onsemi NCV8606MN50T2G

Overview

NCV8606MN50T2G from onsemi is an automotive-grade, 5.0 V fixed-output LDO regulator delivering up to 500 mA output current with 2% output voltage tolerance over −40°C to +125°C ambient, 450 mV dropout at 500 mA, and 50 µV_RMS output noise (10 Hz–100 kHz). It features active-high enable control, thermal shutdown, current limiting, and operation with low-ESR ceramic capacitors - designed for battery-powered infotainment and ADAS power rails.

For engineers reviewing the NCV8606MN50T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, low ground current (145–180 µA), high PSRR (62 dB @ 120 Hz), 4 kV HBM ESD rating, and compatibility with compact DFN6 3×3.3 mm layouts in space-constrained automotive modules.

Technical Context

The NCV8606MN50T2G integrates a PMOS pass transistor with internal current limit (675 mA) and thermal shutdown (175°C trip, 10°C hysteresis). Its enable input allows precise system-level power sequencing, while the SENSE/ADJ pin connects directly to the output capacitor for fixed-voltage operation - eliminating external feedback components.

Designed for automotive environments, it operates across 1.5 V to 6.0 V input range, supports stable regulation down to 1.5 V input (for 5.0 V output), and maintains <30 mV load regulation (1–500 mA) and <10 mV line regulation - enabling robust performance under battery voltage sag and dynamic load transients.

Key Specifications

Pinout & Package

NCV8606MN50T2G is housed in a thermally enhanced DFN6 3.0×3.3 mm package (Case 506AX) with exposed pad tied to GND for improved heat dissipation. Pin 1 and Pin 6 are both Vin inputs and must be externally shorted to support full 500 mA output capability.

FAQ

What is the maximum input voltage for the NCV8606MN50T2G?

The absolute maximum input voltage for the NCV8606MN50T2G is 6.5 V. However, the recommended operating input range is 1.5 V to 6.0 V. For reliable 5.0 V output regulation, minimum input must be at least V_OUT + V_DO (i.e., 5.15 V typical), or 1.5 V - whichever is higher. Exceeding 6.5 V risks permanent damage per the Absolute Maximum Ratings table.

Does the NCV8606MN50T2G require external resistors to set the output voltage?

No, the NCV8606MN50T2G is a fixed 5.0 V output LDO. Its SENSE/ADJ pin connects directly to the output capacitor (not to a resistor divider) to close the internal feedback loop. External resistors are only required for adjustable versions like NCV8606MNADJT2G - not for the NCV8606MN50T2G.

How does the enable pin function on the NCV8606MN50T2G?

The EN pin on the NCV8606MN50T2G is active-high: applying ≥0.9 V enables regulation, while ≤0.4 V disables output and reduces ground current to ≤1 µA. The enable transition times are 12–30 µs depending on output voltage. If unused, EN must be tied to Vin to ensure continuous operation - floating is not permitted.

Is the NCV8606MN50T2G compatible with ceramic output capacitors?

Yes, the NCV8606MN50T2G is fully stable with ceramic output capacitors ≥1.0 µF and requires no minimum ESR. It has been characterized with Murata GRM219R71E105K (1 µF, X7R, 0805) and GRM21BR71A106K (10 µF, X7R, 0805). Larger values improve load transient response and noise rejection without risk of oscillation.

What thermal considerations apply to the NCV8606MN50T2G in automotive designs?

The NCV8606MN50T2G uses a DFN6 package with exposed thermal pad connected to GND. Its R_JA is 75°C/W on 645 mm² 1 oz copper. At 25°C ambient and 500 mA load, max power dissipation is ~1.3 W before reaching 125°C junction limit. Layout must maximize copper area under the pad and use multiple vias to inner ground planes to sustain operation in under-hood environments up to 125°C ambient.
