Detailed Description for LM79L05ACMX/NOPB
Product Overview
The LM79L05ACMX/NOPB from Texas Instruments is a single-output linear voltage regulator that provides a fixed negative -5V rail. It uses an 8-SOIC surface-mount package with a 3.90 mm body width and is suitable for board-level power management where a negative voltage rail is required. The device supports a maximum input voltage of -35V, delivers up to 100mA output current, and includes over-temperature and short-circuit protection. Its 6 mA quiescent current and 50dB power-supply rejection at 120Hz are specified for operation from 0°C ~ 70°C.
Key Features
- Single regulator section with fixed negative -5V output.
- 100mA output current and 6 mA quiescent current.
- Maximum input voltage rating of -35V.
- 50dB power-supply rejection at 120Hz.
- Over-temperature and short-circuit protection.
- 8-SOIC surface-mount package, 0.154 in, 3.90 mm width.
- Operating temperature range of 0°C ~ 70°C.
Applications
- Negative-rail generation for analog circuitry requiring a fixed -5V supply.
- Biasing of mixed-signal front-end circuits on surface-mount boards.
- Providing a fixed negative supply rail for sensor signal conditioning circuits.
- Low-current negative voltage regulation in compact board-level power domains.
Design & Procurement Notes
Designers selecting this regulator should account for its fixed negative output, 100mA limit, and 0°C ~ 70°C operating envelope when defining load current, input voltage margin, and ambient conditions. Because the part is a linear regulator in an 8-SOIC surface-mount package, thermal dissipation from the input-to-output differential and layout of the 3.90 mm wide footprint should be considered. The 6 mA quiescent current and 50dB PSRR at 120Hz can help guide decisions in circuits where supply rejection and idle current are important, while over-temperature and short-circuit protection should be evaluated for fault conditions.
