Description and Introduction

Dual-Output LDO Voltage Regulators The TPS70158PWPR is a dual-output, low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage (Primary):** 1.5V (fixed)  
- **Output Voltage (Secondary):** Adjustable (1.2V to 5.5V) or fixed options available  
- **Output Current (Primary):** Up to 500mA  
- **Output Current (Secondary):** Up to 250mA  
- **Dropout Voltage:** 300mV (typical) at full load  
- **Quiescent Current:** 85µA (typical)  
- **Power-On Reset (POR) Delay:** Adjustable  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-pin HTSSOP (PWPR)  

### **Descriptions:**  
- The TPS70158PWPR is a dual-output LDO regulator designed for applications requiring stable power supplies with low noise and high efficiency.  
- It features independent enable controls for each output, allowing flexible power sequencing.  
- The device includes built-in power-on reset (POR) monitoring for system reliability.  
- It is suitable for battery-powered and noise-sensitive applications.  

### **Features:**  
- **Dual Independent Outputs:** Primary (1.5V fixed) and secondary (adjustable or fixed).  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Adjustable Power-On Reset (POR):** Configurable delay for system initialization.  
- **Thermal and Overcurrent Protection:** Safeguards against excessive heat and short circuits.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors for cost-effective designs.

Application Scenarios & Design Considerations

Dual-Output LDO Voltage Regulators

Alternative Part Number

  • LP3965EMP-1.8 --: Dual low-dropout linear regulator in a similar power package with 1.8V fixed output, suitable replacement for the TPS70158 dual LDO function.
  • MIC5219-1.8YM5 --: Low-noise 1.8V LDO regulator with comparable current capability and thermal performance, different series and prefix for easy distinction.
  • LT1963AEQ-1.8 --: High-performance 1.8V low-dropout regulator with low quiescent current and stable output, a robust alternative from a different vendor family.
  • LP38692MP-1.8 --: Low-dropout linear regulator in a different series offering a 1.8V fixed output, suitable as a functional substitute for the 1.8V rail of the TPS70158 dual regulator.
