Product details
Overview
AP7363-15D-13 from Diodes Incorporated is a 1.5A fixed-output (1.5V) ultra-low dropout linear regulator in TO252-3L package, featuring 190mV dropout at full load, 0.5mA quiescent current, and integrated thermal shutdown/current limit protection. It delivers stable power to FPGA I/O rails, ASIC cores in routers and STBs, and post-regulation of 3.3V/5V SMPS outputs.
For engineers reviewing the AP7363-15D-13 datasheet, AP7363-15D-13 pinout, AP7363-15D-13 application, or AP7363-15D-13 equivalent, key selection criteria include dropout voltage at 1.5A, thermal resistance (θJA = 87.8°C/W), output noise (100µVrms), and compatibility with 10µF ceramic output capacitors without ESR constraints.
Technical Context
The AP7363-15D-13 uses an internal 0.605V bandgap reference and error amplifier to regulate fixed 1.5V output via trimmed resistor network; no external feedback components are required. Its internal compensation ensures stability with any capacitor type-including low-ESR ceramics-eliminating need for minimum ESR design constraints.
Thermal shutdown activates at +170°C junction temperature with 10°C hysteresis, while current limiting clamps peak output to ~3.7A. The device operates across -40°C to +85°C ambient and supports fast load transients due to optimized loop bandwidth and 90° phase margin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±2% tolerance; enables direct replacement of legacy 1.5V LDOs without resistor recalculations. |
| Dropout Voltage | 190mV at 1.5A; allows operation from 1.69V input, supporting single-cell LiFePO₄ or boosted 1.2V rail applications. |
| Quiescent Current | 0.5mA typical; maintains efficiency in always-on subsystems like router management controllers or sensor interface logic. |
| Output Noise | 100µVrms (100Hz–100kHz); meets noise-sensitive analog supply requirements for ADC references or RF bias rails. |
| Thermal Resistance | θJA = 87.8°C/W (TO252); enables 1.5A continuous operation up to +70°C ambient with standard 2oz copper pad. |
| Input Voltage Range | 2.2V to 5.5V; compatible with 3.3V and 5V system rails, simplifying BOM consolidation across multiple voltage domains. |
| Protection Features | Current limit (~3.7A) and thermal shutdown (+170°C); prevents catastrophic failure during short-circuit or PCB layout thermal bottlenecks. |
Pinout & Package
AP7363-15D-13 is housed in TO252-3L (DPAK) package with exposed thermal pad electrically connected to GND; recommended soldering to ≥100mm² copper area for thermal performance. Pin 1 = GND, Pin 2 = IN, Pin 3 = OUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground reference and thermal path | Primary return for internal circuitry; must be connected to system ground plane and thermal pad for safe 1.5A operation. |
| IN (Pin 2) | Input voltage supply | Accepts 2.2–5.5V; requires ≥2.2µF ceramic decoupling close to pin to suppress high-frequency noise from upstream SMPS. |
| OUT (Pin 3) | Regulated 1.5V output | Delivers up to 1.5A; stable with 10µF ceramic capacitor-no ESR tuning needed for transient response or stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 190mV @ 1.5A enables use in battery-powered systems where input voltage sags near output level. |
| Capacitor flexibility | Stable with any capacitor type (ceramic, tantalum, polymer); eliminates ESR matching effort and reduces BOM count. |
| Low-noise regulation | 100µVrms output noise supports precision analog circuits without external filtering or ferrite beads. |
| Robust protection | Integrated current limit and thermal shutdown prevent damage during board-level fault conditions like solder bridges or connector shorts. |
| Green packaging | Halogen- and antimony-free, fully RoHS-compliant TO252 package with matte tin plating for reliable solderability. |
Applications
| ASIC Power Supplies | FPGA I/O Rails |
|---|---|
|
Use Scenario: Powering ASIC cores in set-top boxes and network routers where clean, low-noise 1.5V is required for digital logic and SerDes interfaces. IC Role / Device Role / Timing Role: Primary post-regulator converting 3.3V SMPS output to stable 1.5V ASIC supply with minimal voltage ripple. Use Value: 100µVrms noise and fast transient response prevent timing jitter and bit errors in high-speed data paths. |
Use Scenario: Supplying configurable I/O banks on Xilinx Artix-7 or Intel Cyclone V FPGAs requiring tightly regulated 1.5V. IC Role / Device Role / Timing Role: Dedicated LDO per I/O bank to isolate switching noise from adjacent banks and ensure signal integrity. Use Value: 190mV dropout allows operation from 1.69V input, enabling efficient use of intermediate 1.8V rails without additional conversion stages. |
| SMPS Post-Regulation | DVD Player Audio Subsystem |
|
Use Scenario: Final-stage regulation after buck converter in consumer electronics to meet tight output tolerance and noise specs. IC Role / Device Role / Timing Role: Low-noise linear post-regulator improving PSRR beyond what the primary SMPS achieves alone. Use Value: 65dB PSRR at 120Hz suppresses low-frequency switching artifacts from upstream converters feeding audio DACs or sensors. |
Use Scenario: Providing 1.5V bias to audio codec ICs and op-amp buffers in DVD player mainboards. IC Role / Device Role / Timing Role: Clean analog supply rail decoupled from noisy digital domains using dedicated LDO with thermal robustness. Use Value: Thermal shutdown at +170°C protects against enclosure overheating during extended playback, ensuring field reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-1502E/MB | 150mA max output, SOT-23 package, 600mV dropout at 150mA | Only suitable for low-current logic rails-not viable for 1.5A FPGA I/O or ASIC core loads | Select only when load current ≤150mA and board space is constrained; not a functional replacement. |
| TLS850F1TAV50 | Automotive-grade AEC-Q100 qualified, 500mA output, integrated watchdog timer | Designed for automotive body control modules; lacks 1.5A capability and consumer-grade thermal specs | Choose only for automotive programs requiring PPAP documentation and extended temp support; over-specified for consumer STB/routers. |
Compared with MCP1703T-1502E/MB and TLS850F1TAV50, AP7363-15D-13 uniquely combines 1.5A output, 190mV dropout, and TO252 thermal performance-making it the only drop-in solution for high-current 1.5V FPGA/ASIC supplies in industrial and consumer equipment.

FAQ
Is AP7363-15D-13 pin-compatible with other AP7363 variants?
Yes-AP7363-15D-13 shares identical TO252-3L pinout (GND-IN-OUT) with all fixed-output AP7363-D variants (e.g., -10D-13, -18D-13). The ADJ version differs only internally; its TO252 variant does not exist per datasheet ordering table, so no pin conflict arises across fixed-output SKUs.
Can AP7363-15D-13 operate with only 2.2µF input capacitance?
Yes-the datasheet specifies a minimum 2.2µF ceramic capacitor on the IN pin. This value ensures stability and adequate transient suppression for most applications; larger values (e.g., 10µF) further improve load-step response but are not mandatory for basic functionality.
What is the maximum ambient temperature for continuous 1.5A operation?
At 1.5A and 2.2V input (max ΔV = 0.7V), power dissipation is 1.05W. With θJA = 87.8°C/W, junction rise is 92°C. Subtracting from TJMAX = 125°C gives max ambient of +33°C. For higher ambient, reduce load current or enhance PCB copper area per suggested pad layout.
Does AP7363-15D-13 require an external shutdown control signal?
No-it has no enable (EN) pin. The device operates continuously when input voltage is within 2.2–5.5V. Shutdown mode (25nA IQ) is not supported on fixed-output versions; only adjustable AP7363 variants include EN functionality per functional block diagram.
