Monolithic Power Systems Inc. MP2014GZD-36-P

Overview

MP2014GZD-36-P from Monolithic Power Systems is a 40V-input, 500mA fixed-output linear regulator in TO252-5 package with 3.6V output, ±2% accuracy, 10µA quiescent current, and programmable power-good delay. It delivers stable low-power bias for microcontrollers in high-voltage battery systems such as automotive body control modules and industrial sensors.

For engineers reviewing the MP2014GZD-36-P datasheet, MP2014GZD-36-P pinout, MP2014GZD-36-P application, or MP2014GZD-36-P equivalent, key selection criteria include dropout voltage at 500mA (≤1.3V), thermal shutdown threshold (165°C), PGDL programmability, GND-connected exposed pad requirement, and compatibility with ≥0.47µF ceramic output capacitors.

Technical Context

The MP2014GZD-36-P implements a PMOS pass transistor architecture enabling ultra-low quiescent current (10µA typ.) and wide 3V–40V input operation. Its internal current limiting (550–1450mA) and thermal shutdown (165°C with 30°C hysteresis) provide robust fault protection without external components.

It integrates an open-drain Power Good (PG) output with 93% VOUT rising threshold and user-programmable delay via external capacitor on PGDL pin (1.65V threshold, 3–9µA charging current). The regulator stabilizes with only 0.47µF ceramic output capacitance, reducing BOM count and PCB area.

Key Specifications

Pinout & Package

MP2014GZD-36-P is housed in a thermally enhanced TO252-5 (DPAK) package with exposed pad electrically connected to GND. The exposed pad must be soldered to a large PCB copper area for effective heat dissipation and EMI reduction.

FAQ

What is the minimum output capacitor required for stability?

The MP2014GZD-36-P is stable with a minimum 0.47µF X5R or X7R ceramic capacitor on the output pin. Larger values (up to 22µF) improve load transient response and reduce output ripple. Tantalum or aluminum electrolytic capacitors are not recommended due to ESR and aging effects that may compromise stability.

Can the PG pin be left unconnected?

No. The PG pin is an open-drain output and must be pulled up to VOUT (or another compatible voltage ≤15V) via a resistor (typically 100kΩ). Leaving it floating will prevent proper power-good signaling and may cause undefined behavior during startup or fault conditions.

How is the PG delay time calculated for a given PGDL capacitor?

Delay time t_PGDL (ms) = C_PGDL (nF) × 1.65V / I_PGDL (µA), where I_PGDL is 3–9µA (typ. 5.5µA). For example, a 47nF capacitor yields ~11ms delay using the typical charging current. This equation is derived from internal constant-current charging of the PGDL node to its 1.65V threshold.

Is the exposed 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 provides both electrical grounding and primary thermal conduction path-failure to do so degrades thermal performance and may trigger premature thermal shutdown.

Does MP2014GZD-36-P support adjustable output voltage?

No. MP2014GZD-36-P is a factory-trimmed fixed-output device delivering 3.6V ±2%. It does not include feedback pins or external resistor networks for adjustment. For adjustable variants, refer to MPS's MP2013 series, which offers external resistor-set outputs but with different pinout and feature set.

What is the maximum allowable power dissipation at +85°C ambient?

Using θ_JA = 55°C/W and T_J(MAX) = 150°C, maximum continuous power dissipation at T_A = +85°C is (150 – 85) / 55 ≈ 1.18W. This corresponds to ~330mA at 3.6V output with 36V input (P_D = (36 – 3.6) × 0.33 ≈ 1.07W), confirming safe operation within thermal limits under typical conditions.

Are there any special PCB layout requirements?

Yes. Place input and output ceramic capacitors as close as possible to their respective pins. Connect GND pin and exposed pad to a large, low-impedance ground plane. Avoid routing noisy traces (e.g., switching node, clock lines) near the IN, OUT, or PGDL pins to prevent coupling into the regulation loop or PG timing circuit.
