Product details
Overview
AP7583AQ-33MP-13 from Diodes Incorporated is an AEC-Q100 qualified 3.3V fixed-output ultra-low-dropout (ULDO) regulator delivering 300mA with 320mV dropout at full load, 3µA quiescent current, ±1.5% output accuracy, and integrated power-good (PG) monitoring-designed for always-on automotive subsystems including CAN transceivers and body control modules.
For engineers reviewing the AP7583AQ-33MP-13 datasheet, AP7583AQ-33MP-13 pinout, AP7583AQ-33MP-13 application, or AP7583AQ-33MP-13 equivalent, key selection criteria include input voltage range (3–42V), thermal shutdown threshold (+175°C), PG timing response (30µs rise-to-active), and MSOP-8EP package compatibility with automotive PCB layout constraints.
Technical Context
The AP7583AQ-33MP-13 integrates a precision 1.207V internal reference, error amplifier, and gate driver in a single-stage LDO architecture optimized for wide-input automotive battery rails. Its feedback loop uses a fixed resistor network for 3.3V output regulation and includes dedicated PG comparator with 90–94% VOUT rising threshold and 88–92% falling hysteresis.
It implements overcurrent protection via foldback current limiting (310–690mA trip range), thermal shutdown with +20°C hysteresis, and undervoltage lockout (UVLO) activation at 2.4V nominal VIN. The EN pin supports active-high logic control with 1.7V VIH and 0.3V VIL thresholds, enabling precise power sequencing in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±1.5% - ensures stable MCU core supply under battery voltage fluctuations. |
| Max Input Voltage | 42V - supports 24V commercial/12V passenger vehicle battery systems with load dump tolerance. |
| Dropout Voltage | 320mV @300mA - enables regulation down to VIN = 3.62V, critical for cold-crank operation. |
| Quiescent Current | 3µA typ - minimizes standby power loss in always-on domains like CAN wake-up circuits. |
| Power-Good Threshold | VPGR = 90–94% of VOUT - provides accurate supply monitoring without external comparators. |
| Thermal Shutdown | +175°C with +20°C hysteresis - prevents latch-up during transient overload or poor heatsinking. |
| PSRR | 70dB @100Hz - suppresses alternator ripple and switching noise on downstream analog/sensor rails. |
Pinout & Package
AP7583AQ-33MP-13 is housed in an MSOP-8EP (8-pin mini small outline package with exposed thermal pad), optimized for high-power-density automotive PCBs. The exposed pad must be connected to GND via multiple vias for thermal dissipation (θJA = 36.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Main input supply | Accepts 3–42V unregulated battery rail; requires 10µF ceramic decoupling adjacent to pin. |
| 2 (EN) | Enable control | Active-high logic input; ties to VIN for permanent ON or interfaces with microcontroller GPIO for sequencing. |
| 3 & 7 (NC) | No-connect terminals | Internally unconnected; recommended to tie to GND plane for thermal conduction and EMI reduction. |
| 4 (PG) | Power-good open-drain output | Signals valid VOUT with 30µs response; requires external pull-up for system reset or supervisor IC interfacing. |
| 5 & 6 (GND) | Ground return paths | Dual GND pins reduce ground impedance and improve PSRR; both must connect to low-impedance GND plane. |
| 8 (VOUT) | Regulated output | Delivers 3.3V @300mA; requires 10µF ceramic output capacitor with ESR <100mΩ for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (3–42V) | Supports 12V/24V automotive platforms and accommodates ISO 7637-2 pulse 5a (load dump up to 40V). |
| Ultra-low IQ (3µA) | Enables >10-year battery life in telematics modules powered by backup coin cells or supercaps. |
| Integrated PG monitor | Eliminates need for external supervisor IC in CAN/LIN node power sequencing and fault reporting. |
| AEC-Q100 Grade 1 | Qualified for -40°C to +125°C ambient operation, PPAP-capable, manufactured in IATF16949 facilities. |
| Low-ESR capacitor compatible | Stable with 4.7–100µF ceramic outputs, reducing BOM count and board space vs. tantalum alternatives. |
Applications
| Automotive Body Control Module (BCM) | EV Battery Management System (BMS) Sensor Interface |
|---|---|
Use Scenario: Powering microcontrollers, LIN transceivers, and door-lock actuators in centralized BCMs. IC Role / Device Role / Timing Role: Primary 3.3V supply for safety-critical MCU domain with PG signaling for system-level power validation. Use Value: Enables fail-safe power sequencing and diagnostic logging via PG assertion before MCU boot. | Use Scenario: Regulating sensor bias rails (e.g., temperature, voltage sense ICs) in high-voltage EV battery packs. IC Role / Device Role / Timing Role: Isolated low-noise 3.3V source with UVLO and thermal shutdown for analog front-end conditioning. Use Value: Maintains sensor accuracy across wide battery voltage swings (8–45V) while preventing thermal runaway. |
| Automotive Head Unit (HU) Display Subsystem | Transmission Control Unit (TCU) Communication Interface |
Use Scenario: Supplying display controller, touch IC, and backlight drivers in infotainment head units. IC Role / Device Role / Timing Role: Secondary LDO after main DC-DC converter; PG output synchronizes display enable with stable VDD. Use Value: Prevents display artifacts or ghost touches caused by premature initialization during power ramp-up. | Use Scenario: Powering CAN FD transceivers and isolated communication gateways in TCU modules. IC Role / Device Role / Timing Role: Dedicated 3.3V rail with fast PG response (<30µs) for CAN bus arbitration readiness. Use Value: Guarantees CAN transceiver operational status before firmware initiates bus communication. |
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-33MP-13 | No PG output; 2.5µA IQ vs. 3µA; identical pinout and electrical specs otherwise. | Used where system-level power monitoring is handled externally or not required. | Select when PG functionality adds unnecessary cost or complexity to the BOM. |
| TLD5098ELXUMA1 | Higher IQ (15µA); 40V max VIN; integrated watchdog timer; SO-8 package. | Targets lighting control ICs requiring built-in diagnostics, not general-purpose MCU/CAN supply. | Choose only if watchdog supervision and LED driver integration are mandatory design requirements. |
Compared with AP7583Q-33MP-13, the AP7583AQ-33MP-13 adds PG monitoring at minimal IQ penalty (0.5µA increase), while TLD5098ELXUMA1 trades off ultra-low IQ for integrated functional safety features irrelevant to basic power regulation tasks.

FAQ
What is the minimum input voltage required for AP7583AQ-33MP-13 to regulate 3.3V output at 300mA?
The minimum input voltage is determined by dropout: VIN(min) = VOUT + V DROP = 3.3V + 0.45V = 3.75V (max spec). At typical 320mV dropout, 3.62V suffices. Below 3.0V, UVLO disables regulation regardless of load.
Can AP7583AQ-33MP-13 operate with a 2.2µF output capacitor?
No. The datasheet specifies a stable output capacitance range of 4.7µF to 100µF. Using 2.2µF violates stability criteria and may cause oscillation or poor transient response, especially under load steps from 1mA to 300mA.
How does the PG pin behave during thermal shutdown?
During thermal shutdown, the PG pin is actively pulled low by an internal MOSFET, indicating loss of valid output. It remains low until VOUT recovers above the 88–92% falling threshold after junction temperature drops below +155°C.
Is the MSOP-8EP package RoHS and halogen-free compliant?
Yes. AP7583AQ-33MP-13 meets EU Directive 2015/863/EU (RoHS 3), contains <900ppm bromine and chlorine combined, <1000ppm antimony, and is certified "Green" per Diodes Incorporated's definition.
