Product details
Overview
AP7583Q-33MP-13 from Diodes Incorporated is a 3.3V fixed-output, 300mA ultra-low-dropout (ULDO) linear regulator designed for automotive battery-powered systems. It delivers ±1.5% output voltage accuracy, 320mV dropout at 300mA, and 2.5µA quiescent current-enabling always-on operation for microcontrollers and CAN transceivers in engine control units and body electronics.
For engineers reviewing the AP7583Q-33MP-13 datasheet, AP7583Q-33MP-13 pinout, AP7583Q-33MP-13 application, or AP7583Q-33MP-13 equivalent, key selection criteria include its AEC-Q100 qualification, MSOP-8EP thermal performance (θJA = 36.1°C/W), PG absence (Q variant), and compatibility with low-ESR ceramic capacitors down to 4.7µF.
Technical Context
The AP7583Q-33MP-13 integrates a precision 1.2V bandgap reference, error amplifier, and PMOS pass transistor to achieve stable regulation across 3V–42V input range. 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 requirement and supports fast enable turn-on delay (0.8ms typ) and output ramp-up (200µs typ). The device uses an external resistor divider only in adjustable versions; this 3.3V fixed variant eliminates FB pin dependency while retaining EN-controlled sequencing capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±1.5% - ensures reliable MCU core/logic supply under automotive voltage transients. |
| Max Input Voltage | 42V - withstands load-dump events up to ISO 7637-2 Pulse 5a without external protection. |
| Dropout Voltage | 320mV @300mA - enables regulation down to VIN = 3.62V, critical for cold-crank operation. |
| Quiescent Current | 2.5µA typ - minimizes standby power loss in always-on domains like CAN wake-up receivers. |
| Thermal Shutdown | +175°C activation - protects against sustained overload or poor PCB heatsinking in confined enclosures. |
| PSRR | 70dB @100Hz - suppresses alternator ripple and switching noise before sensitive analog/RF subsystems. |
| Line Regulation | ±10mV - maintains tight output stability during battery voltage swings from 9V to 16V. |
Pinout & Package
AP7583Q-33MP-13 is housed in an MSOP-8EP package with exposed thermal pad (EP), optimized for automotive thermal cycling reliability. The 3mm × 4.9mm footprint supports high-density layout while enabling efficient heat transfer via soldered EP connection to internal ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VIN | Input voltage supply | Accepts 3V–42V DC; requires local 10µF ceramic decoupling within 3mm of pin for stability. |
| 2 EN | Enable control input | Active-high logic interface (VIH ≥1.7V); ties to VIN for permanent ON; drives <0.5µA shutdown current. |
| 3,7 NC | No-connect terminal | Internally unconnected; recommended to tie to GND for enhanced thermal conduction from EP. |
| 4,5 GND | Ground reference | Dual ground pins reduce impedance path for return current and improve PSRR performance. |
| 6 VOUT | Regulated output | 3.3V fixed output; supports 4.7µF–100µF ceramic output capacitors with ESR <100mΩ. |
| 8 EP | Exposed thermal pad | Must be soldered to large PCB copper area connected to GND; not electrically functional as GND node alone. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range | 3V–42V operation covers full automotive battery range including cold-crank (≥6V) and load-dump (≤42V). |
| Ultra-low IQ | 2.5µA typical quiescent current enables >10-year battery life in always-on telematics modules. |
| Low dropout | 320mV dropout at full 300mA load allows use in 5V rail generation from 5.5V auxiliary supplies. |
| AEC-Q100 qualified | Qualified to Grade 1 (-40°C to +125°C) with PPAP support and IATF16949 manufacturing traceability. |
| Short-circuit protection | Current-limit foldback prevents thermal runaway during sustained output shorts in wiring harness faults. |

IC Role / Device Role / Timing Role: Always-on LDO maintaining CAN bus bias during ignition-off monitoring; enables wake-on-CAN functionality. Use Value: 320mV dropout sustains 3.3V output even when battery dips to 3.62V during cranking; 70dB PSRR rejects alternator noise. |
| Body Control Module (BCM) | Infotainment System MCU |
|
Use Scenario: Regulates power for LIN slave nodes, door lock actuators, and ambient light sensors in distributed body electronics architecture. IC Role / Device Role / Timing Role: Local point-of-load regulator eliminating long trace IR drops; enables independent on/off control per subsystem via EN pin. Use Value: Dual GND pins minimize ground bounce in noisy motor-drive environments; thermal shutdown prevents latch-up during short-circuit faults. |
Use Scenario: Provides 3.3V supply to application processor I/O banks and display interface logic in automotive head units. IC Role / Device Role / Timing Role: Secondary LDO filtering ripple from primary DC/DC converter; supports fast enable/disable for display power sequencing.

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-33MP-13 | Includes open-drain PG output; 3µA IQ (vs. 2.5µA); identical electrical specs otherwise. | Required where supply monitoring or power sequencing with downstream ICs is needed. | Select AQ version if system-level fault detection or multi-rail startup coordination is required. |
| TLE4275G V33 | Higher IQ (15µA); 40V max VIN; no EN pin; TO-252-4 package only. | Lacks enable control and thermal shutdown hysteresis; suited for simpler, non-sequenced loads. | Choose TLE4275G only when EN functionality and ultra-low IQ are not required, and TO252-4 thermal profile is acceptable. |
Compared with AP7583AQ-33MP-13, the Q variant trades PG functionality for lower quiescent current-ideal for cost-sensitive, always-on nodes without sequencing needs. Versus TLE4275G, AP7583Q offers superior IQ, EN control, and MSOP-8EP thermal density for space-constrained modules.

FAQ
What is the maximum allowable input voltage for AP7583Q-33MP-13?
The absolute maximum input voltage is 45V, but the recommended operating range is 3.0V to 42V per datasheet specifications. Operation above 42V risks exceeding safe operating area limits during load-dump transients unless external clamping is used. The 42V upper limit ensures reliable performance under ISO 7637-2 Pulse 5a conditions without derating.
Does AP7583Q-33MP-13 require an external feedback resistor network?
No. The AP7583Q-33MP-13 is a fixed 3.3V output variant and does not use the FB pin; it is internally configured with precision resistors. The FB/NC pin (Pin 6 in MSOP-8EP) is not connected internally and should be left floating or tied to GND for mechanical stability-no external divider is needed or supported.
How does the thermal pad (EP) function in the MSOP-8EP package?
The exposed pad (EP) serves solely as a thermal conduction path-not an electrical node. It must be soldered to a large PCB copper area connected to GND for optimal heat dissipation. Diodes specifies θJA = 36.1°C/W under JEDEC Std. 51 conditions; omitting EP soldering increases junction temperature by >25°C at full load, risking thermal shutdown.
Can AP7583Q-33MP-13 be used in non-automotive applications?
Yes-its 3V–42V input range, 2.5µA IQ, and ±1.5% accuracy make it suitable for industrial IoT sensors and 24V PLC peripherals. However, AEC-Q100 qualification and IATF16949 manufacturing ensure automotive-grade reliability; non-automotive users benefit from proven robustness but pay a slight premium over commercial-grade equivalents.
