Product details
Overview
MPQ2019GN-5-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified 40V input, 5V fixed-output linear regulator delivering up to 300mA with 10µA quiescent current, 480mV dropout at 300mA, ±2% output accuracy over temperature, and integrated power-good signaling-designed for automotive body control modules requiring stable low-power bias under cold-crank conditions.
For engineers reviewing the MPQ2019GN-5-AEC1-Z datasheet, MPQ2019GN-5-AEC1-Z pinout, MPQ2019GN-5-AEC1-Z application, or MPQ2019GN-5-AEC1-Z equivalent, key selection criteria include its 3V–40V input range, programmable PG delay (5–15ms), thermal shutdown at 165°C, SOIC-8 EP package with exposed pad, and AEC-Q100 qualification for automotive ambient operation up to +125°C junction.
Technical Context
The MPQ2019GN-5-AEC1-Z implements a PMOS pass transistor architecture enabling low-dropout operation across its full 3V–40V input range while maintaining ultra-low quiescent current. Its internal feedback reference is trimmed to 1.25V, and the fixed 5V output version integrates precision resistor dividers (R1_IN = 3MΩ, R2_IN = 1MΩ) yielding ±2% output accuracy from –40°C to +125°C ambient.
It features dual-stage protection: cycle-by-cycle current limiting (600–1350mA peak) combined with thermal shutdown (165°C trip, 30°C hysteresis) and open-drain power-good monitoring with user-programmable delay via external capacitor on PGDL. The EN pin supports logic-level enable/disable with 0.3V/1.8V thresholds and <0.5µA input current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3V to 40V - supports automotive battery transients including cold-crank (4.5V) and load-dump (40V). |
| Output Voltage | Fixed 5.0V ±2% - factory-trimmed for precision biasing of microcontrollers and CAN transceivers. |
| Max Output Current | 300mA continuous - sufficient for MCU cores, sensors, and interface ICs in distributed ECUs. |
| Quiescent Current | 10µA typical - enables >10-year battery standby in always-on automotive modules. |
| Dropout Voltage | 480mV at 300mA - ensures regulation down to VIN = 5.48V, critical during engine cranking. |
| Power-Good Delay | Programmable 5–15ms via PGDL capacitor - synchronizes system reset timing with rail stabilization. |
| Thermal Shutdown | 165°C with 30°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
MPQ2019GN-5-AEC1-Z is housed in a SOIC-8 EP (exposed pad) package compliant with JEDEC MS-012 BA. The exposed thermal pad must be soldered to a dedicated ground plane for thermal performance (θJA = 50°C/W, θJC = 10°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT | Regulated 5V output | Delivers stable 5V; requires only ≥0.47µF ceramic capacitor for stability. |
| 2 NC | No connection | Internally unconnected; must remain floating per design. |
| 3 GND | Ground reference & thermal path | Connects to PCB ground plane; exposed pad must be soldered to same plane for thermal dissipation. |
| 4 IN | High-voltage input supply | Accepts 3–40V; requires 1µF–10µF X5R/X7R ceramic input capacitor. |
| 5 EN | Enable control input | Logic high (>1.8V) enables regulator; logic low (<0.3V) shuts down to <1µA quiescent current. |
| 6 PG | Open-drain power-good indicator | Pulls high when VOUT reaches 92–96% of 5V; sinks 1mA at ≤0.4V when faulted. |
| 7 PGDL | Power-good delay programming | Charging current 3–9µA sets delay time (t = C × 1.7V / I); 47nF yields ~10ms typical. |
| 8 FB | Feedback reference node | Internally connected to 5V divider; unused in fixed-output version but must remain unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive operation from –40°C to +125°C ambient, supporting under-hood ECU deployment. |
| Programmable power-good delay | Enables precise sequencing control by setting PG assertion delay from 5ms to 15ms using external capacitor. |
| Stable with low-ESR ceramic capacitors | Guaranteed stability with ≥0.47µF X5R/X7R output cap - eliminates need for costly tantalum or polymer types. |
| Integrated short-circuit and thermal protection | Combines foldback current limiting and 165°C thermal shutdown with 30°C hysteresis for robust fault recovery. |
| Ultra-low 10µA quiescent current | Minimizes battery drain in always-on systems such as telematics and alarm controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output automotive LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7B6750QDDARQ1 | Higher IQ (25µA), lower max current (250mA), no PGDL programmability, same 5V fixed output and AEC-Q100 Grade 1. | Lacks programmable PG delay; suitable where fixed 200ms PG delay suffices and lower current is acceptable. | Select if board space is constrained (SOT-223) and PG delay flexibility is not required. |
| NCP160AMX500AATBG | Lower IQ (500nA), lower current (150mA), no PG or thermal shutdown, AEC-Q100 Grade 2 (–40°C to +105°C). | Not rated for under-hood ambient; lacks fault protection and power-good signaling. | Only for non-critical, low-power interior modules where cost is primary and protection is handled externally. |

FAQ
What is the maximum allowable input voltage for MPQ2019GN-5-AEC1-Z?
The absolute maximum input voltage is +42V, but the recommended operating range is 3V to 40V. Operation above 40V risks exceeding safe power dissipation limits and may trigger thermal shutdown even at light loads due to increased junction temperature.
Can MPQ2019GN-5-AEC1-Z be used without connecting the PGDL pin?
Yes - PGDL can be left floating if programmable power-good delay is not required. In that case, the PG signal asserts immediately upon output reaching regulation threshold (92–96% of 5V), with no intentional delay.
Is the exposed pad on the SOIC-8 EP package electrically connected?
Yes - the exposed pad is internally connected to GND and must be soldered to a PCB ground plane. It serves as both the primary thermal path and electrical ground return, contributing significantly to θJA reduction and long-term reliability.
Does MPQ2019GN-5-AEC1-Z require an external feedback resistor network?
No - the "-5" suffix denotes the fixed 5V output version with internal resistor dividers (3MΩ/1MΩ). The FB pin is internally connected and must remain unconnected; adding external resistors will disrupt regulation and accuracy.
How does the EN pin behave during automotive stop-start cycles?
The EN pin has 0.3V low and 1.8V high thresholds with <0.5µA leakage. During stop-start, if EN is tied to VIN, the regulator automatically re-enables as battery voltage recovers above 3V - ensuring seamless restart without external sequencing logic.
What is the minimum output capacitor required for stability?
A single 0.47µF X5R or X7R ceramic capacitor is sufficient for stability. Larger values (e.g., 22µF) improve load transient response and reduce output noise, especially in sensitive analog or ADC-supply applications.
Is MPQ2019GN-5-AEC1-Z compatible with lead-free reflow profiles?
Yes - it is RoHS-compliant, halogen-free, and qualified for standard lead-free reflow (J-STD-020, peak 260°C). The SOIC-8 EP package supports both manual and automated assembly with verified thermal reliability.
