Product Overview
The flat face of the photographed black TO-92 body is printed in three lines: 78L05, then A 7K8, then JRC, and the rounded back of the same case carries a small circled logo stamp. 78L05 is the industry generic type and the A is the grade letter, which makes the maker's part number NJM78L05A from New Japan Radio, today Nisshinbo Micro Devices. There are 86 on the shelf and they are sold each.
Key Features
- Fixed 5 V positive output; the A grade is the tighter-tolerance version at 4.75 V to 5.25 V, per New Japan Radio's published NJM78L00 series data
- Output current 100 mA, per New Japan Radio's published NJM78L00 series data; this is the low-power 78L family, not the 1 A 78xx TO-220 family
- Quiescent current 2.0 mA typical and 6 mA maximum at Vin = 10 V with no load, per New Japan Radio's published NJM78L00 series data
- Operating temperature -40 C to +85 C, per New Japan Radio's published NJM78L00 series data
- Package: 3-lead TO-92, the plain A suffix in the part number; the UA and EA suffixes are surface-mount bodies and are not this part
- The photographed body is marked 78L05 over A 7K8 over JRC
Verify against New Japan Radio's published NJM78L00 series data before designing in.
Applications
- Local 5 V rail for a logic block fed from a higher supply
- Powering a small microcontroller or sensor that draws well under 100 mA
- Reference and bias supplies on analog boards
- Through-hole repair work where a 78L05 sat originally
Frequently Asked Questions
How many should I order? Order the count the build needs; 86 are on the shelf, so spares alongside the ones you need are no problem. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
How do I tell which lead is which? By the case: the TO-92 has a flat face carrying the 78L05 A JRC printing and a rounded back, and the pinout is referenced to that flat in New Japan Radio's published NJM78L00 series data. Check it there before soldering, because the 78L pinout is not the same order as the TO-220 78xx parts.
Three legs, a hundred milliamps, and a printed A that quietly stands for the tighter five volts.
