Product details
Overview
AP7583AQ-33D4-13 from Diodes Incorporated is a 3.3V fixed-output, 300mA ultra-low-dropout linear regulator with power-good (PG) monitoring, AEC-Q100 qualified for automotive use, operating across 3V–42V input and delivering ±1.5% output accuracy with 320mV dropout at full load - deployed in body control modules and CAN transceiver power rails.
For engineers reviewing the AP7583AQ-33D4-13 datasheet, AP7583AQ-33D4-13 pinout, AP7583AQ-33D4-13 application, or AP7583AQ-33D4-13 equivalent, key selection criteria include PG threshold timing (30µs response), thermal shutdown hysteresis (+20°C), 3µA quiescent current, and TO252-4 package thermal resistance (θJA = 27.2°C/W).
Technical Context
The AP7583AQ-33D4-13 integrates a precision 1.207V internal reference, error amplifier, and gate driver to regulate output voltage with ±1.5% accuracy over -40°C to +125°C junction temperature. Its PG function uses an open-drain output with internal pull-up and 90–94% VFB rising threshold to signal valid regulation.
It implements current-limit protection (310–690mA trip), thermal shutdown at +175°C with +20°C hysteresis, and supports ceramic output capacitors from 4.7µF to 100µF. Input voltage ramp rate must stay below 200µs/V to ensure stable EN-controlled startup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±1.5% - ensures MCU/CAN transceiver supply meets ASIL-B voltage tolerance requirements. |
| Max Input Voltage | 42V - supports 24V automotive battery systems with load-dump margin. |
| Dropout Voltage | 320mV @300mA - enables stable 3.3V output even when VIN drops to 3.62V. |
| Quiescent Current | 3µA typ - sustains always-on operation in vehicle sleep modes without excessive battery drain. |
| Power-Good Response | 30µs PG active delay - provides fast system-level supply sequencing feedback for microcontrollers. |
| Thermal Resistance | θJA = 27.2°C/W (TO252-4) - allows >1.2W continuous dissipation at 25°C ambient before thermal shutdown. |
| Current Limit | 310–690mA - protects against short-circuit faults while permitting transient 300mA loads. |
Pinout & Package
AP7583AQ-33D4-13 is housed in TO252-4 (Type C) package with exposed thermal pad, optimized for high-power automotive PCB layouts requiring low θJA (27.2°C/W) and robust thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Input voltage supply | Accepts 3V–42V unregulated automotive rail; requires 10µF ceramic decoupling close to pin. |
| 2 (EN) | Enable control input | Active-high logic (VIH ≥1.7V); ties to VIN if always-on operation required. |
| 4 (PG) | Power-good open-drain output | Signals VOUT ≥90% of nominal via external pull-up; sinks 5mA max when asserted low. |
| 3 & 5 (GND) | Ground return paths | Dual GND pins reduce ground impedance and improve PSRR; connect directly to large copper pour. |
| 5 (VOUT) | Regulated output | Delivers 3.3V ±1.5%; stable with 4.7–100µF ceramic output capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (3V–42V) | Supports cold-crank (3V) and load-dump (42V) conditions without external protection circuitry. |
| Ultra-low IQ (3µA) | Enables <10µA system standby current when paired with low-IQ MCU and CAN transceiver. |
| PG output with 30µs response | Allows precise power sequencing in multi-rail ECUs - e.g., enabling MCU before CAN PHY. |
| AEC-Q100 Grade 1 qualification | Validated for -40°C to +125°C operation with PPAP documentation and IATF16949 manufacturing control. |
| Thermal shutdown with +20°C hysteresis | Prevents thermal runaway during sustained overload; auto-recovery avoids latch-up failures. |
Applications
| Body Control Module (BCM) | Transmission Control Unit (TCU) |
|---|---|
Use Scenario: Powering 3.3V microcontroller, LIN transceiver, and sensor interface ICs in door module ECU. IC Role / Device Role / Timing Role: Primary 3.3V LDO with PG monitoring for safe MCU boot and fault reporting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73333PQDBVRQ1 | 300mA, 3.3V, 4.5µA IQ, no PG, SOT-23-5 package (θJA = 216°C/W) | Lacks PG monitoring; unsuitable for supply sequencing or fault reporting. | Select only if PG is unnecessary and thermal budget permits higher junction temperature rise. |
| TPS7B8333QDCYRQ1 | 300mA, 3.3V, 2.7µA IQ, integrated PG with 100ms deglitch, 6-pin WSON | Slower PG response (100ms vs. 30µs); higher cost; smaller thermal pad (θJA = 100°C/W). | Choose when extended PG filtering is preferred over speed, and space-constrained layout favors WSON. |
Compared with TLV73333PQDBVRQ1 and TPS7B8333QDCYRQ1, the AP7583AQ-33D4-13 uniquely balances ultra-fast PG response, TO252-4 thermal performance, and AEC-Q100-compliant 3µA IQ - making it optimal for thermally demanding, safety-critical automotive subsystems requiring deterministic power sequencing.

FAQ
What is the minimum input voltage required for AP7583AQ-33D4-13 to maintain regulation?
The AP7583AQ-33D4-13 requires VIN ≥ VOUT + VDROP to sustain regulation. With 3.3V output and typical dropout of 320mV at 300mA, minimum VIN is 3.62V. Absolute minimum specified operating VIN is 3.0V, but regulation is not guaranteed below 3.62V under full load.
How does the PG pin behave during thermal shutdown?
During thermal shutdown, the AP7583AQ-33D4-13 disables the output and forces the PG pin low via its internal MOSFET, regardless of VOUT level. PG remains low until both thermal recovery occurs (TJ ≤ +155°C) and VOUT rises above the 90% VPGR threshold.
Can AP7583AQ-33D4-13 operate without an external output capacitor?
No. The device requires a minimum 4.7µF ceramic output capacitor for stability across its operating range. Omitting COUT causes oscillation and loss of regulation. Diodes recommends 10µF X7R/X5R ceramic placed within 3mm of VOUT and GND pins.
Is the EN pin 5V-tolerant when driven from a 5V microcontroller GPIO?
Yes. The EN pin accepts VIH up to VIN (max 42V), so a 5V logic signal fully satisfies the VIH ≥1.7V requirement. No level-shifting is needed. However, ensure the driving source can sink ≤0.5µA shutdown current when EN is pulled low.
