Diodes Incorporated AP7365-10EG-13

Overview

AP7365-10EG-13 from Diodes Incorporated is a fixed-output 1.0V, 600mA low-dropout linear regulator with 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It operates from 2V to 6V input, delivers ±2% output accuracy across –40°C to +85°C, and supports fast 200μs startup-ideal for FPGA core power and battery-powered portable electronics requiring stable low-voltage bias.

For engineers reviewing the AP7365-10EG-13 datasheet, AP7365-10EG-13 pinout, AP7365-10EG-13 application, or AP7365-10EG-13 equivalent, key selection criteria include dropout voltage under 600mA load, thermal shutdown threshold at +145°C, PSRR of 65dB at 1kHz, and compatibility with 1μF ceramic output capacitors without minimum load requirements.

Technical Context

The AP7365-10EG-13 implements a PMOS pass transistor architecture enabling low dropout and high PSRR. Its internal 0.8V bandgap reference feeds an error amplifier that regulates output by adjusting gate drive to maintain fixed 1.0V output regardless of line or load variation within specified limits.

Enable logic (VIH = 1.4V, VIL = 0.4V) directly controls the pass element via a dedicated EN pin, while built-in current limit (~1.4A), short-circuit protection (~240mA), and thermal shutdown (+145°C trip, +130°C hysteresis) operate independently of external components to ensure fault resilience.

FAQ

What is the maximum input voltage for AP7365-10EG-13?

The absolute maximum input voltage is 6.5V, but the recommended operating range is 2V to 6V. Exceeding 6V risks permanent damage due to internal ESD structure limits and gate oxide stress in the PMOS pass element. Operation above 6V voids warranty and may trigger immediate failure even with brief transients.

Can AP7365-10EG-13 operate without an output capacitor?

No. The device requires a minimum 1μF ceramic output capacitor with ESR >15mΩ for stability. Omitting it causes oscillation, excessive output ripple, and potential thermal runaway under load. The capacitor must be placed within 2mm of the OUT and GND pins using short, wide traces per layout guidelines in DS32260 Rev. 11.

Is the EN pin internally pulled up or down?

The EN pin has no internal pull-up or pull-down resistor. It must be actively driven to ≥1.4V for enable or ≤0.4V for disable. Leaving it floating results in undefined operation-typically partial turn-on with unpredictable current draw and possible thermal stress. Tie to IN or use a dedicated GPIO with verified logic levels.

Does AP7365-10EG-13 support adjustable output voltages?

No. AP7365-10EG-13 is a fixed 1.0V output variant. Adjustable versions (e.g., AP7365-ADJWG-7) exist only in SOT25 and U-DFN2020-6 packages and require external resistor dividers. This part's internal feedback network is trimmed and laser-fused at wafer test to deliver precise 1.0V without external components.
