- **Output Voltage:** Adjustable (via external resistors)  
- **Output Current:** Up to **150mA**  
- **Switching Frequency:** **300kHz** (typical)  
- **Efficiency:** Up to **90%**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package Type:** **SOT-23-5**  

### **Descriptions:**  
- A **step-up DC-DC converter** designed for low-voltage applications.  
- Suitable for battery-powered devices, portable electronics, and IoT applications.  
- Features **low standby current** and **built-in protection circuits**.  

### **Features:**  
- **Low Start-up Voltage:** Operates from **2.0V** input.  
- **PWM Control:** Ensures stable output voltage.  
- **Soft Start Function:** Prevents inrush current.  
- **Overcurrent Protection (OCP):** Safeguards the IC and load.  
- **Compact Package:** **SOT-23-5** for space-constrained designs.  

For detailed application notes, refer to the **datasheet** from **ABLIC Inc.** (formerly Seiko Instruments).

Application Scenarios & Design Considerations

HIGH WITHSTAND-VOLTAGE VOLTAGE REGULATOR WITH RESET FUNCTION

Alternative Part Number

  • S-875045CUP-ACAT2G --: ABLIC is the successor of Seiko Instruments' semiconductor business, so this is the same part under the new brand; functionally identical and the most direct replacement.
  • S-875045CUP-ACAT2U --: Same S-875045 series voltage detector from ABLIC with equivalent electrical specifications; differs only in packaging/ordering code, suitable as a drop-in alternative.
  • AP7361C-33E-13 --: Low-dropout linear regulator with 3.3V fixed output and similar current capability, suitable replacement for the S-875045 series in many applications.
  • MIC5219-3.3YM5-TR --: Low-noise 3.3V LDO regulator with comparable dropout and load current, commonly used as a drop-in alternative for S-8750 series regulators.
  • LP2985AIM5-3.3/NOPB --: Widely available 3.3V low-dropout regulator with stable performance and similar package options, offering a reliable cross-reference.
