LP3982IMM-3.3

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · VSSOP-8-0.65mm

LP3982IMM-3.3 from Texas Instruments, in a VSSOP-8-0.65mm. 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 OUT output Regulated output voltage pin delivering up to 300 mA maximum output current at 3.3 V.
2 IN power_in Input power supply pin accepting 2.5 V to 6 V with 120 mV typical dropout voltage at 300 mA output current.
3 GND power_in Ground reference return pin for all internal and external circuits.
4 OUT output Regulated output voltage pin delivering up to 300 mA maximum output current at 3.3 V.
5 SET unconnected Internally disconnected in the LP3982IMM-3.3 fixed version; in adjustable versions, this input pin allows external resistor divider to program the regulated output voltage.
6 CC passive Noise reduction bypass capacitor connection to ground with optimum value of 33 nF for 37 μVRMS output noise reduction over 10 Hz to 100 kHz bandwidth.
7 SHDN input Shutdown control input requiring logic high minimum 2 V to enable the regulator or logic low maximum 0.4 V to power down to 1 nA typical quiescent current.
8 FAULT tri_state Active-low open-drain fault output that pulls low during out-of-regulation conditions including current limit, thermal shutdown above 160 °C, or when input-to-output differential approaches the 120 mV dropout threshold.
