Description and Introduction

High-Frequency, Regulated, 200mA, Inverting Charge Pump The MAX889SESA is a linear regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual details about the part:

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now part of Analog Devices)  

### **Specifications:**  
- **Output Voltage:** Adjustable (via external resistors) or fixed options available  
- **Output Current:** Up to **150mA**  
- **Input Voltage Range:** **4V to 11.5V**  
- **Dropout Voltage:** **120mV (typical) at 100mA load**  
- **Quiescent Current:** **40µA (typical)**  
- **Low-Battery Detector:** Integrated with adjustable threshold  
- **Shutdown Current:** **0.1µA (typical)**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **8-pin SOIC (MAX889SESA)**  

### **Descriptions:**  
- The MAX889SESA is a low-dropout (LDO) linear regulator designed for battery-powered applications.  
- It features an ultra-low quiescent current, making it suitable for portable and low-power devices.  
- Includes a low-battery detector to monitor input voltage levels.  
- Offers both fixed and adjustable output voltage configurations.  

### **Features:**  
- **Ultra-Low Quiescent Current (40µA)**  
- **Low Dropout Voltage (120mV @ 100mA)**  
- **Adjustable or Fixed Output Voltage Options**  
- **Integrated Low-Battery Detector**  
- **Low Shutdown Current (0.1µA)**  
- **Thermal and Short-Circuit Protection**  
- **Stable with Low-ESR Ceramic Capacitors**  

This information is based on the manufacturer's datasheet for the MAX889SESA.

Application Scenarios & Design Considerations

High-Frequency, Regulated, 200mA, Inverting Charge Pump

Alternative Part Number

  • LM2662M --: Switched-capacitor voltage inverter in SOIC-8, functionally similar to the MAX889 charge-pump inverter with comparable current capability.
  • ICL7660SCPA --: Classic charge-pump voltage converter/inverter, widely available and pin-compatible in function for negative supply generation.
  • LT1054CS8 --: Switched-capacitor voltage converter with regulated output and higher output current, suitable drop-in functional replacement in SOIC-8.
  • ICL7660ACPA --: Classic charge-pump voltage inverter offering similar inverting function and current range; available in DIP/SOIC and commonly used as a drop-in alternative where exact regulation is not critical.
  • TC7660EOA --: Low-cost switched-capacitor voltage converter in SO-8 that provides inverting output comparable to MAX889, suitable for less demanding load conditions.
