Frequently Asked Questions
What is the output voltage and current of UA78L08ACDR?
The UA78L08ACDR provides a fixed 8V regulated output with a maximum output current of 100mA. It accepts input voltages up to 30V and requires a minimum dropout voltage of approximately 1.7V above the output.
What package does the UA78L08ACDR come in?
The UA78L08ACDR is available in a 3-pin SOT-23 surface-mount package (SOT-23-3). This compact SMD package is suitable for space-constrained PCB designs and reflow soldering processes.
What are typical applications for the UA78L08ACDR?
Typical applications include local 8V rail regulation in IoT devices, portable instruments, sensor modules, and low-power consumer electronics. Its 100mA current rating and small SOT-23 package make it ideal for auxiliary power supplies on multi-rail boards.
What is the operating temperature range of UA78L08ACDR?
The UA78L08ACDR (commercial grade) operates from 0°C to +125°C. It includes internal thermal overload protection and short-circuit current limiting, making it robust across the full temperature range.
What are common alternatives or replacements for UA78L08ACDR?
Pin-compatible alternatives include the LM78L08 (ST/ON Semi), MC78L08 (ON Semiconductor), and NCV78L08 (ON Semi). For lower dropout, consider the TLV702 or TPS73008 series from Texas Instruments.
