Description and Introduction

Low-Dropout, 300mA Linear Regulators in SOT23 The MAX8887EZK29+T is a low-dropout (LDO) linear regulator manufactured by **MAXIM** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 2.9V (fixed)  
- **Output Current:** 300mA  
- **Dropout Voltage:** 120mV (typical at 300mA load)  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Quiescent Current:** 40µA (typical)  
- **Accuracy:** ±2% over line, load, and temperature  
- **Package:** 5-Pin SOT23  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
- The MAX8887EZK29+T is a low-noise, low-dropout linear regulator designed for battery-powered and portable applications.  
- It provides a stable 2.9V output with high PSRR (Power Supply Rejection Ratio) and low quiescent current.  
- The device includes thermal shutdown and current-limit protection.  

### **Features:**  
- **Low Dropout Voltage:** 120mV at 300mA  
- **Low Quiescent Current:** 40µA (improves battery life)  
- **High PSRR:** 70dB at 1kHz  
- **Thermal and Short-Circuit Protection**  
- **Stable with Low-ESR Ceramic Capacitors**  
- **Tiny 5-Pin SOT23 Package**  

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

Application Scenarios & Design Considerations

Low-Dropout, 300mA Linear Regulators in SOT23

Alternative Part Number

  • TPS7A2029PDBVR --: Low-noise 200mA LDO in SOT-23-5 with fixed 2.9V output, similar dropout and current rating, widely available and pin-compatible in function.
  • LP5907MFX-2.9/NOPB --: Ultra-low-noise 250mA LDO with 2.9V fixed output in SOT-23-5, excellent PSRR and low quiescent current, a strong functional replacement.
  • AP2112K-2.9TRG1 --: 600mA CMOS LDO with 2.9V fixed output in SOT-23-5, higher current capability and low dropout, cost-effective alternative for similar applications.
