Description and Introduction

Triplexed LCD Decoder/Drivers The MAX7231BFIPL is a precision, high-voltage, low-dropout (LDO) linear regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** Adjustable from 4.5V to 40V (set via external resistors).
- **Input Voltage Range:** Up to 40V.
- **Output Current:** 50mA (guaranteed).
- **Dropout Voltage:** Typically 1.5V at full load (50mA).
- **Line Regulation:** 0.01%/V (typical).
- **Load Regulation:** 0.1% (typical).
- **Quiescent Current:** 1.5mA (typical).
- **Operating Temperature Range:** -40°C to +85°C.
- **Package:** 8-pin plastic DIP (PDIP).

### **Descriptions:**
- The MAX7231BFIPL is designed for applications requiring a stable, high-voltage output with low noise and high accuracy.
- It includes internal current limiting and thermal shutdown protection.
- Suitable for industrial, automotive, and instrumentation applications.

### **Features:**
- **High-Voltage Operation:** Supports input voltages up to 40V.
- **Low Dropout:** Efficient regulation even with small input-output differentials.
- **Adjustable Output:** External resistors allow precise voltage setting.
- **Thermal Protection:** Shuts down if overheating occurs.
- **Current Limiting:** Protects the device from excessive load currents.
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.

This information is based solely on the manufacturer's datasheet. For detailed application notes, refer to Maxim Integrated's documentation.

Application Scenarios & Design Considerations

Alternative Part Number

  • ICM7211AIPL --: Four-digit seven-segment LCD display driver in a 40-pin DIP, functionally similar to the MAX7231 display driver family and widely available as a cross-reference.
  • ICL7136CPL --: Low-power 3.5-digit A/D converter with display drive in a DIP package, often used as an alternative in similar display-driver applications.
  • TC7107CPL --: 3.5-digit LED/LCD display driver A/D converter in a 40-pin DIP, a common second-source option for display-driver designs.
  • ICL7135CPI --: 4.5-digit ADC with similar display-driver function and DIP package, widely available as a MAX7231 replacement in panel-meter designs.
  • ICL7107CPL --: Classic 3.5-digit LED display ADC driver in DIP package, a common drop-in style alternative when full MAX7231 features are not required.
