Introduction
LM2990S-5.0/NOPB Negative Voltage Regulator
Designed to deliver a clean, stable negative supply in dual-rail systems, automotive, and industrial applications.
Core Functions
Fixed −5V Negative Regulation
Provides precise −5V output with ±5% accuracy across full load, line, and temperature ranges.
High Current Capability
Supports continuous load currents up to 1A with peak capability exceeding 1A for short transients.
Low Dropout Voltage
Typical dropout of 0.6V at 1A, guaranteed maximum 1V over entire operating temperature range for efficient operation.
Power Efficiency
Typical quiescent current of 1mA at 1A load; limited to 9mA typical in dropout mode for optimal power efficiency.
Robust Protection Features
- Short-circuit proof with internal current limiting
- Thermal shutdown with hysteresis for enhanced reliability
Easy Integration
Standard 3-terminal pinout for easy drop-in replacement and D²PAK (TO-263-3) surface-mount package for high-power dissipation and compact PCB integration.
Typical Applications
- Dual-supply systems for op-amps, data converters, and analog circuits requiring bipolar supplies
- Post-switcher regulator for noise-sensitive analog and RF circuits
- Automotive electronics in harsh environments (−40°C to +125°C)
- Industrial control and test equipment including PLCs and measurement instruments
- Battery-powered devices for extended runtime in portable systems
- Current sink applications for LED drivers, load testing, and biasing
