Diodes Incorporated AP7362-HA-7

Overview

AP7362-HA-7 from Diodes Incorporated is a 1.5A adjustable-output ultra-low dropout linear regulator in U-DFN2030-8 package, featuring 190mV dropout at full load, ±1.5% V_ADJ accuracy at +25°C, and 0.5mA typical quiescent current. It delivers stable low-voltage power to FPGA I/O rails and ASIC cores in space-constrained embedded systems requiring fast transient response and thermal robustness.

For engineers reviewing the AP7362-HA-7 datasheet, AP7362-HA-7 pinout, AP7362-HA-7 application, or AP7362-HA-7 equivalent, key selection criteria include dropout voltage under 1.5A load, EN pin logic thresholds (VIH ≥1.4V, VIL ≤0.65V), ADJ pin bias current (≤750nA over temp), and thermal shutdown threshold (+170°C) for reliable operation in industrial ambient conditions.

Technical Context

The AP7362-HA-7 integrates a PMOS pass element with internal 0.605V reference and error amplifier, enabling adjustable output from 0.6V to 5.0V via external resistor divider. Its internal compensation eliminates ESR dependency, ensuring stability with any capacitor type including 10µF ceramic.

It implements active current limiting (3.6A peak, 3.7A short-circuit) and thermal shutdown with 10°C hysteresis, while maintaining 90° phase margin across no-load to 1.5A load conditions. The EN pin controls operation with 25µs turn-on/turn-off delay and 25nA shutdown ground current.

FAQ

What is the maximum input voltage for AP7362-HA-7?

The absolute maximum input voltage is 6.0V, but the recommended operating range is 2.2V to 5.5V. Exceeding 5.5V risks violating safe operating area limits even at light loads, and may trigger internal protection circuits. For 5V rail applications, ensure VIN does not surge beyond 5.5V due to line transients or hot-swap events.

Can AP7362-HA-7 operate without an external output capacitor?

No. An output capacitor is mandatory for stability and transient response. The device requires ≥10µF ceramic capacitance on the OUT pin, placed within 2mm of the package. Omitting it causes oscillation and unregulated output, as confirmed by gain-phase plots showing instability below 10µF in all tested configurations.

How does the ADJ pin function in the AP7362-HA-7?

The ADJ pin is the feedback node for adjustable-output operation, internally biased at 0.605V. A resistor divider (R1 from OUT to ADJ, R2 from ADJ to GND) sets VOUT = 0.605V × (1 + R1/R2). R2 must be ≤10kΩ to maintain reference accuracy; values above degrade VADJ tolerance to ±3% over temperature.

Is the exposed thermal pad on U-DFN2030-8 required to be grounded?

Yes-the exposed pad is electrically connected to the silicon die substrate and must be soldered to a GND copper pour. While not the sole ground path, omitting this connection increases θJA by >30°C/W, risking thermal shutdown at 1.2A load in still-air conditions per JEDEC JESD51-7 thermal characterization data.
