Product details
Overview
AP7583Q-50MP-13 from Diodes Incorporated is a 5.0V fixed-output, 300mA ultra-low-dropout (ULDO) linear regulator 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 3V–42V input environments.
For engineers reviewing the AP7583Q-50MP-13 datasheet, AP7583Q-50MP-13 pinout, AP7583Q-50MP-13 application, or AP7583Q-50MP-13 equivalent, key selection criteria include 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-50MP-13 integrates a precision 1.2V bandgap reference, error amplifier, and PMOS pass transistor to achieve high line/load regulation (<±20mV) and 70dB PSRR at 100Hz. Its internal current-limit circuit triggers at 310–690mA and thermal shutdown activates at +175°C with +20°C hysteresis.
Unlike standard LDOs, it supports no-load stability and operates across -40°C to +125°C junction temperature with UVLO activation at 2.1–2.7V and 0.2V hysteresis. The EN pin enables active-high control with VIH ≥ 1.7V and VIL ≤ 0.3V, ensuring robust interface with automotive logic levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1.5% - ensures stable MCU core/peripheral rail without external feedback resistors. |
| Max Output Current | 300mA - sufficient for dual-core automotive MCUs and integrated CAN/LIN transceivers. |
| Dropout Voltage | 320mV typ @ 300mA - maintains regulation down to VIN = 5.32V, critical during cold-crank (6V) conditions. |
| Quiescent Current | 2.5µA typ - enables >10-year battery standby life in always-on telematics modules. |
| Input Voltage Range | 3V to 42V - covers full automotive battery range including load dump (40V) and cold-crank (3V). |
| Thermal Shutdown | +175°C activation - protects against sustained overloads in enclosed ECU housings. |
| PSRR | 70dB @ 100Hz - suppresses alternator ripple and switching noise before sensitive analog/RF circuits. |
Pinout & Package
AP7583Q-50MP-13 uses the MSOP-8EP package (3.0mm × 4.9mm × 1.1mm) with exposed thermal pad (EP) connected to GND for optimal heat dissipation (θJA = 36.1°C/W). PCB layout requires ≥200mm² copper area under EP tied to GND plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Input supply rail | Accepts 3–42V unregulated battery input; requires 10µF ceramic decoupling placed <2mm from pin. |
| 2 (EN) | Enable control input | Active-high logic interface; must exceed 1.7V to enable output; ties to VIN if always-on operation required. |
| 3,7 (NC) | No-connect terminal | Internally unconnected; recommended to tie to GND for enhanced thermal conduction via PCB copper. |
| 4,5 (GND) | Ground reference | Dual GND pins reduce impedance path for return current; connect directly to solid ground plane. |
| 6 (VOUT) | Regulated output | Delivers stable 5.0V ±1.5%; supports 4.7–100µF ceramic output capacitors for transient response. |
| 8 (EP) | Thermal pad | Not electrically functional; must be soldered to ≥200mm² GND copper area for thermal reliability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualified | Validated for -40°C to +125°C operation in engine bay ECUs and body controllers. |
| Ultra-low IQ (2.5µA) | Enables >10-year battery drain budget for parking-mode ADAS sensors and telematics. |
| Wide VIN range (3–42V) | Eliminates need for pre-regulator in 12V/24V systems facing load dump and cold-crank stress. |
| Low dropout (320mV @ 300mA) | Maintains 5V output during 6V cold-crank events, preventing MCU brownout resets. |
| Thermal shutdown + hysteresis | Auto-recovery at +155°C prevents latch-up during intermittent overload in compact enclosures. |

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-50MP-13 | Includes open-drain PG output (90–94% VOUT threshold); IQ = 3µA vs. 2.5µA | Required where power sequencing or supply monitoring is needed (e.g., multi-rail ECUs) | Select when PG signal is mandatory for system-level fault detection or startup coordination. |
| TLE42754G | Higher IQ (15µA); 40V max VIN; no adjustable version; PG output included | Broadly used in legacy Infineon automotive platforms; less suitable for ultra-low-power always-on nodes | Choose for drop-in replacement in existing TLE42754 designs requiring AEC-Q100 compliance and similar thermal specs. |
Compared with AP7583AQ-50MP-13, the Q variant trades PG functionality for 20% lower quiescent current-critical for battery-sensitive modules. Versus TLE42754G, AP7583Q offers 6× lower IQ and wider VIN range but lacks integrated watchdog or reset functions.

FAQ
What is the minimum input voltage required for regulation at 5.0V output?
The AP7583Q-50MP-13 maintains regulation when VIN ≥ VOUT + VDROP. With a typical dropout of 320mV at 300mA, the minimum input is 5.32V. Under light loads, dropout drops further-enabling operation down to 5.05V while maintaining ±1.5% accuracy per datasheet specifications.
Can this regulator operate without an output capacitor?
No. The AP7583Q-50MP-13 requires a minimum 4.7µF ceramic output capacitor for stability across its operating range. The datasheet specifies stable operation between 4.7µF and 100µF; omitting the capacitor causes oscillation and potential device failure due to phase margin loss in the control loop.
Is the EN pin 5V-tolerant when driven by a 5V microcontroller GPIO?
Yes. The EN pin accepts VIH up to VIN (max 42V) and has absolute maximum rating of 45V. When VIN = 14V, VIH threshold is 1.7V minimum-fully compatible with 3.3V or 5V logic. No level-shifting is required, simplifying interface with common automotive MCUs.
How does thermal performance differ between MSOP-8EP and TO252-4 packages?
The MSOP-8EP (θJA = 36.1°C/W) provides better thermal resistance than W-DFN2020-6 (80.4°C/W) but higher than TO252-4 (27.2°C/W). For 300mA at 14V input, MSOP-8EP dissipates 2.7W and rises ~97°C above ambient-requiring ≥200mm² thermal pad copper. TO252-4 reduces junction rise to ~73°C, enabling higher ambient operation in sealed enclosures.
