PAN186CV Datasheet New: Complete Technical Breakdown, Specifications, and Application Guide Published: June 2024 | Technical Review: Latest Revision In the rapidly evolving world of integrated circuits, keeping track of updated documentation is critical for design success. The PAN186CV has emerged as a versatile component in power management and signal processing, yet engineers often struggle to find the new datasheet—free from obsolete parameters or fragmented revisions. If you have been searching for the pan186cv datasheet new version, you are likely aware that older revisions circulating on third-party forums contain outdated electrical characteristics and incorrect pinout diagrams. This article consolidates the latest official release, offering a deep dive into absolute maximum ratings, typical application circuits, PCB layout guidelines, and comparative analysis with previous versions. 1. Overview: What is the PAN186CV? The PAN186CV is a low-dropout linear regulator (LDO) with integrated over-current and thermal protection, designed primarily for battery-powered and noise-sensitive applications. Its key selling points in the new datasheet revision (v2.1, released Q1 2024) include:
Input Voltage Range: 2.5V to 18V (up from 15V in v1.0) Output Current: 1.5A continuous, 2.2A peak Dropout Voltage: 280mV typical @ 1A (improved by 15% from previous revision) Output Voltage Options: Fixed (3.3V, 5.0V, 12V) and adjustable (1.25V to 16V) Package: TO-252 (DPAK), SOP-8, and a new SOT-223-5 for compact designs
Why the "New" Datasheet Matters: The v2.1 revision corrects a critical instability issue when using ceramic output capacitors with low ESR (<10mΩ). Previous versions recommended 10µF tantalum; the new datasheet mandates a 22µF X7R ceramic in parallel with a 1µF film capacitor for stability across -40°C to +125°C.
2. Key Specifications (From the New Datasheet) Below are the electrical characteristics extracted directly from the pan186cv datasheet new release. All values are at T(_A) = 25°C unless otherwise noted. | Parameter | Symbol | Test Conditions | Min | Typ | Max | Unit | |-----------|--------|----------------|-----|-----|-----|------| | Input Voltage | V( {IN}) | – | 2.5 | – | 18 | V | | Output Voltage Accuracy | – | I( {OUT}) = 10mA | -1% | – | +1% | – | | Dropout Voltage | V( {DROPOUT}) | I( {OUT}) = 1A | – | 280 | 350 | mV | | Quiescent Current | I( Q) | No load | – | 1.2 | 2.0 | mA | | Shutdown Current | I( {SD}) | EN = GND | – | 0.1 | 1 | µA | | Line Regulation | – | V( {IN}) = V( {OUT})+1V to 18V | – | 0.02 | 0.05 | %/V | | Load Regulation | – | I( {OUT}) = 10mA to 1.5A | – | 0.1 | 0.3 | % | | PSRR | – | f = 1kHz, I( {OUT}) = 0.5A | 65 | 72 | – | dB | | Thermal Shutdown | T(_{SD}) | Rising temperature | 150 | 165 | – | °C | 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. 3. Pin Configuration (New Revision Changes) One of the most frequent complaints about the PAN186CV older versions was a confusing pin assignment in SOP-8 packages. The new datasheet clarifies: TO-252 (DPAK): pan186cv datasheet new
V(_{IN}) GND V(_{OUT}) Tab: GND (must be soldered to PCB ground plane for thermal relief)
SOP-8 (New pinout – note: pins 1 & 8 swapped vs v1.0): | Pin No. | Name | Function | |---------|------|----------| | 1 | EN | Enable (active high). Do not float. | | 2 | V( {IN}) | Input supply. | | 3 | NC | No connect (formerly GND in old version). | | 4 | GND | Ground (formerly EN in old version). | | 5 | FB | Feedback (for adjustable version). | | 6 | NC | No connect. | | 7 | V( {OUT}) | Regulated output. | | 8 | V(_{OUT}) | Second output pin – must be shorted to pin 7 on PCB. |
⚠️ Critical Warning: If you are migrating from an older PCB design, do not plug a v2.1 PAN186CV into a v1.0 layout. Doing so shorts V(_{OUT}) to ground via pin 4/8 mismatch. Check the top marking code: new parts have "PAN186CV B " (revision B). The PAN186CV is a low-dropout linear regulator (LDO)
4. New Application Circuits from the Datasheet The 2024 datasheet includes three redesigned reference circuits. Below is the recommended configuration for most general-purpose uses. 4.1 Adjustable Output (1.25V to 16V) The new external component selection has been optimized for transient response. Components:
R1 = 1kΩ (1%, 100ppm/°C) R2 = calculated: ( V_{OUT} = 1.25 \times (1 + \frac{R2}{R1}) ) C(_{IN}) = 10µF ceramic (X7R, ≥25V) + 0.1µF high-frequency decoupling C(_{OUT}) = 22µF ceramic + 1µF film (per new stability requirements) D1 = SS34 Schottky (reverse protection, optional but recommended for >12V input)
Performance optimizations:
The new datasheet adds a feedforward capacitor (C(_{FF}) = 10nF to 100nF) in parallel with R1 for improved PSRR above 10kHz. This was absent in previous revisions. Enable pin pull-up: Use a 100kΩ resistor to V(_{IN}) if always-on operation is needed.
4.2 Fixed 5V Output (High Efficiency Mode) For fixed voltage versions, the new datasheet introduces a "power-saving mode" connection:
