Component Status: Active / New Revision
The semiconductor market is constantly evolving, and staying updated with the latest datasheet revisions is critical for design integrity. For engineers working with power management, LED drivers, or battery charging circuits, the designation "pan186cv datasheet new" has been generating significant search traffic over the past quarter.
But what exactly is the Pan186CV? What has changed in the new revision? And how do you interpret the critical electrical characteristics to avoid design flaws?
This article provides a complete, updated analysis of the new Pan186CV datasheet. We will cover pinouts, absolute maximum ratings, thermal characteristics, application circuits, and key differences from previous versions.
The new Pan186CV uses a 5-pin TO-252 package. Here is the updated pinout from the datasheet: pan186cv datasheet new
| Pin No. | Symbol | Description | | :--- | :--- | :--- | | 1 | VIN | Supply input (4.5V to 40V). Bypass with 10µF + 0.1µF ceramic near pin. | | 2 | SW | Switching node. Connect to inductor (33µH–100µH typical). | | 3 | GND | Power ground. Must be connected to exposed thermal pad. | | 4 | FB | Feedback input. Connect resistor divider (Vout = 1.23V * (1 + R1/R2)). | | 5 | EN | Enable input. Logic high (>1.6V) to enable; low (<0.8V) to disable. |
Important PCB Layout Tip from the new datasheet:
Keep the FB trace short and away from the SW node to prevent parasitic coupling, which causes output ripple.
Below are the electrical characteristics extracted directly from the pan186cv datasheet new release. All values are at T(_A) = 25°C unless otherwise noted.

Important Update: The new datasheet increases the recommended maximum junction temperature from 125°C to 140°C (absolute maximum 150°C), allowing higher ambient operation for industrial sensors.
For engineers considering legacy stock vs. new purchases, here is a side-by-side difference matrix.
| Feature | Old Datasheet (v1.0 - 2021) | New Datasheet (v2.1 - 2024) | |---------|------------------------------|------------------------------| | Max Input Voltage | 15V | 18V | | Dropout @ 1A | 330mV | 280mV | | Output Cap Recommendation | 10µF tantalum or ceramic | 22µF ceramic + 1µF film | | Enable Pin Logic | Active high (2.0V min) | Active high (1.2V min - compatible with 1.8V logic) | | Quiescent Current (shutdown) | 5µA max | 1µA max | | Thermal Shutdown Hysteresis | 15°C | 25°C (reduces on/off cycling) | | Package Options | TO-252, SOP-8 | + SOT-223-5 (new) | | ESD Rating (HBM) | ±2kV | ±4kV |
Verdict: The new datasheet represents a significant silicon revision. The PAN186CV is no longer a drop-in replacement – it requires passive component changes but offers superior performance. The new Pan186CV uses a 5-pin TO-252 package
Panasonic's application engineers included a helpful "Do Not" list in the new revision:
The PAN186CV is not a "one size fits all" module, but it excels in specific niches:
Look at the "Environmental Specifications." Many industrial modules claim -40°C to +85°C but derate the RF performance at the extremes. The PAN186CV datasheet includes full RF performance graphs at -40°C and +85°C.
At -40°C, the frequency drift is contained to ±15 ppm (within spec). At +85°C, the output power only droops by 0.5 dB. For a cold storage logger or a solar-powered desert sensor, this module doesn't flinch.
