Product details
Overview
AP7583AQ-50FDZW-7 from Diodes Incorporated is an AEC-Q100 qualified 5.0V fixed-output ultra-low-dropout (ULDO) regulator for automotive battery-powered systems, delivering 300mA output current with 320mV dropout at full load, ±1.5% output accuracy, and 3μA quiescent current - enabling always-on operation for CAN transceivers and microcontrollers in EV/HEV battery management modules.
For engineers reviewing the AP7583AQ-50FDZW-7 datasheet, AP7583AQ-50FDZW-7 pinout, AP7583AQ-50FDZW-7 application, or AP7583AQ-50FDZW-7 equivalent, key selection criteria include its 3V–42V input range, power-good (PG) monitoring capability, thermal shutdown at +175°C, and W-DFN2020-6 (SWP) package compatibility with high-density automotive PCB layouts.
Technical Context
The AP7583AQ integrates a precision 1.207V reference, error amplifier, and gate driver to regulate output voltage across wide line/load variations while maintaining ±100 ppm/°C temperature coefficient. Its PG circuit uses internal resistive divider thresholds (VPGR = 90–94% VOUT, VPGF = 88–92% VOUT) to assert open-drain status within 30µs of valid output establishment.
Current-limit protection activates at 310–690mA, and thermal shutdown engages at +175°C with +20°C hysteresis. The device supports adjustable outputs via FB pin (1.2V reference), but AP7583AQ-50FDZW-7 is factory-configured for 5.0V fixed output with integrated PG functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1.5% - ensures stable MCU/CAN supply under battery voltage fluctuations from 3V to 42V. |
| Max Output Current | 300mA - sufficient for powering dual-core automotive MCUs and CAN/LIN transceivers simultaneously. |
| Dropout Voltage | 320mV typ @ 300mA - enables regulation down to VIN = 5.32V, critical for cold-crank automotive conditions. |
| Quiescent Current | 3μA typ - minimizes standby power loss in always-on domains like body control modules. |
| Power-Good Threshold | VPGR = 90–94% VOUT, VPGF = 88–92% VOUT - provides precise supply monitoring for sequencing and fault detection. |
| Thermal Shutdown | +175°C with +20°C hysteresis - protects against sustained overload in enclosed ECU enclosures. |
| ESD Rating | HBM ±2000V, CDM ±1500V - meets automotive robustness requirements for assembly and field operation. |
Pinout & Package
AP7583AQ-50FDZW-7 uses the W-DFN2020-6 (SWP) Type A1 package: 2.0mm × 2.0mm footprint, 0.65mm pitch, exposed thermal pad (EP) for enhanced heat dissipation. PCB layout requires direct connection of EP to GND plane via multiple vias for optimal θJA = 80.4°C/W performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply rail | Accepts 3V–42V automotive battery input; requires 10µF ceramic decoupling capacitor placed adjacent to pin. |
| EN | Enable control | Active-high logic input (VIH ≥ 1.7V); ties to VIN for permanent enable or interfaces with system controller for power sequencing. |
| GND | Ground reference | Dual GND pins (pins 3 & 4) reduce ground impedance and improve PSRR; must connect to low-impedance PCB ground plane. |
| VOUT | Regulated output | Delivers 5.0V ±1.5% to load; requires 4.7µF–100µF ceramic output capacitor for stability across -40°C to +125°C. |
| PG | Power-good indicator | Open-drain output with internal pull-up; sinks 5mA when VOUT drops below 92% of nominal, enabling fault flagging and supply sequencing. |
| FB/NC | Feedback / No-connect | NC on fixed-output variant; left unconnected per datasheet - not used for voltage setting or compensation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range | 3V–42V operation supports 12V/24V/48V automotive architectures including start-stop and cold-crank scenarios. |
| Ultra-low IQ | 3μA quiescent current enables >10-year battery life in always-on telematics modules without compromising regulation. |
| Integrated PG monitor | Factory-trimmed PG thresholds eliminate external comparator circuitry and reduce BOM count in multi-rail ECUs. |
| AEC-Q100 qualification | Qualified to Grade 1 (-40°C to +125°C), PPAP-capable, and manufactured in IATF16949-certified facilities for automotive production use. |
| Thermal & current protection | Auto-recovering thermal shutdown (+175°C) and foldback current limit prevent latch-up during short-circuit or overtemperature events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7583Q-50FDZW-7 | No PG output; 2.5μA IQ vs. 3μA; identical pinout and electrical specs otherwise. | Suitable where supply monitoring is handled externally or unnecessary. | Select when PG function adds no value and lowest possible IQ is prioritized. |
| TLE42754G | Higher IQ (15μA), 400mA output, no adjustable option, different pinout (TO-252-5). | Used in legacy power distribution units with higher current demand and less stringent IQ requirements. | Choose only if existing PCB layout accommodates TO-252-5 and 15μA IQ is acceptable. |
Compared with AP7583Q-50FDZW-7, the AP7583AQ-50FDZW-7 adds essential PG monitoring for safety-critical sequencing without increasing footprint or thermal resistance, while the TLE42754G trades IQ and integration for higher current and legacy package compatibility - making AP7583AQ-50FDZW-7 optimal for new compact automotive designs requiring diagnostic capability.

FAQ
What is the minimum input voltage required for AP7583AQ-50FDZW-7 to maintain regulated 5.0V output at 300mA?
The minimum input voltage is calculated as VOUT + VDROP = 5.0V + 0.32V = 5.32V under typical conditions. At worst-case dropout (700mV), VIN must be ≥5.7V. This ensures stable operation during automotive cold-crank events where battery voltage may dip to 6V, provided layout minimizes trace resistance.
Can AP7583AQ-50FDZW-7 be used with ceramic output capacitors smaller than 10µF?
Yes - the device is stable with output capacitance from 4.7µF to 100µF. A 4.7µF X7R ceramic capacitor meets minimum stability requirements and reduces board area, though 10µF is recommended for optimal transient response in high-dI/dt applications like MCU core switching.
How does the power-good (PG) pin behave during EN assertion and VIN ramp-up?
PG remains low until VOUT reaches 90% of 5.0V (4.5V), then transitions to high-impedance after 30µs. During EN deassertion or VIN undervoltage (below 2.1V), PG actively pulls low within 3µs. This behavior enables precise power sequencing and fault detection without external timing components.
Is thermal derating required when operating AP7583AQ-50FDZW-7 at 300mA in a 70°C ambient environment?
Yes - with θJA = 80.4°C/W, power dissipation at 300mA and VIN = 14V is PD = (14V − 5V) × 0.3A = 2.7W, raising junction temperature by 217°C above ambient. Since TJ(max) = 150°C, this exceeds rating; design must reduce load current, lower VIN, or enhance heatsinking via EP vias and copper area to maintain TJ ≤ 125°C.
