMOS pass transistor architecture enabling 300mV dropout at 600mA output while maintaining 35μA quiescent current across 2V–6V input range. Its internal 0.8V bandgap reference and error amplifier support ±2% output accuracy over –40°C to +85°C ambient.

It integrates active-high enable logic (VIH = 1.4V, VIL = 0.4V), thermal shutdown at +145°C with +15°C hysteresis, and current limiting at 1.4A (short-circuit clamp at 240mA). Stability is guaranteed with ≥1μF ceramic output capacitor and ESR >15mΩ.

FAQ

What is the minimum input voltage required for AP7365-30YG-13 to maintain regulation at 600mA?

The minimum input voltage is 3.3V, calculated as VOUT + VDROPOUT = 3.0V + 0.3V. At 600mA load and 25°C ambient, the device sustains regulation down to this level per datasheet Figure 7 (Dropout vs. Output Current). Below 3.3V, output voltage drops nonlinearly and may fall outside ±2% tolerance.

Can AP7365-30YG-13 operate without an output capacitor?

No. The device requires a minimum 1μF ceramic output capacitor with ESR >15mΩ for stability, as confirmed in Section 8 (Application Information) of DS32260 Rev. 11-3. Omitting it causes oscillation and uncontrolled voltage overshoot during load transients, risking downstream IC damage.

Is the EN pin internally pulled up or does it require external biasing?

The EN pin has no internal pull-up; it must be actively driven to ≥1.4V for turn-on or ≤0.4V for shutdown. If unused, datasheet Section 9 specifies tying EN directly to IN to ensure permanent enable - floating EN risks undefined state and intermittent operation.

How does thermal performance differ between SOT89 and U-DFN2020-6 packages for AP7365-30YG-13?

AP7365-30YG-13 uses SOT89 (Y package), which has θJA = 133°C/W. In contrast, the U-DFN2020-6 variant (e.g., AP7365-30SNG-7) achieves θJA = 132°C/W - nearly identical thermal resistance. However, SOT89's exposed tab on pin 3 offers superior mechanical mounting and heatsinking flexibility in manual assembly or low-layer PCBs.
