Product details
Overview
AP7583AQ-33FDZW-7 from Diodes Incorporated is an AEC-Q100 qualified 3.3V fixed-output ultra-low-dropout linear regulator with power-good (PG) monitoring, designed for automotive battery-powered systems. It delivers 300mA output current with 320mV dropout at full load, 3µA quiescent current, ±1.5% output voltage accuracy, and operates across 3V–42V input range-enabling direct connection to 12V/24V vehicle batteries. It powers always-on subsystems including CAN transceivers and microcontrollers in body control modules.
For engineers reviewing the AP7583AQ-33FDZW-7 datasheet, AP7583AQ-33FDZW-7 pinout, AP7583AQ-33FDZW-7 application, or AP7583AQ-33FDZW-7 equivalent, key selection criteria include PG threshold timing (30µs response), thermal shutdown at +175°C, compatibility with low-ESR ceramic capacitors (4.7–100µF), and W-DFN2020-6 package thermal resistance (θJA = 80.4°C/W).
Technical Context
The AP7583AQ-33FDZW-7 integrates a precision 1.207V reference, error amplifier, current-limit circuit, thermal shutdown comparator, and open-drain PG output with internal pull-up. Its feedback loop uses a fixed resistor divider for 3.3V regulation, eliminating external components while maintaining ±1.5% accuracy over -40°C to +125°C junction temperature.
Control logic includes active-high EN with 1.7V VIH threshold, UVLO activation at 2.4V (±0.3V hysteresis), and PG assertion when VOUT reaches 90% of nominal (3.3V → VPGR = 2.97V). The device sustains stable operation without minimum load and supports fast transient response (<80µs recovery under 1–300mA load steps).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±1.5% - ensures reliable MCU/CAN transceiver supply within automotive voltage tolerance bands. |
| Max Output Current | 300mA - sufficient for dual-core MCUs and CAN/LIN transceivers in body electronics. |
| Dropout Voltage | 320mV @300mA - enables regulation down to VIN = 3.62V, supporting cold-crank (6.5V) and start-stop scenarios. |
| Quiescent Current | 3µA typ - minimizes standby power loss in always-on domains like alarm controllers and gateway ECUs. |
| Power-Good Threshold | VPGR = 90% × VOUT (2.97V), VPGF = 88% × VOUT (2.90V) - provides precise supply monitoring for sequencing and fault detection. |
| Thermal Shutdown | +175°C with +20°C hysteresis - protects against sustained overload in confined under-hood environments. |
| Input Voltage Range | 3V to 42V - covers full automotive battery range including load dump (40V) and cold-crank dips. |
Pinout & Package
AP7583AQ-33FDZW-7 is housed in a thermally enhanced W-DFN2020-6 (SWP) Type A1 package with 0.65mm pitch and exposed thermal pad. PCB layout requires direct connection of the EP to GND plane via multiple vias for θJA = 80.4°C/W performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply rail | Accepts 3–42V; must be decoupled with ≥10µF ceramic capacitor placed adjacent to pin 1. |
| EN | Enable control input | Active-high logic (VIH ≥1.7V); tie to VIN if always-on operation required. |
| GND | Ground reference | Common return for input/output paths and thermal pad; connects to internal die substrate. |
| VOUT | Regulated output | Delivers stable 3.3V; requires ≥4.7µF low-ESR ceramic capacitor for stability. |
| NC / PG | Power-good open-drain output | Drives low when VOUT < 2.90V or EN = low; pulls high-impedance above 2.97V for system monitoring. |
| FB/NC | Feedback / Not connected | No connection required for fixed 3.3V version; left floating per datasheet recommendation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (3–42V) | Eliminates need for pre-regulator in 12V/24V automotive systems, reducing BOM count and board space. |
| Ultra-low IQ (3µA) | Enables >10-year battery life in always-on telematics modules powered by backup coin cells or supercaps. |
| Integrated PG output | Replaces discrete voltage supervisor ICs, simplifying power sequencing in multi-rail ECUs like TCUs. |
| AEC-Q100 Grade 1 | Qualified for operation from -40°C to +125°C ambient, meeting stringent automotive reliability requirements. |
| Thermal shutdown + hysteresis | Prevents latch-up during intermittent overload; automatic recovery at +155°C avoids manual reset intervention. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7B8233QPWPRQ1 | Higher IQ (1.8µA), lower dropout (210mV @300mA), but no PG output and narrower 1.5–40V input range. | Lacks integrated power monitoring; requires external supervisor for sequencing-critical gateways. | Select when lowest possible IQ dominates over PG functionality and input range margin is acceptable. |
| NCP163AMX330TBG | Lower max current (250mA), higher dropout (400mV @250mA), no AEC-Q100 qualification, and no PG pin. | Not suitable for safety-critical or high-reliability automotive domains requiring PPAP documentation. | Consider only for cost-sensitive non-automotive industrial applications where AEC-Q100 is not mandated. |
Compared with TPS7B8233QPWPRQ1 and NCP163AMX330TBG, the AP7583AQ-33FDZW-7 uniquely combines AEC-Q100 qualification, integrated PG, 42V input capability, and 3µA IQ in a 2mm×2mm DFN-making it optimal for compact, safety-aware automotive subsystems requiring autonomous supply validation.

FAQ
What is the purpose of the PG pin on AP7583AQ-33FDZW-7?
The PG (power-good) pin is an open-drain output that signals valid regulation status. It enters high-impedance state when VOUT exceeds 90% of 3.3V (2.97V) and pulls low when VOUT drops below 88% (2.90V) or EN is deasserted. This enables precise supply monitoring and sequencing in multi-rail automotive ECUs without external supervisors.
Can AP7583AQ-33FDZW-7 operate with ceramic output capacitors smaller than 10µF?
Yes-the device remains stable with output capacitance as low as 4.7µF, provided the capacitor's ESR is ≤10mΩ. The recommended 10µF value ensures margin across temperature and aging; lower values may reduce transient response robustness in high-dI/dt applications like camera ISPs.
How does the thermal shutdown behavior affect system reliability?
Thermal shutdown activates at +175°C junction temperature and releases at +155°C (20°C hysteresis), preventing permanent damage during overload or poor heatsinking. In continuous cycling mode, it limits average power dissipation-ensuring long-term reliability in sealed enclosures like headlamp control units without forced airflow.
Is the EN pin compatible with 3.3V logic microcontrollers?
Yes-EN accepts 1.7V minimum high-level input (VIH), making it directly drivable by standard 3.3V GPIOs. No level-shifting is needed. When unused, EN should be tied to VIN to maintain continuous operation, as specified in the datasheet's ON/OFF Input Operation section.
