LP3962EMP-3.3

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-5

LP3962EMP-3.3 from Texas Instruments, in a SOT-223-5. 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	SD	input	Shutdown input: pulling it low (0 to 0.2V) puts the regulator in shutdown with about 15µA quiescent current, pulling it high (VIN−0.3V to VIN) enables the output, and it must be pulled high through a 10kΩ pull-up when used.
2	VIN	power_in	Input supply with an operating range of 2.5V to 7.0V and a survival limit of −0.3V to +7.5V.
3	VOUT	power_out	Regulated output with a survival limit of −0.3V to +7.5V, which must be diode-clamped to ground if the load is returned to a negative supply.
4	ERROR	output	Error flag that goes low when the output voltage drops 10% below nominal, with a maximum voltage of VIN+0.3V, requires a 10kΩ pull-up to be pulled high, and should be connected to ground if unused.
5	GND	power_in	Ground reference pin for the regulator.

CAD (KiCad official)

Symbol: LP3962EMP-3.3
Footprint: Package_TO_SOT_SMD:SOT-223-5
3D model: SOT-223-5, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.45 mm nominal SOT height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
3D model files: lp3962emp-3-3-etched.step / lp3962emp-3-3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lp3962emp-3-3.step / lp3962emp-3-3.glb are the bare package body.
