Description and Introduction

5V/3.3V or Adjustable, Low-Dropout, Low-IQ, 500mA Linear Regulators The MAX603CSA+T is a low-dropout (LDO) voltage regulator manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 11.5V  
- **Output Voltage Options:** 2.5V, 3.0V, 3.3V, 5.0V (fixed)  
- **Output Current:** Up to 500mA  
- **Dropout Voltage:** 120mV (typical) at 100mA load  
- **Quiescent Current:** 50µA (typical)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-Pin SOIC  

### **Descriptions & Features:**  
- **Low-Dropout Operation:** Ensures stable output even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for battery-powered applications.  
- **Thermal Overload Protection:** Prevents damage due to excessive heat.  
- **Short-Circuit Protection:** Safeguards the regulator during output shorts.  
- **No External Capacitors Required:** Stable without additional components (internal compensation).  
- **High Accuracy:** ±2% output voltage tolerance over line, load, and temperature variations.  

This regulator is commonly used in portable electronics, embedded systems, and power-sensitive applications.  

(Note: Always refer to the official datasheet for detailed specifications and application guidelines.)

Application Scenarios & Design Considerations

5V/3.3V or Adjustable, Low-Dropout, Low-IQ, 500mA Linear Regulators

Alternative Part Number

  • LP2951CM --: Adjustable low-dropout linear regulator in SOIC-8 with similar current capability and pin-compatible function, widely available and cost-effective.
  • LT1761ES5-5 --: Low-noise 100mA LDO regulator offering comparable performance in a small package, suitable replacement for low-power regulation applications.
  • MC33269D-5.0 --: 5V fixed low-dropout regulator with 800mA capability in SOIC-8, providing higher current headroom and similar electrical characteristics.
  • LT1763CS8-5 --: Low-noise 500mA LDO in SO-8 with fixed 5V output, a common upgrade path when higher current and lower dropout are needed.
