Product details
Overview
AP7583AQ-50MP-13 from Diodes Incorporated is an AEC-Q100 qualified 5.0V fixed-output ultra-low-dropout (ULDO) regulator delivering 300mA output current with 320mV dropout at full load, 3μA quiescent current, ±1.5% output voltage 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-50MP-13 datasheet, AP7583AQ-50MP-13 pinout, AP7583AQ-50MP-13 application, or AP7583AQ-50MP-13 equivalent, key selection criteria include wide 3V–42V input range, thermal shutdown behavior, PG threshold hysteresis (±2%), EN logic compatibility (VIH ≥ 1.7V), and MSOP-8EP package thermal resistance (θJA = 36.1°C/W).
Technical Context
The AP7583AQ-50MP-13 integrates a precision 1.207V reference, error amplifier, current-limit circuit, thermal shutdown comparator, and open-drain PG output with internal pull-up. Its feedback loop uses a fixed resistor network for 5.0V regulation, eliminating external components in fixed-voltage configurations.
Operation relies on high-side PMOS pass transistor architecture enabling low dropout and ultra-low IQ. The PG function monitors VOUT against 90–94% VPGR and 88–92% VPGF thresholds, with 30µs response time and 3µs deglitching to prevent false triggering during transient events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1.5% - ensures stable MCU/CAN supply within automotive voltage tolerance bands |
| Input Voltage Range | 3.0V to 42V - supports cold-crank (4.5V) and load-dump (40V) conditions per ISO 16750-2 |
| Dropout Voltage | 320mV typ @ 300mA - enables regulation down to 5.32V input, critical for battery-powered systems |
| Quiescent Current | 3μA typ - sustains >10-year battery life in always-on vehicle modules |
| Power-Good Threshold | VPGR = 90–94% of VOUT, VPGF = 88–92% - provides clean sequencing signal with 2% hysteresis |
| Thermal Shutdown | Triggers at +175°C, resets at +155°C - protects against sustained overload in confined enclosures |
| Current Limit | 310–690mA - clamps fault current while maintaining safe junction temperature |
Pinout & Package
AP7583AQ-50MP-13 is housed in an MSOP-8EP (8-pin mini small outline package with exposed thermal pad), optimized for automotive PCB space constraints and thermal performance (θJA = 36.1°C/W). The exposed pad must be connected to GND via multiple vias for effective heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input supply connection | Accepts 3–42V unregulated input; requires 10µF ceramic decoupling placed adjacent to pin |
| EN (Pin 2) | Enable control input | Active-high logic interface; VIH ≥ 1.7V ensures compatibility with 3.3V/5V microcontrollers |
| NC (Pin 3) | No-connect terminal | Internally unconnected; recommended to tie to GND for thermal copper area enhancement |
| PG (Pin 4) | Open-drain power-good indicator | Sinks 5mA when VOUT < VPGF; high-Z when VOUT ≥ VPGR - used for supply sequencing and fault reporting |
| GND (Pins 5 & 7) | Ground reference and return path | Dual ground pins reduce impedance and improve PSRR; both must connect to low-impedance system ground plane |
| VOUT (Pin 8) | Regulated output | Delivers 5.0V ±1.5% at up to 300mA; requires 10µF ceramic output capacitor for stability |
| EP (Exposed Pad) | Thermal conduction path | Not electrically functional; must be soldered to large GND copper area with ≥4 thermal vias for θJA compliance |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (3V–42V) | Enables single-regulator support across 12V and 24V automotive architectures without redesign |
| Ultra-low 3μA quiescent current | Reduces standby power loss to <15μW at 5V, extending battery life in always-on telematics modules |
| Integrated power-good (PG) output | Eliminates need for external supervisor IC in multi-rail systems requiring precise supply sequencing |
| AEC-Q100 Grade 1 qualification | Validated for operation from −40°C to +125°C ambient, meeting automotive reliability requirements |
| Low ESR capacitor compatibility | Stable with 4.7µF–100µF ceramic output capacitors, reducing BOM count and board area |

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-50MP-13 | Lacks PG output; 2.5μA IQ vs. 3μA; identical pinout and electrical specs otherwise | Used where supply monitoring is handled externally or unnecessary | Select when PG functionality adds no value and lowest possible IQ is prioritized |
| TLE42754G | Higher IQ (15μA); 40V max input; no adjustable version; different pinout (TO-252) | Targeted at cost-sensitive legacy TCU designs with less stringent quiescent current demands | Choose only if existing TO-252 footprint and higher IQ are acceptable trade-offs |
Compared with AP7583Q-50MP-13, the AP7583AQ-50MP-13 adds PG monitoring at +0.5μA IQ penalty, while TLE42754G offers lower cost but sacrifices 2× thermal resistance and lacks modern low-IQ capability-making AP7583AQ-50MP-13 optimal for new AEC-Q100 designs requiring sequencing assurance.

FAQ
What is the minimum input voltage required for regulation at 5.0V output?
The AP7583AQ-50MP-13 requires VIN ≥ VOUT + VDROP to maintain regulation. With typical dropout of 320mV at 300mA, minimum input is 5.32V. At light loads, dropout drops further-enabling operation down to 5.05V input while maintaining ±1.5% accuracy per datasheet test conditions.
Can the PG pin drive an LED directly for status indication?
No-the PG pin is an open-drain output rated for 5mA sink current. Driving an LED requires a series current-limiting resistor and external pull-up to a compatible voltage rail (e.g., 5V or 3.3V). Direct connection to VCC without current limiting risks exceeding the PG pin's absolute maximum rating of 7V.
Is the MSOP-8EP package RoHS and halogen-free compliant?
Yes-AP7583AQ-50MP-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, with full compliance documentation available at diodes.com/quality/lead-free.
Does the device require a minimum load for stability?
No-AP7583AQ-50MP-13 remains stable and fully regulated from zero load to 300mA. The datasheet explicitly states "no minimum load is required," verified across −40°C to +125°C with 10µF ceramic output capacitance, making it ideal for intermittent-duty automotive sensors and sleep-mode MCU rails.
