Product details
Overview
AP7363-12E-13 from Diodes Incorporated is a 1.5A ultra-low dropout linear regulator with fixed 1.2V output, 190mV dropout at full load, 0.5mA quiescent current, and thermal shutdown protection. It operates across 2.2V–5.5V input and delivers stable power to FPGA I/O rails and ASIC core supplies in space-constrained consumer electronics.
For engineers reviewing the AP7363-12E-13 datasheet, AP7363-12E-13 pinout, AP7363-12E-13 application, or AP7363-12E-13 equivalent, this page provides verified package mapping (SOT223-3L), confirmed electrical parameters (VOUT=1.2V, IOUT=1.5A, VDROPOUT=190mV), thermal protection threshold (170°C), and real-world transient response data for low-voltage microprocessor power design.
Technical Context
The AP7363-12E-13 integrates an internal 0.605V reference, current-limit circuitry, and thermal shutdown logic into a single-pass-element LDO architecture. Its internal compensation ensures stability with any capacitor type-including 10µF ceramic-eliminating ESR dependency.
Designed for fast load transients, it achieves <25µs turn-on/turn-off delay and maintains 90° phase margin under 1.5A load. The device uses a fixed-output configuration with no ADJ pin connection, simplifying layout while retaining full protection functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±2% - precisely targets FPGA I/O supply rails without external feedback components. |
| Max Output Current | 1.5A continuous - supports high-current digital loads like GPU memory interfaces and multi-core SoC I/O banks. |
| Dropout Voltage | 190mV at 1.5A - enables operation from 1.4V input (e.g., battery-backed 1.5V rail) while maintaining regulation. |
| Quiescent Current | 0.5mA typical - minimizes standby power loss in always-on subsystems such as USB-C PD controllers and sensor hubs. |
| Thermal Shutdown | 170°C junction threshold with 10°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
| Input Voltage Range | 2.2V to 5.5V - compatible with common intermediate rails (3.3V, 2.5V, 1.8V) and allows direct use after buck converter stages. |
| PSRR @ 1kHz | 61dB - suppresses switching noise from upstream DC-DC converters, reducing need for additional filtering. |
| Output Noise | 100µVrms (100Hz–100kHz) - meets low-noise requirements for analog peripherals and ADC reference supplies. |
Pinout & Package
SOT223-3L package with exposed thermal tab (pin 2 = GND, pin 1 = IN, pin 3 = OUT). The thermally enhanced leadframe supports up to 105.7°C/W junction-to-ambient resistance on standard 2oz FR-4 layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Main input voltage supply pin; requires ≥2.2V and must be decoupled with ≥2.2µF ceramic capacitor placed adjacent to pin. |
| 2 | GND | Ground reference and thermal path; connects to exposed tab for heat dissipation-must be soldered to ≥1cm² copper pour. |
| 3 | OUT | Regulated 1.2V output; stable with 10µF ceramic capacitor; drives load directly without external compensation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 190mV at 1.5A enables operation from marginal input rails (e.g., 1.4V battery decay) without dropout-induced system reset. |
| No ESR dependency | Internal compensation eliminates capacitor ESR constraints-supports polymer, tantalum, or ceramic outputs interchangeably. |
| Fast transient response | Load step recovery within 40µs (100mA ↔ 1.5A) prevents brownout during burst-mode processor activity. |
| Low-noise regulation | 100µVrms integrated noise avoids signal integrity degradation in mixed-signal SoCs and high-resolution ADC references. |
| Robust fault protection | Current limit (~3.7A peak) and thermal shutdown (170°C) operate independently to prevent latch-up or silicon failure. |
Applications
| ASIC Power Supplies in Routers | FPGA I/O Power Delivery |

IC Role / Device Role / Timing Role: Compact SOT223 LDO converting 5V input to 1.2V core supply with minimal board area and thermal overhead. Use Value: 0.5mA quiescent current extends standby time in remote-wakeup applications, while 105.7°C/W θJA enables passive cooling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1826-1202E/DB | 1.2V fixed, 1.5A, 250mV dropout, 80µA IQ, no thermal shutdown | Lacks thermal protection; suitable only for well-ventilated, low-power designs with strict IQ budget | Select only when thermal derating is guaranteed and 190mV dropout margin is unnecessary. |
| Torex XC6210B122MR-G | 1.2V fixed, 1A, 150mV dropout, 35µA IQ, 150°C thermal shutdown | Lower current rating and tighter thermal trip point reduce robustness under sustained 1.5A load | Use only for sub-1A applications where ultra-low IQ outweighs current capability and thermal safety margin. |
Compared with MCP1826-1202E/DB and XC6210B122MR-G, AP7363-12E-13 uniquely combines 1.5A delivery, 190mV dropout, full thermal shutdown, and 0.5mA IQ in SOT223-making it optimal for thermally constrained, high-reliability FPGA/ASIC I/O rails where protection and performance coexist.

FAQ
What is the maximum allowable input voltage for AP7363-12E-13?
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 if below 6.0V, especially under high ambient temperatures or heavy load conditions where power dissipation increases significantly.
Can AP7363-12E-13 be used with tantalum output capacitors?
Yes-AP7363-12E-13 is internally compensated and stable with any capacitor type, including tantalum, polymer, or ceramic, regardless of ESR value. Unlike traditional LDOs, it does not require minimum ESR for stability, eliminating capacitor selection constraints.
Does AP7363-12E-13 include enable or shutdown control?
No-the AP7363-12E-13 variant has no EN pin or shutdown function. It operates continuously when input voltage is applied. For applications requiring controlled start-up or standby mode, consider the adjustable AP7363-ADJ version with external enable circuitry or alternate parts like AP2204K-12.
How is thermal performance affected by PCB layout for SOT223 package?
Thermal resistance drops from 105.7°C/W (standard 2oz FR-4) to ≤65°C/W when the exposed tab is soldered to ≥2cm² copper area with ≥4 thermal vias. Insufficient copper or missing vias cause junction temperature to exceed 125°C at 1.2A load, triggering thermal shutdown.
