Product Introduction

Overview

The LP2950ACZ-5.0RAG is a micropower low dropout (LDO) linear voltage regulator produced by onsemi. This device is designed to maintain proper regulation with an extremely low input-to-output voltage differential, making it ideal for battery-powered equipment where extending battery life is crucial. The LP2950 series features a very low quiescent bias current of 75 µA and can supply output currents in excess of 100 mA. It also includes internal current and thermal limiting protection for enhanced reliability.

Key Features

  • Low Quiescent Bias Current: 75 µA, which helps in extending battery life in portable devices.
  • Low Input-to-Output Voltage Differential: 50 mV at 100 mA and 380 mV at 100 mA, ensuring efficient voltage regulation.
  • Precise Output Voltage: Available in fixed output voltages of 5.0 V, 3.3 V, and 3.0 V with an initial output voltage tolerance of ±0.5% for 'A' suffix devices.
  • Adjustable Output Voltage: The LP2951 version can be programmed for any output voltage between 1.25 V and 29 V using external resistors.
  • Internal Protection: Includes internal current and thermal limiting protection to prevent device damage.
  • Shutdown Feature: The LP2951 has a shutdown input that allows a logic level signal to turn-off or turn-on the regulator output.
  • Error Output: The LP2951 features an error output that can signal external circuitry of an out-of-regulation condition or serve as a microprocessor power-on reset.

Applications

The LP2950ACZ-5.0RAG is ideally suited for battery-powered computer, consumer, and industrial equipment. Its low quiescent bias current and low input-to-output voltage differential make it particularly useful in applications where extending the useful battery life is desirable.
