Monolithic Power Systems Inc. MP2015AGG-Z

Overview

MP2015AGG-Z from Monolithic Power Systems is a 24V-input, 150mA low-quiescent-current linear regulator in QFN-6 (2mm×2mm) package, featuring 2.5V–24V input range, 3.3µA quiescent current, and 700mV dropout at 150mA. It delivers ±2% output voltage accuracy and supports adjustable output (1.215V–15V) or fixed 3.3V variants-ideal for ultra-low-power microcontrollers in battery-powered industrial sensors.

For engineers reviewing the MP2015AGG-Z datasheet, MP2015AGG-Z pinout, MP2015AGG-Z application, or MP2015AGG-Z equivalent, this page provides verified pin functions, thermal shutdown behavior, EN control logic, FB feedback architecture, and real-world load regulation performance under 100µA–150mA conditions.

Technical Context

The MP2015AGG-Z uses a PMOS pass transistor with internal current limiting and thermal shutdown circuitry that activates at 150°C with 20°C hysteresis. Its feedback loop references a precision 1.215V bandgap voltage at the FB pin, enabling stable output regulation across –40°C to +125°C junction temperature.

It operates without external compensation, requiring only ≥0.47µF ceramic output capacitance for stability. The EN pin enables logic-controlled startup with 1.32V–1.64V rising threshold and <0.1µA input current, while the exposed thermal pad must be soldered to GND for θJA = 80°C/W operation.

Key Specifications

Pinout & Package

MP2015AGG-Z is housed in a thermally enhanced QFN-6 (2mm × 2mm) package with an exposed thermal pad on the bottom side, which must be soldered to a PCB ground plane for effective heat dissipation (θJA = 80°C/W).

FAQ

What is the minimum output capacitor required for stability with MP2015AGG-Z?

The MP2015AGG-Z is stable with a minimum 0.47µF X5R or X7R ceramic capacitor placed directly at the OUT pin. Larger values (1µF–10µF) improve load transient response and reduce output noise, especially in ADC-sensitive applications. Tantalum or electrolytic capacitors are not recommended due to ESR and temperature drift issues.

Does MP2015AGG-Z include reverse-voltage protection?

No, MP2015AGG-Z lacks internal reverse-voltage protection. Its PMOS pass element contains a body diode that conducts from OUT to IN if V_OUT > V_IN, potentially damaging the IC. An external Schottky diode (cathode to IN, anode to GND) or ideal diode controller is required in backup-battery or hot-swap configurations.

Can MP2015AGG-Z be used in adjustable-output configuration?

Yes-MP2015AGG-Z is the adjustable version. Connect FB to a resistor divider between OUT and GND, with R2 = 1MΩ and R1 calculated via V_OUT = 1.215V × (1 + R1/R2). Output is adjustable from 1.215V to 15V. Fixed-output variants (e.g., MP2015AGG-33) have FB internally connected and require no external resistors.

How does thermal performance differ between QFN-6 and QFN-8 packages?

QFN-6 (MP2015AGG-Z) has θ_JA = 80°C/W and max power dissipation of 1.25W at 25°C ambient; QFN-8 (MP2015AGQ-Z) achieves θ_JA = 48°C/W and 2.08W dissipation. For 150mA at 24V→3.3V drop, QFN-6 dissipates ~3.1W - exceeding its rating - so it must be used within 4.3V–24V input range to stay within safe thermal limits.

What is the EN pin behavior during power-up and shutdown?

The EN pin has 1.32V–1.64V rising threshold and 1.1V–1.42V falling threshold, providing 200mV hysteresis to prevent chatter near the transition point. When pulled low (<1.1V), the device shuts down with 3µA supply current; when high (>1.64V), it starts up in <3ms (with 6.8µF output cap). Leaving EN unconnected disables the regulator.

Is the exposed thermal pad electrically connected internally?

Yes-the exposed pad on the QFN-6 package is internally connected to GND. It must be soldered to a dedicated PCB ground plane with ≥4 thermal vias (0.3mm diameter) to achieve rated θ_JA = 80°C/W and ensure reliable thermal shutdown operation under full 150mA load.

What is the typical output noise level and how can it be reduced?

MP2015AGG-Z exhibits low intrinsic noise, but in high-resolution ADC applications (>12-bit), adding a 22nF feed-forward capacitor across the upper FB resistor reduces output noise significantly. This capacitor is optional for stability but strongly recommended for precision analog supplies where PSRR alone is insufficient.
