- **Output Current:** Up to 500mA  
- **Dropout Voltage:** 210mV (typical) at 500mA load  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Low Quiescent Current:** 17µA (typical)  
- **High PSRR:** 75dB at 1kHz  
- **Thermal Shutdown & Overcurrent Protection**  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**  
- **Package:** VSSOP-8 (DCQ)  

### **Applications:**  
- Battery-powered devices  
- Portable electronics  
- DSP and FPGA power supplies  
- Noise-sensitive analog circuits  

This information is based solely on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

Low Input Voltage, 1-A Low-Dropout Linear Regulators with Supervisor 6-SOT-223 -40 to 125

Alternative Part Number

  • LP38692SD-1.5 --: 1.5V fixed low-dropout linear regulator in a similar small package, offering comparable output current and low noise as a direct functional substitute.
  • MIC29152WT --: Adjustable low-dropout regulator that can be set to 1.5V, with higher current capability and similar dropout performance, suitable for the same rail.
  • LT1963AEQ-1.5 --: 1.5V fixed low-noise LDO regulator with comparable dropout voltage and current rating, usable as an alternative with minor layout adjustments.
