Monolithic Power Systems Inc. MP2013GQ-P

Overview

MP2013GQ-P from Monolithic Power Systems is a 40V-input, 150mA low-dropout linear regulator with 3.2µA quiescent current, ±2% output voltage accuracy, and fixed 3.3V output. It operates across –40°C to +125°C junction temperature and delivers stable regulation for ultra-low-power microcontrollers in high-voltage battery systems such as automotive body electronics and industrial sensors.

For engineers reviewing the MP2013GQ-P datasheet, MP2013GQ-P pinout, MP2013GQ-P application, or MP2013GQ-P equivalent, this device is selected for its combination of wide input range (2.5V–40V), minimal dropout (740mV at 150mA), ceramic-capacitor stability (≥0.47μF), thermal shutdown protection, and QFN8 package thermal performance-critical for space-constrained, thermally demanding designs.

Technical Context

The MP2013GQ-P uses a PMOS pass transistor architecture enabling low dropout and reverse-voltage blocking via external diode integration. Its internal feedback reference is trimmed to 1.215V (±2%), supporting precise fixed-output regulation without external resistors.

Thermal shutdown activates at 150°C with 20°C hysteresis, and current limiting caps peak output at 270mA while sustaining 150mA continuous load. The dual-input pins (IN1/IN2) decouple power delivery for internal logic and pass element, improving PSRR and transient immunity.

Key Specifications

Pinout & Package

MP2013GQ-P is housed in a thermally enhanced QFN8 (3mm × 3mm) package with an exposed thermal pad that must be soldered to a PCB ground plane for optimal power dissipation (θJA = 48°C/W).

FAQ

What is the maximum continuous output current for MP2013GQ-P?

The MP2013GQ-P is specified for 150mA continuous output current at ambient temperatures up to +85°C with proper PCB copper area for thermal dissipation. Peak current limit is 270mA, but sustained operation above 150mA requires derating based on θJA (48°C/W) and ambient temperature to avoid thermal shutdown.

Can MP2013GQ-P operate with a 0.47μF output capacitor?

Yes-MP2013GQ-P is explicitly characterized and guaranteed stable with ceramic output capacitors as low as 0.47μF (X5R/X7R dielectric). This eliminates need for larger, less reliable electrolytic or tantalum capacitors and reduces PCB area and cost.

Is external reverse-voltage protection required?

Yes-due to the internal PMOS body diode, reverse current can flow from OUT to IN if output voltage exceeds input (e.g., backup battery scenario). An external Schottky diode in series with IN1 is recommended to block reverse conduction and prevent device damage.

What is the purpose of the IN2 pin?

IN2 supplies bias current to the internal control circuitry independently from the main pass transistor path. It must be tied directly to IN1 to ensure stable operation; separating them causes regulation failure or oscillation due to mismatched supply domains.

Does MP2013GQ-P require a feedforward capacitor for stability?

No-the 0.47μF minimum output capacitor ensures unconditional stability. A 22nF feedforward capacitor across the upper FB resistor may reduce output noise in high-resolution ADC applications but is optional and not required for basic regulation.

How does thermal shutdown behave during overload?

When junction temperature reaches 150°C, MP2013GQ-P shuts down output and enters thermal hysteresis mode. It remains off until temperature drops by ≥20°C (to ≤130°C), then automatically resumes regulation-no external reset or intervention needed.

What is the FB pin voltage for the MP2013GQ-P fixed 3.3V version?

The internal feedback reference is 1.215V ±1.5%, and the internal resistor divider sets VOUT = 3.3V. The FB pin is internally connected and must remain floating-no external components are connected to FB in fixed-output configurations.
