Product details
Overview
AP7583AQ-MP-13 from Diodes Incorporated is an AEC-Q100 qualified automotive-grade 300mA ultra-low-dropout (ULDO) regulator with power-good (PG) output, 3V–42V input range, ±1.5% output voltage accuracy, and 3µA typical quiescent current. It delivers fixed 3.3V or 5V output (this variant is adjustable) and supports always-on MCU and CAN transceiver power in harsh battery environments.
For engineers reviewing the AP7583AQ-MP-13 datasheet, AP7583AQ-MP-13 pinout, AP7583AQ-MP-13 application, or AP7583AQ-MP-13 equivalent, key selection criteria include PG monitoring capability, thermal shutdown at +175°C, dropout of 320mV @300mA (5V), compatibility with low-ESR ceramic capacitors, and MSOP-8EP package suitability for space-constrained automotive PCBs.
Technical Context
The AP7583AQ integrates a precision 1.207V reference, error amplifier, current-limit circuit, thermal shutdown protection, and open-drain PG output with internal pull-up. Its feedback architecture uses an external resistor divider to set output from 1.2V to 5.0V, with FB pin leakage <20nA ensuring stable regulation under light loads.
It operates across -40°C to +125°C junction temperature, features UVLO activation at 2.4V (±0.3V hysteresis), and provides fast PG response (30µs rise-to-active, 3µs deglitch delay). The EN pin enables high-side control with VIH ≥1.7V and VIL ≤0.3V, supporting robust sequencing in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3V to 42V - supports direct connection to automotive battery rails including cold-crank (4.5V) and load-dump (40V) transients. |
| Output Current | 300mA max - sufficient for powering dual-core MCUs, CAN/LIN transceivers, and sensor signal chains simultaneously. |
| Dropout Voltage | 320mV @300mA (5V output) - enables stable 5V regulation even when VIN drops to 5.32V, critical during engine cranking. |
| Quiescent Current | 3µA typ - minimizes standby power loss in always-on domains such as body control modules and telematics. |
| Output Accuracy | ±1.5% - ensures reliable logic-level compliance for 3.3V/5V I/O interfaces without post-regulation trimming. |
| Power-Good Threshold | 90–94% of VOUT rising, 88–92% falling - provides precise supply monitoring for safe system boot and fault detection. |
| Thermal Shutdown | +175°C with +20°C hysteresis - protects against sustained overload or poor heatsinking in enclosed ECUs. |
Pinout & Package
AP7583AQ-MP-13 is housed in an MSOP-8EP (8-pin mini small outline package with exposed thermal pad), optimized for automotive thermal performance (θJA = 36.1°C/W) and PCB area efficiency. The exposed pad must be connected to GND via multiple vias for optimal heat dissipation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply pin - accepts 3V–42V; requires 10µF ceramic decoupling capacitor placed adjacent to pin. |
| 2 | EN | Active-high enable - drives regulator ON when ≥1.7V; tie to VIN if always-on operation is required. |
| 3 & 7 | NC | No-connect pins - recommended to connect to GND plane to enhance thermal conduction from EP. |
| 4 | PG | Open-drain power-good output - sinks current when VOUT falls below threshold; requires external pull-up for logic interface. |
| 5 & 6 | GND | Ground return paths - both pins must be low-impedance connections to minimize noise and improve PSRR. |
| 8 | VOUT | Regulated output - delivers up to 300mA; requires 10µF ceramic output capacitor with ESR <100mΩ for stability. |
| EP | Exposed Pad | Thermal interface - not electrically functional; must be soldered to large GND copper area with ≥4 thermal vias. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range (3V–42V) | Eliminates need for pre-regulator in 12V/24V automotive systems, reducing BOM count and board space. |
| Ultra-Low IQ (3µA) | Enables >10-year battery life in always-on vehicle modules powered by backup batteries or supercaps. |
| Integrated Power-Good (PG) | Provides deterministic system reset and supply sequencing without external comparators or discrete logic. |
| AEC-Q100 Qualified | Validated for Grade 1 (-40°C to +125°C) operation with PPAP documentation support for Tier 1 automotive programs. |
| Low-ESR Ceramic Cap Compatible | Supports compact, high-reliability 0603/0805 MLCCs instead of bulkier tantalum or aluminum electrolytics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7B8250QDGNRQ1 | Higher IQ (12µA), lower dropout (200mV @300mA), no PG output, same 3V–40V input. | Lacks integrated PG monitoring - requires external supervisor IC for sequencing or fault reporting. | Select when lowest possible dropout is prioritized over supply monitoring and ultra-low IQ is secondary. |
| NCP163AMX330TBG | Lower current (250mA), higher IQ (10µA), no PG, wider temp range (–55°C to +150°C), same AEC-Q100 Grade 1. | Not suitable for 300mA peak loads like dual-CAN or MCU+peripheral combinations. | Select only for cost-sensitive, lower-current nodes where PG functionality is handled elsewhere in the system. |
Compared with TPS7B8250QDGNRQ1 and NCP163AMX330TBG, AP7583AQ-MP-13 uniquely balances ultra-low IQ (3µA), integrated PG, and 300mA capability in a single MSOP-8EP footprint-making it optimal for space- and power-constrained automotive subsystems requiring autonomous supply validation.

FAQ
What is the function of the PG pin on AP7583AQ-MP-13?
The PG (power-good) pin is an open-drain output with internal pull-up that signals valid regulation: it enters high-impedance state when VOUT reaches ≥90% of nominal value and pulls low when VOUT drops below 88% or EN is deasserted. It requires an external pull-up resistor (typically 10kΩ) to interface with MCU GPIO or reset controllers.
Can AP7583AQ-MP-13 be used in adjustable-output configurations?
Yes - AP7583AQ-MP-13 is the adjustable version (no suffix indicating fixed voltage), using an external resistor divider between FB and GND to set output from 1.2V to 5.0V. The internal reference is 1.207V (±24mV), and R2 must be ≤80kΩ to maintain reference stability per datasheet guidance.
What thermal design considerations apply to the MSOP-8EP package?
The MSOP-8EP exposes a thermal pad (EP) that must be soldered to a minimum 25mm² GND copper area with ≥4 thermal vias (0.3mm diameter) to achieve the rated θJA of 36.1°C/W. Without proper thermal land, junction temperature may exceed +125°C under 300mA load at 42V input, triggering thermal shutdown.
Is AP7583AQ-MP-13 compatible with ceramic output capacitors smaller than 10µF?
Yes - the device is stable with output capacitance from 4.7µF to 100µF, provided ESR remains below 100mΩ. A 4.7µF X7R 0805 ceramic capacitor is acceptable for space-constrained layouts, though 10µF is recommended for optimal transient response and PSRR above 10kHz.
