M215HW03-V1 PDF Datasheet – 21.5 Inch, TFT LCD Module

Posted on by pinout

TFT LCD (Thin-Film Transistor Liquid Crystal Display) module is a type of flat-panel display that uses thin-film transistor technology to improve the image quality and response time of traditional LCDs. TFT LCD modules consist of a layer of liquid crystal material sandwiched between two sheets of glass or plastic substrates, with each pixel controlled by its own thin-film transistor.

TFT LCD modules are widely used in various electronic devices such as smartphones, tablets, laptops, gaming devices, and automotive displays because they offer high resolution, high contrast, and fast refresh rates.

  • Internal thermal overload protection
  • Output transition safe-area compensation
  • Short-circuit current limiting protection
  • Low lot-to-lot variation for consistent performance

Absolute Maximum Ratings (Tc = 25 °C)

Parameter Symbol Value Unit
Input Voltage VIN 35 V
Output Current IO 1.5 A
Power Dissipation Ptot Internally Limited –
Junction Temperature Tj 150 °C
Storage Temperature Tstg -65 to 150 °C

Design Notes

  • Maintain input voltage at least 2V higher than output (dropout consideration)
  • Use input and output capacitors (e.g., 0.33µF and 0.1µF) for stability
  • Heat sinking is required for high current or high input-output voltage differential
  • Thermal shutdown protects the device under overload conditions
  • Ensure proper PCB layout to minimize noise and improve regulation

Typical Circuit Usage

  • Linear regulated power supply stages
  • Microcontroller and logic circuit power rails
  • Analog signal conditioning circuits
  • Battery-powered systems requiring regulated 8V output
  • Post-regulation after DC-DC converters

How to Choose This Part

  • Select when a fixed 8V output is required with simple implementation
  • Ideal for low-noise analog applications compared to switching regulators
  • Ensure thermal design is adequate for power dissipation
  • Use when input voltage is within safe operating limits
  • Not suitable for high-efficiency designs due to linear regulation losses

Applications

  • Power adapters and regulated DC supplies
  • Embedded systems and development boards
  • Audio and instrumentation circuits
  • Industrial control systems
  • Consumer electronics power regulation

Alternative / Equivalent Products

  • LM7808 (standard 8V regulator)
  • L7808 (STMicroelectronics equivalent)
  • KA7808 (Fairchild equivalent)
  • UA7808 (Texas Instruments version)
  • LM317 (adjustable voltage regulator alternative)
