LM120H-5.0 Overview

The LM120H-5.0 is a linear voltage regulator manufactured by Texas Instruments (TI)

It belongs to the LM120 series of high-performance, low-dropout (LDO) regulators designed to provide a stable 5.0V output voltage from higher input voltages. 

Ideal for applications requiring low noise and high power supply rejection ratio (PSRR), it ensures reliable power regulation in both commercial and industrial systems.

Key Functions

1. Stable Voltage Regulation

  • Fixed 5.0V Output: Delivers a precise output voltage with a tolerance of ±2% over the full input voltage and temperature range.
  • Low Dropout Voltage: Maintains regulation with a dropout voltage of typically 1.3V at 1A load, 
  • making it suitable for applications with limited input voltage headroom (e.g., battery-powered systems).

2. High Current Capability

  • Output Current: Supports continuous output currents up to 1A
  • with short-circuit current limiting and thermal overload protection to prevent damage from overloads.

3. Low Noise and High PSRR

  • Low Output Noise: Generates minimal output noise (typically 30μV rms in the audio band), 
  • making it suitable for noise-sensitive applications like audio amplifiers or analog circuits.
  • High PSRR: Offers the PSRR of 62dB at 1kHz, effectively suppressing input voltage ripple and noise, 
  • which is critical for stable operation in noisy environments.

4. Thermal and Overload Protection

  • Thermal Shutdown: Automatically disables the output if the junction temperature exceeds ~175°C, 
  • preventing overheating in high-power or fault conditions.
  • Short-Circuit Current Limiting: Limits the output current to a safe level (typically 1.5A) during short-circuit events, 
  • protecting both the regulator and downstream components.

5. Simple External Components

  • Requires only an input capacitor (≥1μF, ceramic recommended) and an output capacitor 
  • (≥10μF, ceramic or electrolytic) for stable operation, reducing design complexity and bill of materials (BOM) cost.

Applications

The LM120H-5.0 is widely used in systems requiring a stable, low-noise 5V power supply. Below are its key application areas:

1. Consumer Electronics

  • Portable Devices: Powers tablets, e-readers, and handheld gaming consoles,
  •  where low dropout voltage and high efficiency extend battery life.
  • Audio/Video Equipment: Provides clean power for audio amplifiers,
  •  DACs (digital-to-analog converters), and AV receivers, minimizing noise interference in signal chains.

2. Industrial and Control Systems

  • Industrial Automation: Regulates power for PLCs (programmable logic controllers), sensors, 
  • and actuators in factory environments, ensuring reliable operation despite input voltage fluctuations.
  • Test and Measurement Instruments: Used in oscilloscopes, multimeters, 
  • and data acquisition systems to maintain precise voltage levels for accurate measurements.
