LR8410B-TJ

LR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

LR8410B-TJ from LR, in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input voltage pin, rated for 7 V to 100 V continuous or transient input with a 110 V absolute maximum VIN.
2 GND power_in Ground pin, the common reference for the regulator.
3 EN input CMOS-compatible enable pin that turns the regulator on above 1.5 V and enters low-current shutdown below 0.4 V (ISD 8 µA typ, 15 µA max at VEN = 0 V).
4 FB input Feedback pin connected to the internal 0.8 V reference (0.788 V to 0.812 V) through the external divider, where VOUT = 0.8 V × (R1 + R2) / R2 and feedback pin current is 0.11 µA max.
5 VOUT power_out Regulated output voltage pin, adjustable from 1.2 V to 90 V and rated for up to 50 mA output current.
