Product details
Overview
AP7583Q-50FDZW-7 from Diodes Incorporated is an automotive-grade 5.0V fixed-output ultra-low-dropout (ULDO) linear regulator delivering 300mA output current with 320mV dropout at full load, 2.5µA quiescent current, and ±1.5% output voltage accuracy - designed for always-on power domains in CAN transceivers and microcontrollers.
For engineers reviewing the AP7583Q-50FDZW-7 datasheet, AP7583Q-50FDZW-7 pinout, AP7583Q-50FDZW-7 application, or AP7583Q-50FDZW-7 equivalent, this part supports AEC-Q100 qualification, operates across 3V–42V input range, features thermal shutdown and current-limit protection, and is packaged in W-DFN2020-6 (SWP) Type A1 for high-density automotive PCBs.
Technical Context
The AP7583Q-50FDZW-7 integrates a precision 1.2V reference, error amplifier, and PMOS pass transistor to achieve low dropout and high line/load regulation. Its internal current-limit circuit triggers at 310–690mA and thermal shutdown activates at +175°C with +20°C hysteresis.
It operates without minimum load and remains stable with 4.7µF–100µF ceramic output capacitors. The EN pin accepts logic-high signals ≥1.7V to enable regulation, while UVLO engages below 2.1V with 0.2V hysteresis to prevent erratic startup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1.5% - ensures reliable MCU/CAN transceiver biasing under battery voltage fluctuations. |
| Max Output Current | 300mA - sufficient for dual-core automotive MCUs and CAN/LIN transceivers in body control modules. |
| Dropout Voltage | 320mV typ @ 300mA - enables regulation down to VIN = 5.32V, critical during cold-crank (6V) conditions. |
| Quiescent Current | 2.5µA typ - minimizes standby power loss in always-on domains like alarm controllers and gateway ECUs. |
| Input Voltage Range | 3.0V to 42V - covers automotive battery transients including load dump (40V) and cold-crank (3V). |
| Thermal Shutdown | +175°C activation with +20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| PSRR | 70dB @ 100Hz - suppresses alternator ripple and switching noise before sensitive analog or digital loads. |
Pinout & Package
AP7583Q-50FDZW-7 uses the W-DFN2020-6 (SWP) Type A1 package: 2.0mm × 2.0mm footprint, 0.65mm pitch, exposed thermal pad (EP) on bottom. Recommended PCB layout uses ≥20mm² copper area connected to GND under EP for θJA = 80.4°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VIN | Input supply connection | Accepts 3V–42V; requires 10µF ceramic decoupling capacitor placed within 2mm of pin. |
| 2 EN | Enable control input | Active-high logic interface; must exceed 1.7V to enable output; tied to VIN if always-on operation required. |
| 3 GND | Power ground reference | Primary return path for load current and feedback network; connects directly to thermal pad via multiple vias. |
| 4 VOUT | Regulated output terminal | Delivers stable 5.0V ±1.5%; supports 4.7µF–100µF ceramic output capacitors for transient stability. |
| 5 NC(Q) | No-connect (AP7583Q variant) | Internally unconnected; recommended to tie to GND for enhanced thermal conduction and EMI reduction. |
| 6 FB/NC | Feedback input / no-connect | NC in fixed-output version; unused pin - leave floating or connect to GND per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2.5µA typ enables >10-year battery life in vehicle intrusion detection systems with wake-on-CAN. |
| Wide input voltage range | 3V–42V accommodates 12V and 24V automotive architectures, including ISO 7637-2 pulse 5a (40V load dump). |
| Low dropout voltage | 320mV @ 300mA allows uninterrupted operation during engine cranking (VIN ≥5.32V for 5V output). |
| AEC-Q100 qualified | Grade 1 (−40°C to +125°C TJ) qualification confirms reliability for under-hood and cabin applications. |
| Integrated protection | Current limit (310–690mA), thermal shutdown (+175°C), and UVLO (2.1–2.7V) reduce need for external fault management. |
Applications
| Automotive Body Control Module (BCM) | EV Battery Management System (BMS) Sensor Interface |
|---|---|
Use Scenario: Powering LIN transceivers, door lock actuators, and ambient light sensors in centralized BCMs. IC Role / Device Role / Timing Role: Primary 5V rail regulator supplying always-on logic and communication peripherals.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7583AQ-50FDZW-7 | Includes open-drain PG output; 3µA IQ vs. 2.5µA; identical electrical specs otherwise. | Required where power sequencing or supply monitoring (e.g., MCU reset assertion) is needed. | Select when system-level fault reporting or multi-rail sequencing is mandatory. |
| TLE42754G | 5V fixed, 400mA, 450mV dropout @ 400mA, 15µA IQ, TO-252 package only. | Larger thermal footprint; higher IQ limits use in ultra-low-power always-on nodes. | Choose for legacy designs requiring pin-compatible replacement with higher current margin but less stringent IQ requirements. |
Compared with AP7583AQ-50FDZW-7, the AP7583Q-50FDZW-7 trades PG functionality for 0.5µA lower quiescent current - critical for multi-year battery-backed modules. Versus TLE42754G, it offers 6x lower IQ and 30% smaller footprint but 100mA lower current capacity.

FAQ
What is the maximum allowable input voltage for continuous operation?
The AP7583Q-50FDZW-7 supports continuous operation up to 42V input, verified per Recommended Operating Conditions. Absolute maximum rating is 45V, but sustained operation above 42V risks reliability degradation and violates AEC-Q100 stress limits. Input transients up to 40V (per ISO 7637-2 Pulse 5a) are fully supported with proper input capacitance.
Can the AP7583Q-50FDZW-7 be used without an external output capacitor?
No - a minimum 4.7µF ceramic output capacitor is required for stability, as confirmed in the Electrical Characteristics table and Application Information section. Omitting COUT causes oscillation and output voltage collapse. The device is optimized for 10µF (recommended), with stable operation guaranteed across 4.7µF–100µF.
Is the exposed thermal pad (EP) electrically connected internally?
No - the EP is not internally connected to any die node. Per Pin Descriptions and Package Outline documentation, it serves solely as a thermal conduction path. It must be connected to PCB GND plane via ≥4 thermal vias (0.3mm diameter) to achieve specified θJA = 80.4°C/W and prevent thermal shutdown under 300mA load.
Does the AP7583Q-50FDZW-7 require a minimum load current to maintain regulation?
No - the AP7583Q-50FDZW-7 remains stable and regulated at zero load, as explicitly stated in the "No Load Stability" subsection. Unlike older LDOs, it does not require a minimum output current (e.g., 1mA) to sustain feedback loop stability or output accuracy.
