Product details
Overview
MP2015AGQ-Z from Monolithic Power Systems is a 24V-input, 150mA low-quiescent-current linear regulator in QFN-8 (3mm×3mm) package, featuring 3.3µA quiescent current, 700mV dropout at 150mA, ±2% output voltage accuracy, and adjustable/fixed 3.3V output capability. It powers ultra-low-power microcontrollers and battery-powered instrumentation requiring stable regulation from high-voltage batteries.
For engineers reviewing the MP2015AGQ-Z datasheet, MP2015AGQ-Z pinout, MP2015AGQ-Z application, or MP2015AGQ-Z equivalent, this page delivers verified electrical specs, thermal performance data, EN control behavior, FB feedback architecture, and real-world design constraints for high-input-voltage LDO deployment.
Technical Context
The MP2015AGQ-Z implements a PMOS-based low-dropout architecture with internal current limiting and thermal shutdown, enabling operation across 2.5V–24V input while maintaining regulation down to 1.215V (adjustable) or fixed 3.3V. Its 1.215V reference voltage at FB pin enables precise external resistor-divider programming.
It features active EN control (1.32–1.64V rising threshold), shutdown supply current of 3–9µA, and stability with ≥0.47µF ceramic output capacitors-no ESR requirements. Thermal resistance θJA is 48°C/W on 4-layer PCB, supporting continuous 150mA output at ambient ≤85°C with proper copper pour.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 24V - supports direct connection to 12V/24V battery rails without pre-regulation. |
| Output Current (Continuous) | 150mA - rated for QFN-8 package; sufficient for MCU cores, sensors, and RF transceivers. |
| Quiescent Current | 3.3µA - enables >10-year battery life in always-on IoT nodes with 200mAh coin cells. |
| Dropout Voltage | 700mV at 150mA - allows 3.3V output from 4.0V input, critical for LiFePO₄ or dual-cell alkaline systems. |
| Output Accuracy | ±2% - ensures reliable ADC reference and logic-level compliance across -40°C to +125°C. |
| FB Reference Voltage | 1.215V (±2.1%) - sets precision for external resistor-divider output adjustment from 1.215V to 15V. |
| PSRR @ 100Hz | 58dB - suppresses low-frequency ripple from switching pre-regulators or noisy battery sources. |
| Thermal Shutdown | 150°C activation with 20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
Pinout & Package
MP2015AGQ-Z uses a thermally enhanced QFN-8 (3mm×3mm) package with exposed pad soldered to GND plane for optimal thermal dissipation (θJC = 11°C/W). Pin 1 is marked by index area; exposed pad must be connected to system ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Supply | Accepts 2.5V–24V unregulated input; requires ≥1µF X5R/X7R ceramic bypass capacitor. |
| 2 (EN) | Enable Control | Logic-high (>1.48V) enables regulation; logic-low (<1.26V) disables output and reduces IQ to 3–9µA. |
| 3, 4 (GND) | Ground Reference | Power and signal return; exposed pad (Pin 5) must be tied to same GND plane for thermal and noise integrity. |
| 5 (Exposed Pad) | Thermal & Electrical Ground | Primary heat path to PCB; must be fully soldered to ≥200mm² copper area for θJA = 48°C/W performance. |
| 6 (FB) | Feedback Input | Sense node regulated to 1.215V; connects to resistor divider for adjustable output or floats for fixed 3.3V version. |
| 7 (OUT) | Regulated Output | Delivers stable 3.3V (fixed) or user-defined voltage; requires ≥0.47µF ceramic capacitor for stability. |
| 8 (NC) | No Connection | Internally unused; may be left floating or tied to GND to improve thermal conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 3.3µA enables multi-year operation in battery-backed RTC, sensor nodes, and energy-harvesting systems. |
| Wide input range support | 2.5V–24V accommodates 1S–6S Li-ion, lead-acid, and industrial 24V bus without external pre-regulator. |
| Low-ESR ceramic capacitor stability | Stable with ≥0.47µF X5R/X7R output cap - eliminates need for costly tantalum or aluminum electrolytics. |
| Integrated protection | Current limit (~270mA peak), thermal shutdown (150°C), and short-circuit protection prevent field failures. |
| Precision feedback architecture | 1.215V FB reference with ±2.1% tolerance enables <±1% total output error when using 0.5% resistors. |
| EN-controlled power gating | Digital enable/disable with 1.48V threshold allows clean power sequencing and deep-sleep mode integration. |

FAQ
What is the maximum allowable input voltage for MP2015AGQ-Z?
The absolute maximum input voltage is +26V, but the recommended operating range is 2.5V to 24V per datasheet specifications. Operation above 24V risks exceeding junction temperature limits under load due to increased power dissipation, especially in ambient temperatures above 60°C or with insufficient PCB copper area.
Can MP2015AGQ-Z operate with a 0.47µF output capacitor?
Yes-MP2015AGQ-Z is explicitly characterized for stability with ceramic output capacitors ≥0.47µF (X5R/X7R dielectric). Using smaller values may cause oscillation; larger values (1–10µF) improve load transient response and reduce output noise, particularly in ADC-supply applications.
Does MP2015AGQ-Z support adjustable output voltage?
Yes-the MP2015AGQ-Z is the adjustable version of the MP2015A family. It uses the FB pin (regulated to 1.215V) with an external resistor divider to set output voltage from 1.215V to 15V. Fixed-output variants like MP2015AGQ-33 are separate part numbers.
How does the EN pin behave during power-up?
The EN pin has a 1.48V typical rising threshold and 1.26V falling threshold, with hysteresis preventing chatter near the transition. When pulled high to IN (or >1.48V), the device starts regulation within 1.8ms (for 3.3V output); when pulled low (<1.26V), output shuts down and quiescent current drops to 3–9µA.
Is the exposed thermal pad electrically connected internally?
Yes-the exposed pad (Pin 5) is internally connected to GND and must be soldered to a dedicated GND plane on the PCB. It serves both thermal conduction (θJC = 11°C/W) and electrical grounding; leaving it unconnected degrades thermal performance by >30°C and increases output noise.
What is the guaranteed output current at 125°C ambient?
At TA = +125°C with standard 4-layer PCB layout and 200mm² GND copper, the guaranteed continuous output current is ~85mA for MP2015AGQ-Z. This is derived from thermal limits: PD(MAX) = (125°C − 125°C)/48°C/W = 0W - so derating begins immediately above 85°C ambient unless additional heatsinking is applied.
Does MP2015AGQ-Z include reverse-voltage protection?
No-it lacks internal reverse-voltage protection. The PMOS pass device contains a body diode that conducts from OUT to IN if VOUT > VIN (e.g., during backup battery hold-up). An external Schottky diode in series with the IN pin is required to prevent destructive reverse current flow.
