Monolithic Power Systems Inc. MP2014GZD-36-Z

Overview

MP2014GZD-36-Z from Monolithic Power Systems is a 40V-input, 500mA fixed-output linear regulator in TO252-5 package, delivering 3.3V ±2% with 10µA quiescent current and 700mV dropout at 300mA load. It integrates programmable power-good delay (via PGDL pin), thermal shutdown (165°C), and short-circuit protection-designed for ultra-low-power microcontrollers in automotive battery-supplied systems.

For engineers reviewing the MP2014GZD-36-Z datasheet, MP2014GZD-36-Z pinout, MP2014GZD-36-Z application, or MP2014GZD-36-Z equivalent, key selection criteria include input voltage range (3–40V), output accuracy (±2%), PGDL programmability, thermal shutdown hysteresis (30°C), and ceramic capacitor stability (≥0.47µF).

Technical Context

The MP2014GZD-36-Z employs a PMOS pass transistor architecture enabling low dropout and minimal quiescent current across its full 3V–40V input range. Its internal current limit (~900mA peak) and thermal shutdown circuitry operate independently to ensure robust fault handling without external components.

Power Good functionality uses an open-drain MOSFET with 93% VOUT rising threshold and 5% hysteresis; PGDL pin enables precise delay tuning via external capacitor (e.g., 47nF yields 6–14ms delay), supporting sequencing-critical applications like multi-rail industrial controllers.

Key Specifications

Pinout & Package

FAQ

What is the minimum output capacitor required for stability?

The MP2014GZD-36-Z is stable with a minimum 0.47µF X5R or X7R ceramic capacitor on the output. Larger values (up to 22µF) improve load transient response and reduce output ripple, but are not required for basic stability per the datasheet's characterization conditions.

Can the PG pin drive an LED directly?

No-the PG pin is an open-drain MOSFET with 1mA sink capability and 0.4V max saturation voltage. Driving an LED requires a series current-limiting resistor and external pull-up to VOUT or another supply; typical configuration uses a 100kΩ resistor to VOUT for status indication.

How does the PGDL capacitor value affect startup timing?

PGDL delay time (t_PGDL) scales linearly with capacitor value: t_PGDL ≈ C_PGDL × 1.65V / I_PGDL, where I_PGDL is 3–9µA. A 47nF capacitor yields 6–14ms delay; doubling capacitance doubles the delay, enabling precise synchronization with downstream regulators or processors.

Is the exposed thermal pad electrically isolated?

No-the exposed pad on the TO252-5 package is internally connected to the GND pin and must be soldered to a PCB ground plane. This connection serves both thermal dissipation (reducing θJA to 55°C/W) and electrical grounding; floating or insulated mounting degrades thermal performance and may cause instability.

Does the MP2014GZD-36-Z support adjustable output voltage?

No-it is a fixed-output device configured for 3.3V. The MP2014 family offers multiple fixed-voltage variants (e.g., 1.8V, 2.5V, 5.0V), but no adjustable version exists. Output voltage is trimmed at wafer test and cannot be modified externally via feedback resistors.

What is the maximum continuous output current at 85°C ambient?

At T_A = 85°C, maximum continuous output current is limited by thermal dissipation: P_D(MAX) = (T_J(MAX) − T_A) / θ_JA = (150°C − 85°C) / 55°C/W ≈ 1.18W. With V_DROP ≈ 700mV at 300mA, usable current remains ~500mA under typical PCB layout; derating is recommended above 70°C ambient.

How does the power-good hysteresis prevent chatter during brown-out?

The PG pin asserts high at 93% V_OUT and releases at 88% V_OUT, providing 5% hysteresis. This prevents rapid toggling during marginal input conditions-e.g., during automotive cranking-ensuring clean, glitch-free reset signaling to the host microcontroller without software debouncing.
