JTDHT50

JTD · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

JTDHT50 from JTD, in a SOT-23. 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	GND	power_in	Ground pin (地) that serves as the regulator's return reference.
2	VOUT	power_out	Regulated output pin (输出); the HT50 output is nominally 5.0 V with a minimum 100 mA output current when VIN = VOUT + 2.0 V.
3	VIN	power_in	Input pin (输入); the datasheet limits the operating input voltage to 24 V, with an absolute maximum rating of +26 V.
