The 79L05-150 from UMW is a fixed -5V negative linear regulator capable of delivering 150mA of output current. Packaged in SOT-89-3, it offers a quiescent current of 6mA and 49dB of ripple rejection at 120Hz. This LDO provides a stable negative rail for applications requiring higher current than standard 100mA regulators.
- Higher 150mA Output: Supports more demanding negative rail loads than typical 100mA regulators.
- Stable -5V Fixed Output: Ensures consistent performance for bipolar analog circuits.
- Low Quiescent Current (6mA): Helps minimize power consumption in battery-operated devices.
- Compact SOT-89-3 Package: Saves PCB space while providing adequate thermal performance.
High-Current Negative Rails
With 150mA output, this regulator can power more demanding negative rail loads in multi-channel audio systems or industrial control boards.
Precision ADC/DAC Biasing
Mixed-signal converters often need a clean -5V reference; the 49dB PSRR ensures minimal noise coupling from the supply.
Automotive Analog Modules
In vehicle sensor interfaces, the 79L05-150 provides a stable negative rail for signal conditioning ICs operating in harsh environments.
Portable Medical Devices
Battery-powered medical monitors requiring bipolar supplies benefit from the low quiescent current and compact SOT-89-3 package.
Telecom Base Station Cards
Line cards needing negative bias for RF switches and attenuators can rely on this regulator for consistent -5V delivery.
Laboratory Power Supplies
As a secondary regulation stage, it provides a precise -5V rail for bench equipment with adjustable positive supplies.
