Frequently Asked Questions
How does the LM2940T-9.0/NOPB fit into battery-powered designs?
The LM2940T-9.0/NOPB is a 9V 1A low dropout linear voltage regulator that supplies a stable 9V rail from inputs as low as 9.5V. Its 0.5V dropout at 1A extends usable battery life in portable equipment, and is widely used in automotive, industrial, and consumer electronics requiring a regulated 9V output.
How much dropout voltage does the LM2940T-9.0/NOPB require?
The LM2940T-9.0/NOPB has a typical dropout voltage of 0.5V at the full 1A output current. You only need the input to exceed 9.5V to maintain regulation, making it highly efficient compared to standard regulators that may require 1.5V–2V of headroom.
Is LM2940T-9.0/NOPB RoHS compliant?
Yes. The '/NOPB' suffix explicitly indicates that this device is lead-free and RoHS compliant. It does not contain lead (Pb) in its solder finish or package materials, meeting EU RoHS Directive requirements for use in modern electronics manufacturing.
Which components can replace the LM2940T-9.0/NOPB?
Compatible alternatives include the LM7809 (fixed 9V regulator, higher dropout ~2V), LM1117-9.0 (800mA LDO in SOT-223/TO-252), and LD1117-9.0 from STMicroelectronics. For higher efficiency in high-dissipation scenarios, a switching regulator like the TPS54360 is a viable option.
Which package does the LM2940T-9.0/NOPB use?
It comes in a TO-220-3 through-hole package with 3 pins: Input, Ground, and Output. This footprint matches classic 78xx series regulators, making it easy to drop in as a pin-compatible upgrade in existing designs. The metal tab is connected to the Ground pin.
