Description and Introduction

3.3 V, Ultra-low-noise, high PSRR, low-dropout, 120 mA linear regulator The MAX8511EXK33-T is a low-dropout linear regulator (LDO) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Manufacturer:**  
- **MAXIM (now Analog Devices)**  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 120mV (typical at 150mA load)  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Quiescent Current:** 40µA (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Line Regulation:** 0.01%/V (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SC-70 (5-Pin)  

### **Descriptions:**  
- The MAX8511EXK33-T is a low-power, low-dropout linear regulator designed for battery-powered applications.  
- It provides a stable 3.3V output with low noise and high PSRR (Power Supply Rejection Ratio).  
- Features an enable pin (EN) for shutdown mode, reducing power consumption when not in use.  

### **Features:**  
- **Ultra-Low Dropout Voltage:** 120mV at 150mA load.  
- **Low Quiescent Current:** 40µA (typical) for improved efficiency.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Thermal and Short-Circuit Protection:** Ensures safe operation under fault conditions.  
- **Enable Pin (EN):** Allows shutdown mode, reducing current to <1µA.  
- **Small Package:** SC-70 (5-Pin) for space-constrained applications.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

3.3 V, Ultra-low-noise, high PSRR, low-dropout, 120 mA linear regulator

Alternative Part Number

  • LP2985AIM5-3.3 --: Low-dropout 3.3V linear regulator in SOT-23-5 with similar current capability and pin-compatible layout, widely available and cost-effective.
  • TLV70233PDBVR --: 3.3V fixed LDO in SOT-23-5 with low quiescent current and good PSRR, suitable drop-in replacement for small portable designs.
  • AP2112K-3.3TRG1 --: 3.3V LDO regulator in SOT-23-5 offering comparable dropout and output current, commonly used as an alternative to MAX8511 series.
