Product details
Overview
AP7583Q-MP-13 from Diodes Incorporated is an AEC-Q100 qualified 300mA ultra-low-quiescent-current LDO regulator with 3V–42V input range, 3.3V fixed output, 2.5µA typical IQ, and 320mV dropout at 300mA - designed for always-on automotive subsystems including MCU core rails and CAN transceiver power supplies.
For engineers reviewing the AP7583Q-MP-13 datasheet, AP7583Q-MP-13 pinout, AP7583Q-MP-13 application, or AP7583Q-MP-13 equivalent, this part supports critical low-power, high-reliability vehicle electronics where wide VIN tolerance, thermal robustness, and precise voltage regulation under light-load conditions are mandatory.
Technical Context
The AP7583Q integrates a precision 1.207V reference, error amplifier, current-limit circuit, thermal shutdown protection, and chip-enable logic in a single monolithic IC. Its architecture delivers ±1.5% output accuracy across -40°C to +125°C and maintains stability with ceramic capacitors as low as 4.7µF.
It operates without minimum load requirement and features EN-controlled startup with 0.8ms turn-on delay and 200µs output ramp time. The device implements internal current limiting (310–690mA), thermal cycling protection (175°C trip, 20°C hysteresis), and UVLO (2.4V nominal enable threshold).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3V to 42V - supports direct connection to automotive battery rail with cold-crank and load-dump immunity. |
| Output Voltage | Fixed 3.3V ±1.5% - meets MCU I/O and CAN transceiver VCC requirements without external feedback resistors. |
| Max Output Current | 300mA - sufficient for dual-core microcontrollers and integrated CAN/LIN transceivers in body control modules. |
| Dropout Voltage | 320mV @300mA - enables stable 3.3V output even when VIN drops to 3.62V, critical during engine cranking. |
| Quiescent Current | 2.5µA typ - minimizes standby power loss in always-on domains such as alarm systems and remote keyless entry receivers. |
| Thermal Shutdown | 175°C trip temperature - protects against sustained overloads in enclosed ECUs with limited airflow. |
| PSRR | 70dB @100Hz - suppresses alternator ripple and switching noise from adjacent DC/DC converters. |
Pinout & Package
AP7583Q-MP-13 uses the MSOP-8EP package (3.0mm × 4.9mm × 1.1mm) with exposed thermal pad. PCB layout requires large copper area connected to GND under the EP for optimal thermal dissipation (θJA = 36.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VIN | Input supply connection | Accepts 3–42V unregulated automotive battery; must be decoupled with ≥10µF ceramic capacitor placed adjacent to pin. |
| 2 EN | Enable control input | Active-high logic interface (VIH ≥1.7V); ties to VIN for permanent ON operation; supports controlled power sequencing. |
| 3,7 NC | No-connect terminal | Internally unconnected; recommended to tie to GND for enhanced thermal conduction via PCB copper fill. |
| 4,5 GND | Ground reference | Dual ground pins reduce impedance path for return current and improve PSRR performance. |
| 6 VOUT | Regulated output | Delivers stable 3.3V ±1.5%; requires ≥4.7µF ceramic output capacitor; supports up to 300mA continuous load. |
| 8 EP | Exposed thermal pad | Not electrically functional; must be soldered to GND plane for thermal management - not used as primary GND electrode. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2.5µA typ enables >10-year battery life in always-on vehicle modules powered by 12V lead-acid batteries. |
| Wide input voltage range | 3V–42V operation accommodates automotive transients including ISO 7637-2 pulse 5a (load dump up to 40V) without external clamping. |
| Low dropout voltage | 320mV @300mA ensures regulation during cold-crank events where battery dips below 6V while maintaining 3.3V system rail. |
| Integrated thermal shutdown | 175°C trip with 20°C hysteresis prevents latch-up during short-circuit faults and allows safe auto-recovery in thermally constrained enclosures. |
| AEC-Q100 qualification | Qualified to Grade 1 (-40°C to +125°C) with PPAP capability and IATF16949 manufacturing - suitable for safety-critical body and powertrain ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7583AQ-MP-13 | Includes open-drain PG output (90% VOUT threshold); 3µA IQ vs. 2.5µA | Required where power sequencing or supply monitoring is needed (e.g., multi-rail ECUs) | Select AQ version if system-level fault detection or coordinated power-up/down timing is required. |
| TLE42744G V33 | Higher IQ (15µA), lower max current (250mA), same AEC-Q100 Grade 1 rating | Suitable for simpler, lower-current nodes but lacks ultra-low-IQ advantage for long-term standby | Choose TLE42744G only when legacy Infineon footprint compatibility is mandatory and IQ budget allows. |
Compared with AP7583AQ-MP-13, the Q version trades PG functionality for 0.5µA lower IQ - critical for multi-month battery-off endurance. Versus TLE42744G, AP7583Q delivers 20% higher current capacity and one-sixth the quiescent current, making it superior for next-gen low-power automotive nodes.

FAQ
What is the minimum input voltage required for AP7583Q-MP-13 to regulate 3.3V output at full 300mA load?
The dropout voltage is 320mV typ at 300mA, so minimum VIN = 3.3V + 0.32V = 3.62V. This ensures regulation during cold-crank events where battery voltage may dip below 6V. Absolute minimum VIN per datasheet is 3.0V, but output will drop out below 3.62V under full load.
Can AP7583Q-MP-13 operate without an external output capacitor?
No - a minimum 4.7µF ceramic output capacitor is required for stability. The device is optimized for 10µF, and operation outside 4.7–100µF may cause oscillation or poor transient response. No minimum load current is needed, but capacitor is mandatory.
Is the EN pin 5V-tolerant when used with a 12V automotive microcontroller GPIO?
No - VIH is specified as 1.7V to VIN, and maximum EN voltage is VIN. Direct connection to 12V GPIO would exceed absolute maximum ratings. Use a level-shifting resistor divider or buffer to limit EN voltage to ≤VIN (max 42V) and ensure VIH ≥1.7V.
Does AP7583Q-MP-13 require thermal derating above +85°C ambient?
Yes - θJA is 36.1°C/W on JEDEC-standard board. At TA = +85°C, maximum allowable power dissipation before reaching TJ = +125°C is PD = (125–85)/36.1 ≈ 1.11W. For VIN = 14V and VOUT = 3.3V, max sustainable IOUT = 1.11W / (14–3.3) ≈ 104mA above +85°C.
