- **Output Current:** 300mA  
- **Dropout Voltage:** 120mV (typical) at 300mA load  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Accuracy:** ±1.5% over line, load, and temperature  
- **Quiescent Current:** 50µA (typical)  
- **Shutdown Current:** <1µA  
- **PSRR (Power Supply Rejection Ratio):** 70dB at 1kHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 5-Pin SOT23  

### **Descriptions:**
- The MAX8887EZK30-T is a high-performance, low-dropout linear regulator designed for battery-powered applications.  
- It provides a fixed 3.0V output with high accuracy and low noise.  
- The device features low quiescent current, making it suitable for portable and power-sensitive applications.  
- It includes thermal shutdown and current-limit protection.  

### **Features:**
- **Low Dropout Voltage:** 120mV at 300mA load  
- **Low Quiescent Current:** 50µA (typical)  
- **High PSRR:** 70dB at 1kHz  
- **Thermal and Current-Limit Protection**  
- **Stable with Low-ESR Ceramic Capacitors**  
- **Tiny 5-Pin SOT23 Package**

Application Scenarios & Design Considerations

Low-Dropout, 300mA Linear Regulators in SOT23

Alternative Part Number

  • TPS7A2030PDBVR --: Low-dropout 3.0V linear regulator in SOT-23-5 with similar current capability and low quiescent current, a common cross for MAX8887 3.0V LDOs.
  • LP2985AIM5-3.0 --: 3.0V fixed LDO in SOT-23-5 with low noise and shutdown pin, widely used as a drop-in style replacement for small MAX LDO regulators.
  • MIC5205-3.0YM5 --: 3.0V fixed LDO in SOT-23-5 with enable pin and low dropout, functionally similar to the MAX8887 3.0V regulator family.
